Enterprise Data Center is the master control center of the data information and business application system. It offers an integrated business support platform for an enterprise. In building the storage system of an en-terprise data center, many types of storage technologies and associated equipment will be provided for selection. Since the cost budget of information system building is limited in engineering and survey enterprises, it is always a challenge in the building of a data center to select a data storage system with large volume, flexible extensibility and high safety in a rational way. This article introduces how China Electronics Engineering Design Institute has devel-oped and built a practicable and reliable data storage system with high cost performance for centralized storage and backup management by the application of IP SAN storage infrastructure as well as the information system manage-ment platform development by itself.
