EMC: planning and implementation of bank data center relocation

With the in-depth development of bank datasets, various business data is centrally processed. As the business continues to expand, we may need to expand the old data center and build a new center. In this case, we need to migrate the data center. In fact, for larger data centers, disaster recovery technology is often used to migrate data and the original data center is used as the backup center.

How can we ensure that data is not lost during data center migration? How can we ensure that the business system does not pause during data center migration? These are all problems for our bank.

Based on the EMC srdf technology, this article takes the migration of the new and old data centers and the disaster recovery system of the Xiamen Branch of China Construction Bank as an example to discuss the planning, design and implementation of the data migration and relocation scheme of the data center.

I. Data center migration background

Bank data centers have the following features: business concentration, data concentration, massive data capacity (at least TB), large business volume, high business continuity requirements, and high availability of key business data. With the centralized bank data, the old data center cannot meet the needs of business system development due to capacity, performance, operating environment and other restrictions. At this time, banks may establish a new data center. Because of the business continuity requirements of 24x7 and the importance of customer data, ensuring business continuity is the core requirement of data center migration. The high reliability of data migration is the key to the success or failure of data center migration. The impact on services during data migration and the guarantee of data integrity during migration are the basis for selection of Migration Technology and solution design.

With the development of various business systems of xiamen construction bank, the original computing center data center has been unable to meet the requirements of more and more business systems for the central operating environment, and the system expansion is greatly limited. With the use of the new branch business building and the construction of the new center data center in the new building, Xiamen Construction Bank needs to move the original data center to the new business building.

The host system of the original data center of xiamen construction bank is basically based on the ibm rs/6000 host and emcstorage platform. The main banking system of Xiamen Construction Bank includes core business such as public, savings, and bank cards, as well as agency and intermediate business. The application system is built based on the TUXEDO middleware and database systems such as INFORMIX and DB2. The production data is centrally stored in an EMC symmetrix 3830 compaction machine with an available space of about 600 GB.

Xiamen Construction Bank selects an EMC symmetrix 8530 host as the primary storage device in the new data center, and also buys software such as srdf, timefinder, powerpath, and ECC and uses srdf for data migration, this provides necessary conditions for data migration and system migration using srdf. From the perspective of saving money, the host systems of the new data center will not be purchased separately, and all will be relocated from the old data center.
This article focuses on data migration and physical migration of devices.
