21.1 Functional Overview

This product realizes storage management for open systems and consists of the following three solutions:

High-speed backup (round-the-clock support)

Data can be backed up at high speed by using the hardware [advanced copy function (OPC, EC)] of the Fujitsu disk array unit (ETERNUS3000, GR720, GR730, GR740). Since the advanced copy function is a high-speed data copy function that is not dependent on the volume of data, a constant, high-speed backup time can be always maintained even when the amount of data to be backed up increases. Thus, the backup time does not increase even when the data quantity increases.

By linking this solution with the following DBMS, high-speed backup can be done without stopping the job:

For those jobs that are constructed using a database other than the above or a general file system, the job non-stop time required for the backup is significantly reduced compared with that in the past.

Database backup without stopping the job

Oracle and SymfoWARE database backup can both be done without stopping the job by using ETERNUS SF AdvancedCopy Manager.

When combined with Global Disk Services, ETERNUS SF AdvancedCopy Manager can be used to perform backup without stopping Global Disk Services, even in the mirror volume (SDX object) environment.

High-speed replication

By using the hardware [advanced copy function (OPC, EC)] of the Fujitsu disk array unit (ETERNUS3000, GR720, GR730, GR740), the data can be used for various purposes and a data replication (copy) can be collected to guard against accidental data destruction.

A remote disk array unit in the SAN environment is also available for storing the replication (copy) for the purpose of restoring the data after a catastrophic failure.
