Computer room relocation plan
Part 1: Computer room relocation plan
With the expansion of the information system, the data center equipment room can not meet the demand in terms of area and supporting infrastructure. In response to this situation, most power supply bureaus chose to rebuild the equipment room. How to migrate servers, storage, and network devices to a new computer room is a tricky problem.
Through analysis, it is found that there are two difficulties in the relocation of the equipment room. First, the risk of relocation is high. Many equipments have already passed the warranty period and are relatively old. Therefore, the protection of equipment safety and data security is particularly important. Second, it has a greater impact on users. The migration of the equipment room has a great impact on the development of business work, and even the business interruption of the entire unit, leading to serious consequences. Therefore, a lot of preparation work should be done before the relocation, a careful relocation plan should be formulated, and corresponding preventive measures and remedial measures should be provided to ensure the safety of data and application systems to the greatest extent.
1 Relocation plan
In order to minimize the impact of relocation on the application system, the online relocation method can be adopted, that is, a smooth network transition environment is established, and data storage is taken as the core to ensure the stability and continuity of the network and the application system, and the maximum shortening is achieved. The interruption time of the system operation. The relocation plan includes the following aspects:
The equipment relocation plan, the main content is the relocation equipment statistics, relocation supporting tools, relocation schedule and personnel arrangement, and the location plan of the equipment after relocation.
The network cutover solution includes the network cutover process and network topology changes before and after the cutover.
System and data backup solutions, including backup methods and time.
Emergency solutions, including hardware failures, operating system failures, database and application system failures, storage devices, and data failure emergency plans.
In the plan, first determine the list of equipment to be relocated and classify the equipment; secondly, arrange the equipment according to the system and arrange a reasonable relocation order. The core system can be relocated on weekends or on weekdays, and non-core systems can be relocated on weekdays. For a dual-machine running device, the standby system can be moved, debugged, and operated normally, and then the host is relocated to the new equipment room.

Figure 1 Preparation before relocation
2 relocation steps
Before the relocation, we will make a notice to unify the downtime of the relocation process, and then provide a hotline to contact the Ministry of Information to coordinate the relocation of various professions.
Information release: The information department will release information in advance to inform the specific relocation time plan.
Network interconnection: Determine the fiber-optic line connectivity between the new data center room and the old machine room.
Check the environmental conditions and availability of the equipment room: Check the normal operation conditions of the air conditioner, power supply, fire protection, and integrated wiring of the new equipment room, and conduct network connectivity testing to ensure the availability of the network.
Apply the administrator to check if the application is working properly, and the host administrator checks to see if the host is running normally.
Data backup: Before the relocation, make a backup of the system.
Confirm that the relocation tool is in place.
Confirm hotline support or on-site support for key business system related manufacturers.
Apply the administrator to quit the application, the host administrator stops the host, and then the relocation group performs the disassembly, cleaning, relocation, racking, and network/KVM access of the host. During the equipment relocation process, the equipment should be prevented from colliding. Anti-dust, waterproof, etc., at the same time must be in strict accordance with the equipment layout diagram, equipment back wiring diagram to complete the equipment racking, wiring and other work.
The host administrator powers on the device and performs host testing, and the application administrator is responsible for applying the test.
After the equipment is in normal operation, each relocation group updates the identification of the equipment and wiring lines in a timely manner.
It is recommended that personnel changes and system relocation be carried out in stages. That is, the staff is working in the new building, the system is in the old building, and after the staff is stable, the system is gradually moved.
3 Pre-preparation to be solid
In order to reduce errors and smooth migration, you need to complete the following tasks before relocation.
Check if the environment of the new building office area is available. Check if the data center room environment is available.
The fiber-optic network between the new building and the old building is securely connected, and the new building is connected to the IDC data center network of the old building with at least 2 pairs of fiber.
Complete the equipment to relocate and change the corresponding configuration according to the regional network, metropolitan area network and IDC internal network construction requirements, so as to realize the construction of the new building regional network and realize the networking with the metropolitan area network. Realize the construction of the data center network of the new building and realize the networking with the metropolitan area network.
Develop a new server room server layout table. Before the relocation, detailed layout of the cabinet, equipment connection diagram and physical connection diagram after equipment relocation should be provided to ensure the scientific order of relocation.
Each system administrator needs to prepare the system emergency plan and implement whether to contact the system manufacturer to assist the system to relocate according to the system situation, so as to ensure timely and proper handling of security events that may be caused by equipment relocation.
The server device is to be prepared for spare parts.
Be prepared to relocate the equipment, tools, and auxiliary materials and consumables.
The backup system is backed up 24 hours before the relocation.
Confirm the handling company, complete the inspection of the equipment room and the relocation channel, and confirm the relocation transportation route.
4 Notes
Before the relocation, the new equipment room should be tested for fiber and twisted pair. Whether the server rails of the old equipment room are consistent with the cabinets of the new equipment room, need to be confirmed in advance.
The operation and shutdown of the equipment and equipment must be carried out in strict accordance with the on-site operating procedures; all types of equipment have clear test methods; ready to apply software, including middleware, database, software application, etc., before the relocation Centralized preparation and filing.
Data backup Before the system is migrated, if necessary, the operating system backup of important systems must be done to ensure the integrity and correctness of the data.
During the relocation process, pay attention to the protection of the label and prevent the label from falling off, especially the small parts and screws of the server. Make labels when disassembling, so as not to affect the subsequent reorganization.
After the equipment is shut down and the power is turned off, it is necessary to wait until the internal parts of the equipment are fully discharged before demolition can be carried out to minimize the possibility of damage to the original parts during the system relocation process.
Responsibility to people, equipment must be registered and transported with special personnel responsible.
Relocation personnel should wear static-loading gloves, and try to be as light as possible during the relocation process to avoid collisions; package and relocate outside the new and old equipment rooms.
The vehicle used for relocation should pass the annual inspection and have the relevant safety certificate. The driver should have a driver's license and have the driving experience of relocating the vehicle. The driver's mental state is good before the relocation of the vehicle.
After the equipment is relocated, the network and storage access must be made according to the original access conditions to ensure that the connection mode and operating environment of each system device remain unchanged.
Relocation related personnel must have a centralized office for office use during the relocation period. In the case of a long problem during the relocation process, shift work is required to ensure sufficient energy and physical strength.
5 Countermeasures
In the process of relocation, it is easy to cause three aspects of hardware damage, personal injury, and faults. For them, at least the following measures should be taken.
Pay attention to the physical condition and mental state of the staff. If the work requirements are not met, appropriate personnel should be arranged to replace them.
Relocation, demolition, and installation of equipment should be handled lightly and gently, and a safety guardian should be responsible for the whole process of guiding and monitoring.
Before transportation, use equipment such as wrapping paper and sponge to reinforce the equipment. The transportation route should be smoother.
Use the UPS output power supply for equipment debugging, operation, etc. The workplace should use electricity safely. Safety and qualified tools should be used to regulate operation and prevent accidental contact with live equipment.
Prepare system restart operation instructions and system failure emergency operation tickets, and actually test the feasibility of the operation before relocation to ensure timely and proper handling of security events that may be caused by equipment relocation.
Before relocating equipment, check whether the Fibre Channel between the old and new buildings can communicate normally; restart the original building computer room server, check whether the server node status and application status of the original building room are normal, real-time data, real-time alarm data, database read and write functions, etc. Whether it is normal, whether the operating system is normal, the disk space and the disk file can be read and written normally; backup of important data and network configuration, so that the configuration or data can be restored in time.
When the system fails to start, gradually troubleshoot the faults from the software, operating system, network configuration, and hardware devices. Arrange small computer operating systems, Oracle database manufacturers on-site duty, to deal with unexpected problems.
6 Conclusion

Part 2: Computer room relocation plan
I. Overview
With the planning and development of the city and enterprises, the government, enterprises and institutions will involve a variety of situations such as the construction, relocation and reconstruction of office and production sites. The migration of the computer room is a very important task involving many different types of equipment, including units. Core data, application and many other core assets, the migration of the computer room can be said to be a sophisticated system engineering.
During the relocation process, the air conditioning environment and power control of the original site will be optimized and adjusted to meet the increasing demand of the system. The normative and scientific adjustment of these adjustments will be critical to the operation of the engine room. The system poses a serious threat.
The equipment room relocation service solution is a service plan provided to ensure the smooth, orderly and efficient implementation of the relocation of the equipment room, and to ensure the normal and smooth relocation, recovery and operation of the network equipment of the original equipment room.
Second, the overall plan
In the process of system relocation, it is usually divided into three stages: planning, testing, and implementation, as shown in the following figure.
The relocation of business system equipment needs to go through the preliminary research preparation, the effective backup of the system before the relocation, the formulation and testing of the emergency plan, the installation and installation of the system after the relocation, the system integrity test and the establishment of an effective monitoring mechanism. Every step of the work requires a well-planned plan and implementation in strict accordance with the plan. Any mistakes in any of the links will affect the progress of the entire relocation work and increase the risk. Therefore, we should make a careful plan and document before the relocation, which should include an accurate relocation implementation schedule and specific implementation steps as well as emergency plans in case of emergency. At the same time, it is necessary to clearly arrange specific responsible personnel for each step in the plan to ensure the implementation and implementation of the relocation plan.
Third, the implementation process
The system relocation implementation process includes five processes: preparation, disassembly, shipment, installation, and commissioning, as follows:
1. Preparation: including preparations for personnel and equipment preparation, preparation for new equipment room environment, network environment, backup, labeling of all equipment on site, modules, equipment preparation, etc.
2. Disassembly: mainly only the core equipment is unloaded, etc.
3. Shipment: mainly refers to the process of transporting equipment from the original equipment room to the new equipment room.
4. Installation: It mainly includes the cabinets in place, independent installation of each cabinet, network connection, strong electric wiring, floor hole adjustment and so on.

Part 3: Computer room relocation plan
I. Overview of the relocation of the computer room
The relocation of the equipment room, the docking of the new and old machine rooms will also reflect the level of this project.
The relocation of the production system has the characteristics of short time, complicated system structure, long test time, expensive equipment, many personnel, and complex levels. The relocation of this project is very tight, and the stability between equipment is also a test. Therefore, it is necessary to coordinate the relationship between the personnel of each unit and work together to complete the relocation project within the scheduled time.
This program is based on the premise of not affecting the daily work of XXX or minimizing the impact, that is, starting the relocation work before the rest day, and completing the relocation and installation of the entire server and network equipment before the working day. test. And after the boot, continue to track the operation of the system, and handle the abnormal situation of the system at any time. Of course, this relocation task can be completed with the full coordination and cooperation of all aspects of XXX.
Our company has great advantages in upstream supplier resources. For example, equipment failure occurs during relocation work. In addition to spare parts provided in spare parts, we can coordinate resources of all parties to solve customer equipment failure problems as quickly as possible.
Second, the relocation plan
1. Implementation process:
The process is mainly based on the needs before the relocation, mainly to understand the current system equipment situation and system operation. Develop detailed relocation plans and contingency plans for the situation.
2. Professional engineers understand the current status of the user's current computer room and the specific requirements after the relocation. Fully consider the various situations that may occur during the implementation process, and customize the detailed feasibility of the migration implementation plan to minimize the impact of the room migration work on users.
3. Prepare the physical layout table, connection table and cable number table before and after the relocation. It can be classified into multiple systems according to user conditions.
4. XXX technicians need to work closely together during the relocation process.
5. In order to ensure the smooth, orderly and safe relocation of the relocation work, a detailed relocation process will be formulated, and a detailed division of labor will be carried out. The specific work will be arranged to the people and the responsibility will be passed.
6. The principle of each work in the relocation work is at least arranged to ensure the accuracy of the work.
Third, the detailed implementation plan
The equipment was relocated for two days and the time was tight. We will try our best to refine the task arrangement to ensure the smooth progress of the work.
In order to make the relocation smooth and smooth, and to ensure the normal operation of the equipment after the relocation, we have developed a series of simple and clear worksheets to help the project implementers determine whether the work to be performed in the various relocations is completed. Avoid work mistakes and avoid delays in relocation work.
1. Implementation process:
2. Destination computer room requirements:
It is necessary to check whether the necessary equipment and facilities of the target computer room meet the requirements before the relocation. This worksheet is a prerequisite for ensuring the stable and normal operation of the equipment after the relocation. Before the relocation, the responsible person of the relocation and the relevant personnel shall confirm and confirm.

Is the broadband access in the equipment room complete?
Is the required IP address in place?
3. Equipment is shut down before relocation
The preparation work before the equipment is relocated is very important and necessary, because according to our experience, the equipment will shut down after a long time to turn on, there will be unexpected failures, which will result in failure to start or other hardware failures. At the same time, it is also possible that the server cannot be serviced normally after the server is started due to a network connection error. Therefore, data backup, connection connection, address planning, and spare parts preparation are all necessary.
1) Data backup
Data backup requires the relocation leader and system administrator to back up before the equipment is moved. This backup is the last backup before the relocation, and it is a job that must be done carefully. It is a guarantee of rapid recovery after a device failure. Backups include data backups of the server. Backup of configuration files of network devices, etc.
This worksheet is confirmed by the relocation leader and the system administrator at the time of backup.

2) Device marking
If the device does not have a name, you need to name the device and print the name of the label on each device with a label. This table is used for records where XXX does not have a detailed mark on the device. If there are XXX network administrators with detailed tags, replace this table. This table is mainly used for quick connection after equipment relocation, to avoid the failure of normal access due to connection errors, delays in relocation events, etc.

3) Shutdown of the equipment
The device needs to be shut down normally according to the normal rules. The PC server needs to stop the service and then shut down. The minicomputer disk array performs each step in order to complete the shutdown according to the operating procedures.
After the shutdown, all the equipments are disassembled in the order from top to bottom. The off-duty personnel are professionals who have many years of construction experience in our company. All cables should be removed first when the rack is removed. All equipment should be handled gently to avoid unnecessary loss. After the equipment is removed from the rack, it will be transported by the porter to the destination room.
If you want to use a small cart and other transportation tools, you need to put cushions between the vehicle and the equipment to avoid excessive vibration during transportation, resulting in loose equipment accessories.
4) Equipment rack
The equipment rack is operated in the opposite order.
The shelves should be placed according to the layout of the cabinets designed by both parties in advance. The layout drawings need to be designed reasonably, save space, and be easy to maintain and beautiful.

7. Detailed ip address allocation table
8. Ensure that the equipment needed for the relocation is in place before the relocation and construction
9. Classification and statistics of equipment
The equipment includes UPS, patch panels, core switches, servers, firewalls, storage devices, etc. We provide further detailed device statistics for the equipment statistics currently involved in the equipment room, including equipment model, configuration, network, etc. Before the relocation, the corresponding form record document is given, the relevant auxiliary equipment accessories are determined, and the detailed record document is also required.
2. The relocation party is ready to work
1. Equipped with the equipment and tools needed for the relocation process.
2. Personnel are in place, identify the people and assign the tasks of each person.
3. Check the relocation equipment according to the equipment provided by the relocated party.
4. Confirm the layout of the device
After the basic design of the new equipment room is completed, we need to plan the placement of each cabinet and each network equipment in advance. The specific size of the machine can be measured in advance, and then the specific position of the machine can be planned on site to strive for the most reasonable and full use of the effective space of the machine room. Here you need to pay attention to the problem: if you need to expand the cabinet, put the data information points of the integrated wiring on the distribution frame in advance, so that if the network equipment such as the switch router is moved over and the jumper is installed, the network will be Can be used normally.
Three equipment testing
1. Comprehensive prevention of static electricity Although the computer works on electricity, static electricity can cause fatal damage to the computer, especially if it causes permanent damage to the motherboard chip. There are many reasons for static electricity: various power supply devices may generate static electricity, computer CRT displays may generate static electricity, and mobile phones and walkie-talkies in operation may generate a large amount of static electricity in the surrounding space. This requires us to pay special attention to static electricity interference and comprehensive prevention.
Try to make the grounding of the server and its peripherals as good as possible.
If the equipment is not grounded, when it is necessary to touch the board inside, it should be discharged with a grounding conductor or other discharge facility.
When you operate the device, you can touch the metal outside the chassis to remove the static electricity you carry. Ensure that the layout inside the chassis is reasonable. Generally speaking, the layout of the components inside the server chassis and the space design are scientifically arranged, and the combination of each other is compact but not messy. We must maintain this layout when adding and uninstalling the server device. effect. Note: There should be a considerable amount of reserved space inside the chassis to form a reasonable “duct”. This is because the CPU is not only the only heat source, but also high-speed hard disks, CD players, various chips and boards. Heat is generated in a small space, so the air inside the chassis must be able to flow sufficiently when the fan is turned.
2. The server restarts correctly.
Shutdown operation:
Close the operating system;
Turn off the power of the host;
Turn off the peripheral power supply;
Turn off the power of other devices and the power of the cabinet;
Turn off the main power.
Boot operation:
Turn on the main power supply;
Turn on the power of the computer cabinet;
Turn on the power of the external device;
After the external device self-test is completed, the host power is finally turned on.
Power on the machine, if the machine can start, the system is in good condition; if there is a problem after powering up, it means that the system has problems before the relocation, not caused during the relocation process. The relocation party is not responsible for it.
3. UPS power supply restarts correctly
The order of properly turning off the UPS power supply should be: first turn off the load connected to the output of the UPS power supply one by one, then turn off the power switch on the power control cabinet.
Open the correct order of the UPS power supply: Be careful not to touch the magnetic material during the relocation process. The correct switch steps Generally, the correct sequence for turning on the UPS power supply should be: first check the power polarity of the input end of the UPS power supply and the power supply of the mains power supply line. Whether the polarity connection is consistent, and then check whether the total power of the load connected to the UPS power supply is within the rated power of the UPS power supply; after satisfying the above conditions, turn on the power switch on the UPS power control cabinet to let the utility power The battery pack in the UPS is powered. After a period of time, the power switch of the load is turned on one by one. This ensures the load current and does not cause excessive impact on the internal power supply line of the UPS power supply, thereby effectively ensuring that the UPS power supply is not protected. internal injury.
Restart the power supply. If it can be started, the equipment is in good condition. If the operation is not normal, it is not caused during the relocation process. The relocation party is not responsible for it.

Try to make the grounding of the server and its peripherals as good as possible.
• If the equipment is not grounded, when it is necessary to touch the board inside, it should be discharged with a grounding conductor or other discharge facility.
When you operate the device, you can touch the metal outside the chassis to remove the static electricity you carry. Ensure that the layout inside the chassis is reasonable.

Heat is generated in a small space, so the air inside the chassis must be able to flow sufficiently when the fan is turned.
2. Disassembly and cleaning principle of the server: first turn off all the server workstations, turn off the power equipment such as the switch router, then turn off the total power supply, and finally remove the server.
Hard disk: The server hard disk is the data warehouse of the server, and all software and user data are stored here. For the user, the hard disk data stored on the server is the most valuable, so the reliability of the hard disk is very important. Pay special attention to the hard disk order in the server disk array during the disassembly and assembly of the server. If 10 hard disks are used as the array, at the time of initialization, the 10 hard disks should be sequentially placed in the disk array, which are divided into first, second, and tenth hard disks. If the disk array has sequential requirements, the hard disk must be inserted back into the disk array in the original placement order. Otherwise, the data may be inconsistent and the data may be lost due to the hard disk order.
The disassembly and assembly of the CPU requires attention to the following points: The bottom of the CPU is the core part consisting of dense integrated circuits. These small pins are easily deformed by extrusion, and if one of these small pins is bent, the CPU will not work properly. must be careful. The CPU socket of the motherboard and the side of the CPU with the small pin are exactly matched, so as long as the direction is correct when inserted, the CPU can be inserted into the motherboard with a single push. Don't use a lot of effort. If the CPU doesn't plug in, it's a problem with the direction of insertion. If the orientation is not correct when installing the CPU fan, it cannot be installed. Therefore, as with the CPU, do not use too much force, excessive force will cause excessive pressure between the motherboard and the CPU and cause damage.
When the cable is connected, the device connected through the cable should be powered off. That is, the power of the device should be turned off before the cable is connected. Otherwise, if the cable is connected with power, it may cause unpredictable damage to the equipment.
When the server board is added to the server board, be sure to select the angle when inserting the slot, and the power is even, so as not to damage the board or slot.
The motherboard should be more careful with the operation of the motherboard. The installation must be stable and prevent the motherboard from being deformed to avoid damage to the electronic circuit on the motherboard.
Open the casing to clean the dust on the inner surface of the servo. For large areas of dust on the inner surface of the server, use a dry cloth to spray with a professional cleaning solution. The cloth should be as dry as possible and should be dried after wiping. All plugs and sockets, expansion slots, memory slots and boards should not be wiped with water. You can also use a brush or blow off dust.
3. Host disassembly cleaning principle:
Turn off the system, disconnect the system power, and disassemble it from each cabinet into a removable part.
Before opening the case, your hands should touch the ground or the wall to release static electricity from your body. Maintain a certain humidity, air drying is also prone to static electricity, ideal humidity should be 40% -60%;
Open the casing to clean the dust on the inner surface of the servo. For large areas of dust on the inner surface of the server, use a dry cloth to spray with a professional cleaning solution.

You can also use a brush or blow off dust.
Cleaning the memory and strip memory strips and various adapter cards involves dusting and cleaning the gold fingers on the board. You can use a brush or blow off dust. You can also use an eraser to wipe off the dust, oil or oxide layer on the surface of the gold finger. You can't use sandpaper to wipe the gold finger, otherwise it will damage the extremely thin coating.
4. Cleaning principle of UPS power supply:
The order of properly closing the UPS power supply should be: first turn off the load connected to the output of the UPS power supply one by one, then turn off the power switch on the power control cabinet.
We need to pay attention to the cleaning of the UPS: Do not touch the magnetic material during the cleaning process?
Master the situation of UPS, and strive to make every cable have a heart, all the configuration, each interface must be clear, battery, cable must be labeled. When labeling equipment, it is generally the method of attaching the equipment nameplate, and the cable adopts a special identification ring. The planning of equipment labels is generally formulated by each unit. There is no uniform standard. Here we can consider numbering according to the type, function and area of the equipment. Each machine must be labeled before moving, especially for multi-connected machines. Each wiring connection is labeled and corresponds to the other end of the wiring.
Open the casing to clean the dust on the inner surface of the servo. For large areas of dust on the inner surface of the server, use a dry cloth to spray with a professional cleaning solution. The cloth should be as dry as possible and should be dried after wiping. All kinds of plugs and sockets, and boards should not be wiped with water. You can also use a brush or blow off dust.
Because all equipment will age after prolonged use, all equipment will be reinstalled after the correct equipment cleaning work is completed. If the power is turned on, if the equipment can be started, if the equipment is in good condition, if the operation is not normal, it is not caused during the relocation process. The relocation party is not responsible for it.
Five equipment relocation and installation
1. Equipment relocation sequence
Generally speaking, the order of equipment relocation is: server system, UPS, communication system, then network equipment, terminal equipment, and so on. Of course, you can also consider moving the equipment that does not affect the daily business to the new building, such as some monitors, terminals, mainframes, power cords, etc.
2. Relocation of equipment
After all equipment is cleaned, assembled, and tested, all equipment is boxed, reinforced, and protected against collision. Loading to the destination.
Equipment installation
Connect all devices correctly according to network planning.
Six post-relocation work
1. When placing the UPS in the new equipment room, pay attention to it: Weight bearing: When the UPS is configured for long delay, the battery may be heavy. In this case, the floor load should be considered. Space size: When the UPS is to be maintained, the engineering personnel have certain space for implementation. Grounding: There is a good grounding system, the general grounding resistance should be less than 5 ohms
2. When placing the server in the new computer room, please pay attention: when we put the server on the rack and do physical connection, we need to open the server to check whether the data is damaged and related. The setting of the software. In general, the work to be done roughly includes the following items:
1. Recovery of the server status to see if data loss or damage has occurred. If there is damage to this data, don't be afraid! We should restore the data before the relocation.

With the expansion of the information system, the data center equipment room can not meet the demand in terms of area and supporting infrastructure. In response to this situation, most power supply bureaus chose to rebuild the equipment room. How to migrate servers, storage, and network devices to a new computer room is a tricky problem.
Through analysis, it is found that there are two difficulties in the relocation of the equipment room. First, the risk of relocation is high. Many equipments have already passed the warranty period and are relatively old. Therefore, the protection of equipment safety and data security is particularly important. Second, it has a greater impact on users. The migration of the equipment room has a great impact on the development of business work, and even the business interruption of the entire unit, leading to serious consequences. Therefore, a lot of preparation work should be done before the relocation, a careful relocation plan should be formulated, and corresponding preventive measures and remedial measures should be provided to ensure the safety of data and application systems to the greatest extent.
1 Relocation plan
In order to minimize the impact of relocation on the application system, the online relocation method can be adopted, that is, a smooth network transition environment is established, and data storage is taken as the core to ensure the stability and continuity of the network and the application system, and the maximum shortening is achieved. The interruption time of the system operation. The relocation plan includes the following aspects:
The equipment relocation plan, the main content is the relocation equipment statistics, relocation supporting tools, relocation schedule and personnel arrangement, and the location plan of the equipment after relocation.
The network cutover solution includes the network cutover process and network topology changes before and after the cutover.
System and data backup solutions, including backup methods and time.
Emergency solutions, including hardware failures, operating system failures, database and application system failures, storage devices, and data failure emergency plans.
In the plan, first determine the list of equipment to be relocated and classify the equipment; secondly, arrange the equipment according to the system and arrange a reasonable relocation order. The core system can be relocated on weekends or on weekdays, and non-core systems can be relocated on weekdays. For a dual-machine running device, the standby system can be moved, debugged, and operated normally, and then the host is relocated to the new equipment room.

Figure 1 Preparation before relocation
2 relocation steps
Before the relocation, we will make a notice to unify the downtime of the relocation process, and then provide a hotline to contact the Ministry of Information to coordinate the relocation of various professions.
Information release: The information department will release information in advance to inform the specific relocation time plan.
Network interconnection: Determine the fiber-optic line connectivity between the new data center room and the old machine room.
Check the environmental conditions and availability of the equipment room: Check the normal operation conditions of the air conditioner, power supply, fire protection, and integrated wiring of the new equipment room, and conduct network connectivity testing to ensure the availability of the network.
Apply the administrator to check if the application is working properly, and the host administrator checks to see if the host is running normally.
Data backup: Before the relocation, make a backup of the system.
Confirm that the relocation tool is in place.
Confirm hotline support or on-site support for key business system related manufacturers.
Apply the administrator to quit the application, the host administrator stops the host, and then the relocation group performs the disassembly, cleaning, relocation, racking, and network/KVM access of the host. During the equipment relocation process, the equipment should be prevented from colliding. Anti-dust, waterproof, etc., at the same time must be in strict accordance with the equipment layout diagram, equipment back wiring diagram to complete the equipment racking, wiring and other work.
The host administrator powers on the device and performs host testing, and the application administrator is responsible for applying the test.
After the equipment is in normal operation, each relocation group updates the identification of the equipment and wiring lines in a timely manner.
It is recommended that personnel changes and system relocation be carried out in stages. That is, the staff is working in the new building, the system is in the old building, and after the staff is stable, the system is gradually moved.
3 Pre-preparation to be solid
In order to reduce errors and smooth migration, you need to complete the following tasks before relocation.
Check if the environment of the new building office area is available. Check if the data center room environment is available.
The fiber-optic network between the new building and the old building is securely connected, and the new building is connected to the IDC data center network of the old building with at least 2 pairs of fiber.
Complete the equipment to relocate and change the corresponding configuration according to the regional network, metropolitan area network and IDC internal network construction requirements, so as to realize the construction of the new building regional network and realize the networking with the metropolitan area network. Realize the construction of the data center network of the new building and realize the networking with the metropolitan area network.
Develop a new server room server layout table. Before the relocation, detailed layout of the cabinet, equipment connection diagram and physical connection diagram after equipment relocation should be provided to ensure the scientific order of relocation.
Each system administrator needs to prepare the system emergency plan and implement whether to contact the system manufacturer to assist the system to relocate according to the system situation, so as to ensure timely and proper handling of security events that may be caused by equipment relocation.
The server device is to be prepared for spare parts.
Be prepared to relocate the equipment, tools, and auxiliary materials and consumables.
The backup system is backed up 24 hours before the relocation.
Confirm the handling company, complete the inspection of the equipment room and the relocation channel, and confirm the relocation transportation route.
4 Notes
Before the relocation, the new equipment room should be tested for fiber and twisted pair. Whether the server rails of the old equipment room are consistent with the cabinets of the new equipment room, need to be confirmed in advance.
The operation and shutdown of the equipment and equipment must be carried out in strict accordance with the on-site operating procedures; all types of equipment have clear test methods; ready to apply software, including middleware, database, software application, etc., before the relocation Centralized preparation and filing.
Data backup Before the system is migrated, if necessary, the operating system backup of important systems must be done to ensure the integrity and correctness of the data.
During the relocation process, pay attention to the protection of the label and prevent the label from falling off, especially the small parts and screws of the server. Make labels when disassembling, so as not to affect the subsequent reorganization.
After the equipment is shut down and the power is turned off, it is necessary to wait until the internal parts of the equipment are fully discharged before demolition can be carried out to minimize the possibility of damage to the original parts during the system relocation process.
Responsibility to people, equipment must be registered and transported with special personnel responsible.
Relocation personnel should wear static-loading gloves, and try to be as light as possible during the relocation process to avoid collisions; package and relocate outside the new and old equipment rooms.
The vehicle used for relocation should pass the annual inspection and have the relevant safety certificate. The driver should have a driver's license and have the driving experience of relocating the vehicle. The driver's mental state is good before the relocation of the vehicle.
After the equipment is relocated, the network and storage access must be made according to the original access conditions to ensure that the connection mode and operating environment of each system device remain unchanged.
Relocation related personnel must have a centralized office for office use during the relocation period. In the case of a long problem during the relocation process, shift work is required to ensure sufficient energy and physical strength.
5 Countermeasures
In the process of relocation, it is easy to cause three aspects of hardware damage, personal injury, and faults. For them, at least the following measures should be taken.
Pay attention to the physical condition and mental state of the staff. If the work requirements are not met, appropriate personnel should be arranged to replace them.
Relocation, demolition, and installation of equipment should be handled lightly and gently, and a safety guardian should be responsible for the whole process of guiding and monitoring.
Before transportation, use equipment such as wrapping paper and sponge to reinforce the equipment. The transportation route should be smoother.
Use the UPS output power supply for equipment debugging, operation, etc. The workplace should use electricity safely. Safety and qualified tools should be used to regulate operation and prevent accidental contact with live equipment.
Prepare system restart operation instructions and system failure emergency operation tickets, and actually test the feasibility of the operation before relocation to ensure timely and proper handling of security events that may be caused by equipment relocation.
Before relocating equipment, check whether the Fibre Channel between the old and new buildings can communicate normally; restart the original building computer room server, check whether the server node status and application status of the original building room are normal, real-time data, real-time alarm data, database read and write functions, etc. Whether it is normal, whether the operating system is normal, the disk space and the disk file can be read and written normally; backup of important data and network configuration, so that the configuration or data can be restored in time.
When the system fails to start, gradually troubleshoot the faults from the software, operating system, network configuration, and hardware devices. Arrange small computer operating systems, Oracle database manufacturers on-site duty, to deal with unexpected problems.

Part 2: Computer room relocation plan
I. Overview
With the planning and development of the city and enterprises, the government, enterprises and institutions will involve a variety of situations such as the construction, relocation and reconstruction of office and production sites. The migration of the computer room is a very important task involving many different types of equipment, including units. Core data, application and many other core assets, the migration of the computer room can be said to be a sophisticated system engineering.
During the relocation process, the air conditioning environment and power control of the original site will be optimized and adjusted to meet the increasing demand of the system. The normative and scientific adjustment of these adjustments will be critical to the operation of the engine room. The system poses a serious threat.
The equipment room relocation service solution is a service plan provided to ensure the smooth, orderly and efficient implementation of the relocation of the equipment room, and to ensure the normal and smooth relocation, recovery and operation of the network equipment of the original equipment room.
Second, the overall plan
In the process of system relocation, it is usually divided into three stages: planning, testing, and implementation, as shown in the following figure.
The relocation of business system equipment needs to go through the preliminary research preparation, the effective backup of the system before the relocation, the formulation and testing of the emergency plan, the installation and installation of the system after the relocation, the system integrity test and the establishment of an effective monitoring mechanism. Every step of the work requires a well-planned plan and implementation in strict accordance with the plan. Any mistakes in any of the links will affect the progress of the entire relocation work and increase the risk. Therefore, we should make a careful plan and document before the relocation, which should include an accurate relocation implementation schedule and specific implementation steps as well as emergency plans in case of emergency. At the same time, it is necessary to clearly arrange specific responsible personnel for each step in the plan to ensure the implementation and implementation of the relocation plan.
Third, the implementation process
The system relocation implementation process includes five processes: preparation, disassembly, shipment, installation, and commissioning, as follows:
1. Preparation: including preparations for personnel and equipment preparation, preparation for new equipment room environment, network environment, backup, labeling of all equipment on site, modules, equipment preparation, etc.
2. Disassembly: mainly only the core equipment is unloaded, etc.

Part 3: Computer room relocation plan
I. Overview of the relocation of the computer room
The relocation of the equipment room, the docking of the new and old machine rooms will also reflect the level of this project.
The relocation of the production system has the characteristics of short time, complicated system structure, long test time, expensive equipment, many personnel, and complex levels. The relocation of this project is very tight, and the stability between equipment is also a test. Therefore, it is necessary to coordinate the relationship between the personnel of each unit and work together to complete the relocation project within the scheduled time.
This program is based on the premise of not affecting the daily work of XXX or minimizing the impact, that is, starting the relocation work before the rest day, and completing the relocation and installation of the entire server and network equipment before the working day. test. And after the boot, continue to track the operation of the system, and handle the abnormal situation of the system at any time. Of course, this relocation task can be completed with the full coordination and cooperation of all aspects of XXX.
Our company has great advantages in upstream supplier resources. For example, equipment failure occurs during relocation work. In addition to spare parts provided in spare parts, we can coordinate resources of all parties to solve customer equipment failure problems as quickly as possible.
Second, the relocation plan
1. Implementation process:
The process is mainly based on the needs before the relocation, mainly to understand the current system equipment situation and system operation. Develop detailed relocation plans and contingency plans for the situation.
2. Professional engineers understand the current status of the user's current computer room and the specific requirements after the relocation. Fully consider the various situations that may occur during the implementation process, and customize the detailed feasibility of the migration implementation plan to minimize the impact of the room migration work on users.
3. Prepare the physical layout table, connection table and cable number table before and after the relocation. It can be classified into multiple systems according to user conditions.
4. XXX technicians need to work closely together during the relocation process.
5. In order to ensure the smooth, orderly and safe relocation of the relocation work, a detailed relocation process will be formulated, and a detailed division of labor will be carried out. The specific work will be arranged to the people and the responsibility will be passed.
6. The principle of each work in the relocation work is at least arranged to ensure the accuracy of the work.
Third, the detailed implementation plan
The equipment was relocated for two days and the time was tight. We will try our best to refine the task arrangement to ensure the smooth progress of the work.
In order to make the relocation smooth and smooth, and to ensure the normal operation of the equipment after the relocation, we have developed a series of simple and clear worksheets to help the project implementers determine whether the work to be performed in the various relocations is completed. Avoid work mistakes and avoid delays in relocation work.
1. Implementation process:
2. Destination computer room requirements:
It is necessary to check whether the necessary equipment and facilities of the target computer room meet the requirements before the relocation. This worksheet is a prerequisite for ensuring the stable and normal operation of the equipment after the relocation. Before the relocation, the responsible person of the relocation and the relevant personnel shall confirm and confirm.

3. Equipment is shut down before relocation
The preparation work before the equipment is relocated is very important and necessary, because according to our experience, the equipment will shut down after a long time to turn on, there will be unexpected failures, which will result in failure to start or other hardware failures. At the same time, it is also possible that the server cannot be serviced normally after the server is started due to a network connection error. Therefore, data backup, connection connection, address planning, and spare parts preparation are all necessary.
1) Data backup
Data backup requires the relocation leader and system administrator to back up before the equipment is moved. This backup is the last backup before the relocation, and it is a job that must be done carefully. It is a guarantee of rapid recovery after a device failure. Backups include data backups of the server. Backup of configuration files of network devices, etc.
This worksheet is confirmed by the relocation leader and the system administrator at the time of backup.

3) Shutdown of the equipment
The device needs to be shut down normally according to the normal rules. The PC server needs to stop the service and then shut down. The minicomputer disk array performs each step in order to complete the shutdown according to the operating procedures.
After the shutdown, all the equipments are disassembled in the order from top to bottom. The off-duty personnel are professionals who have many years of construction experience in our company. All cables should be removed first when the rack is removed. All equipment should be handled gently to avoid unnecessary loss. After the equipment is removed from the rack, it will be transported by the porter to the destination room.
If you want to use a small cart and other transportation tools, you need to put cushions between the vehicle and the equipment to avoid excessive vibration during transportation, resulting in loose equipment accessories.
4) Equipment rack
The equipment rack is operated in the opposite order.
The shelves should be placed according to the layout of the cabinets designed by both parties in advance. The layout drawings need to be designed reasonably, save space, and be easy to maintain and beautiful.

7. Detailed ip address allocation table
8. Ensure that the equipment needed for the relocation is in place before the relocation and construction
9. Classification and statistics of equipment
The equipment includes UPS, patch panels, core switches, servers, firewalls, storage devices, etc. We provide further detailed device statistics for the equipment statistics currently involved in the equipment room, including equipment model, configuration, network, etc. Before the relocation, the corresponding form record document is given, the relevant auxiliary equipment accessories are determined, and the detailed record document is also required.
2. The relocation party is ready to work
1. Equipped with the equipment and tools needed for the relocation process.
2. Personnel are in place, identify the people and assign the tasks of each person.
3. Check the relocation equipment according to the equipment provided by the relocated party.
4. Confirm the layout of the device
After the basic design of the new equipment room is completed, we need to plan the placement of each cabinet and each network equipment in advance. The specific size of the machine can be measured in advance, and then the specific position of the machine can be planned on site to strive for the most reasonable and full use of the effective space of the machine room. Here you need to pay attention to the problem: if you need to expand the cabinet, put the data information points of the integrated wiring on the distribution frame in advance, so that if the network equipment such as the switch router is moved over and the jumper is installed, the network will be Can be used normally.
Three equipment testing
1. Comprehensive prevention of static electricity Although the computer works on electricity, static electricity can cause fatal damage to the computer, especially if it causes permanent damage to the motherboard chip. There are many reasons for static electricity: various power supply devices may generate static electricity, computer CRT displays may generate static electricity, and mobile phones and walkie-talkies in operation may generate a large amount of static electricity in the surrounding space. This requires us to pay special attention to static electricity interference and comprehensive prevention.
Try to make the grounding of the server and its peripherals as good as possible.
If the equipment is not grounded, when it is necessary to touch the board inside, it should be discharged with a grounding conductor or other discharge facility.
When you operate the device, you can touch the metal outside the chassis to remove the static electricity you carry. Ensure that the layout inside the chassis is reasonable. Generally speaking, the layout of the components inside the server chassis and the space design are scientifically arranged, and the combination of each other is compact but not messy. We must maintain this layout when adding and uninstalling the server device. effect. Note: There should be a considerable amount of reserved space inside the chassis to form a reasonable “duct”. This is because the CPU is not only the only heat source, but also high-speed hard disks, CD players, various chips and boards. Heat is generated in a small space, so the air inside the chassis must be able to flow sufficiently when the fan is turned.
2. The server restarts correctly.
Shutdown operation:
Close the operating system;
Turn off the power of the host;
Turn off the peripheral power supply;
Turn off the power of other devices and the power of the cabinet;
Turn off the main power.
Boot operation:
Turn on the main power supply;
Turn on the power of the computer cabinet;
Turn on the power of the external device;
After the external device self-test is completed, the host power is finally turned on.
Power on the machine, if the machine can start, the system is in good condition; if there is a problem after powering up, it means that the system has problems before the relocation, not caused during the relocation process. The relocation party is not responsible for it.
3. UPS power supply restarts correctly
The order of properly turning off the UPS power supply should be: first turn off the load connected to the output of the UPS power supply one by one, then turn off the power switch on the power control cabinet.
Open the correct order of the UPS power supply: Be careful not to touch the magnetic material during the relocation process. The correct switch steps Generally, the correct sequence for turning on the UPS power supply should be: first check the power polarity of the input end of the UPS power supply and the power supply of the mains power supply line. Whether the polarity connection is consistent, and then check whether the total power of the load connected to the UPS power supply is within the rated power of the UPS power supply; after satisfying the above conditions, turn on the power switch on the UPS power control cabinet to let the utility power The battery pack in the UPS is powered. After a period of time, the power switch of the load is turned on one by one. This ensures the load current and does not cause excessive impact on the internal power supply line of the UPS power supply, thereby effectively ensuring that the UPS power supply is not protected. internal injury.
Restart the power supply. If it can be started, the equipment is in good condition. If the operation is not normal, it is not caused during the relocation process. The relocation party is not responsible for it.

2. Disassembly and cleaning principle of the server: first turn off all the server workstations, turn off the power equipment such as the switch router, then turn off the total power supply, and finally remove the server.
Hard disk: The server hard disk is the data warehouse of the server, and all software and user data are stored here. For the user, the hard disk data stored on the server is the most valuable, so the reliability of the hard disk is very important. Pay special attention to the hard disk order in the server disk array during the disassembly and assembly of the server. If 10 hard disks are used as the array, at the time of initialization, the 10 hard disks should be sequentially placed in the disk array, which are divided into first, second, and tenth hard disks. If the disk array has sequential requirements, the hard disk must be inserted back into the disk array in the original placement order. Otherwise, the data may be inconsistent and the data may be lost due to the hard disk order.
The disassembly and assembly of the CPU requires attention to the following points: The bottom of the CPU is the core part consisting of dense integrated circuits. These small pins are easily deformed by extrusion, and if one of these small pins is bent, the CPU will not work properly. must be careful. The CPU socket of the motherboard and the side of the CPU with the small pin are exactly matched, so as long as the direction is correct when inserted, the CPU can be inserted into the motherboard with a single push. Don't use a lot of effort. If the CPU doesn't plug in, it's a problem with the direction of insertion. If the orientation is not correct when installing the CPU fan, it cannot be installed. Therefore, as with the CPU, do not use too much force, excessive force will cause excessive pressure between the motherboard and the CPU and cause damage.
When the cable is connected, the device connected through the cable should be powered off. That is, the power of the device should be turned off before the cable is connected. Otherwise, if the cable is connected with power, it may cause unpredictable damage to the equipment.
When the server board is added to the server board, be sure to select the angle when inserting the slot, and the power is even, so as not to damage the board or slot.
The motherboard should be more careful with the operation of the motherboard. The installation must be stable and prevent the motherboard from being deformed to avoid damage to the electronic circuit on the motherboard.
Open the casing to clean the dust on the inner surface of the servo. For large areas of dust on the inner surface of the server, use a dry cloth to spray with a professional cleaning solution. The cloth should be as dry as possible and should be dried after wiping. All plugs and sockets, expansion slots, memory slots and boards should not be wiped with water. You can also use a brush or blow off dust.
3. Host disassembly cleaning principle:
Turn off the system, disconnect the system power, and disassemble it from each cabinet into a removable part.
Before opening the case, your hands should touch the ground or the wall to release static electricity from your body. Maintain a certain humidity, air drying is also prone to static electricity, ideal humidity should be 40% -60%;

Cleaning the memory and strip memory strips and various adapter cards involves dusting and cleaning the gold fingers on the board. You can use a brush or blow off dust. You can also use an eraser to wipe off the dust, oil or oxide layer on the surface of the gold finger. You can't use sandpaper to wipe the gold finger, otherwise it will damage the extremely thin coating.
4. Cleaning principle of UPS power supply:
The order of properly closing the UPS power supply should be: first turn off the load connected to the output of the UPS power supply one by one, then turn off the power switch on the power control cabinet.
We need to pay attention to the cleaning of the UPS: Do not touch the magnetic material during the cleaning process?
Master the situation of UPS, and strive to make every cable have a heart, all the configuration, each interface must be clear, battery, cable must be labeled. When labeling equipment, it is generally the method of attaching the equipment nameplate, and the cable adopts a special identification ring. The planning of equipment labels is generally formulated by each unit. There is no uniform standard. Here we can consider numbering according to the type, function and area of the equipment. Each machine must be labeled before moving, especially for multi-connected machines. Each wiring connection is labeled and corresponds to the other end of the wiring.
Open the casing to clean the dust on the inner surface of the servo. For large areas of dust on the inner surface of the server, use a dry cloth to spray with a professional cleaning solution. The cloth should be as dry as possible and should be dried after wiping. All kinds of plugs and sockets, and boards should not be wiped with water. You can also use a brush or blow off dust.
Because all equipment will age after prolonged use, all equipment will be reinstalled after the correct equipment cleaning work is completed. If the power is turned on, if the equipment can be started, if the equipment is in good condition, if the operation is not normal, it is not caused during the relocation process. The relocation party is not responsible for it.
Five equipment relocation and installation
1. Equipment relocation sequence
Generally speaking, the order of equipment relocation is: server system, UPS, communication system, then network equipment, terminal equipment, and so on. Of course, you can also consider moving the equipment that does not affect the daily business to the new building, such as some monitors, terminals, mainframes, power cords, etc.
2. Relocation of equipment
After all equipment is cleaned, assembled, and tested, all equipment is boxed, reinforced, and protected against collision. Loading to the destination.
Equipment installation
Connect all devices correctly according to network planning.
Six post-relocation work
1. When placing the UPS in the new equipment room, pay attention to it: Weight bearing: When the UPS is configured for long delay, the battery may be heavy. In this case, the floor load should be considered. Space size: When the UPS is to be maintained, the engineering personnel have certain space for implementation. Grounding: There is a good grounding system, the general grounding resistance should be less than 5 ohms
2. When placing the server in the new computer room, please pay attention: when we put the server on the rack and do physical connection, we need to open the server to check whether the data is damaged and related. The setting of the software. In general, the work to be done roughly includes the following items:
1. Recovery of the server status to see if data loss or damage has occurred. If there is damage to this data, don't be afraid! We should restore the data before the relocation.
2. Perform the adjustment of the corresponding IP address.
3. Make adjustments to the relevant DNS settings.
4. Make adjustments to related VLAN settings
5. Perform adjustments to related software.
6. Conduct a test of the entire network server.
7. All servers are restarted to see if the speed and quality of the server are up to standard.
8. Acceptance and carry out relevant log records.
In order to ensure the normal operation of the network, our company will preferentially relocate the four servers in the central computer room within two working days.
Part 5: Computer room relocation plan
In order to ensure the safe, reliable and rapid relocation of equipment, our company has formulated the following relocation plan:
1) Professional engineers understand the current status of the user's current computer room and the specific requirements after the relocation. Fully consider the various situations that may occur during the implementation process, and customize the detailed feasibility of the migration implementation plan to minimize the impact of the computer room migration work on users;
2) Draw the physical layout diagram, connection diagram and cable number diagram before and after the relocation. Can be classified into multiple systems according to user conditions;
3) 所有圖紙整理成冊，並按照用戶意見，制訂出詳細的搬遷日程表：
日程表包括如下內容：
日期工作計畫完成情況出現問題解決方法用戶簽字：日程表需用戶簽字認可後方可進行正式搬遷工作
4) 搬遷工作步驟：
繪製圖紙：詳細對比辦公室搬遷前後的情況;
系統備份：分系統的數據備份，可使用光碟或外接磁碟存儲櫃進行備份;
備份後的數據形成的數據光碟，當天必須交給用戶的制定管理人進行保管，並簽字認可，保證所有數據不外泄露;
備份同時可以進行按圖紙，在設備的顯著位置貼編號，保證在搬遷時不被刮落;
設備保潔處理、加固處理、外包裝裝箱處理;
在用戶的指導下，關閉系統、斷開系統電源、從各機櫃進行拆卸成可搬遷的部分;
分系統順序搬遷到新機房，按事先確定的位置進行初步放置，待最終調試結束後固化安置;
設備上架安裝;
設備按關機的倒序進行開機調試;;
分系統調試;;
全系統聯調;;
系統機櫃最終固定;
技術指標的詳細恢復。
