Have You Ever Encountered the Following Difficulties. . . Migration duration longer than specified The migration process lasts a long time due to the huge data amount. Moreover, the migration duration is also subject to various software and Longer service shutdown duration Data migration requires that applications be stopped. If the migration cannot be completed within the specified duration, the enterprise will suffer serious inconvenience and loss. Decrease of customer satisfaction, causing enormous loss The enterprise fails to run businesses normally, bringing down the customer satisfactory and brand loyalty, reducing the enterprise's revenue, and impeding the enterprise's development. hardware factors. Data migration is a large project. During the project, any small mistake may result in enormous loss! HUAWEI TECHNOLOGIES CO. , LTD. Huawei Confidential

Causes for Data Migration As the enterprise IT environment changes according to the business demand, an enterprise usually has the following requirements: • Transfers the data of the IT system to the newly purchased storage device or the central storage device. • Relocates the data center. • … As shown in the figure on the left, replacement of devices and changes of the application system requirements are the main factors that cause the data migration service requirements. They cause 65% of the data migration service requirements. Diagram of data migration service requirements HUAWEI TECHNOLOGIES CO. , LTD. Huawei Confidential

Data Migration Based on the VIS System l l l Change the system topology, that is, add Huawei virtual intelligent storage (VIS) system to the customer's application system. The connection mode changes from "server-storage" to "server-VISstorage. " Restart the application system after the VIS system is added to the network. Connect the migration target array to the VIS system, and map LUNs that are originally allocated for servers to the VIS system. Perform mirroring between the source storage array and the target storage array on the VIS system. After the mirroring process is complete, break the logical connection between the source storage array and the VIS system. The target storage array provides storage space to the application system through the VIS system. Restore the original system topology. HUAWEI TECHNOLOGIES CO. , LTD.

Data Migration Based on LUN Copy l l l Connect Huawei Ocean. Stor SAN storage array with the LUN copy feature to the customer's original storage array over Fibre Channel or i. SCSI. Add mapping information of the target storage array on the original storage array, so that Huawei SAN storage array can identify the migration source LUN. On Huawei SAN storage array, use the LUN copy feature to copy data from the original storage array until data on both arrays becomes consistent. Shut down the application system. Then, map the target LUN on Huawei storage array to the server, and meanwhile disconnect the original array from the server. This operation interrupts the customer's application system (the shutdown does not exceed 30 minutes). Start the application system. Data migration is complete. HUAWEI TECHNOLOGIES CO. , LTD.

Data Migration for China Mobile Music Platform Countermeasures suggested by Huawei Challenges 1. Critical service with explosive data China Mobile music platform carries the music and tone download service on the 12530 Web site. This critical service brings mass data that is still exploding to the platform. Currently, the data amount is 35 TB, and is estimated to reach 200 TB as the service develops. 2. Heavy workload and long maintenance duration, affecting service operation The original application system works in dual-system hot backup mode, so only one host works, barely satisfying the service requirements. All data is stored on one volume. Each time this volume is mounted after hardware maintenance, the system spends more than five hours on the automatic fsck check of the volume. More worse, the duration becomes longer as the data increases. This disturbs the service operation. Data migration project with the largest amount of data on a single LUN HUAWEI TECHNOLOGIES CO. , LTD. 1. Constructing active-active file systems to achieve load balancing and address the fsck problem Huawei N 8000 NAS system changes the work mode of the customer's cluster from hot backup to active, so that four servers simultaneously work, achieving load balancing and allowing for further service development. In addition, the four servers are mounted with active-active volumes that support data synchronization and sharply shorten the fsck check duration. 2. Using Vx. VM volume mirroring to implement mass data migration Symantec Vx. VM volume mirroring function implements online migration of the 35 TB data, while protecting the service continuity to the maximum. The service is interrupted by only mirror initialization and mirror splitting, both of which last a very short time. Data synchronization does not interrupt the service. The success of the music platform project eliminates the risks of the original platform and greatly improves the system processing capability and reliability. This helps China Mobile to fulfill the goal of constructing a world-class wireless music download platform. 　　　　— China Mobile West Zone Service Support Center Huawei Confidential
