Storage systems

A storage system is a hardware device that contains data storage. Copy Services Manager can control data replication within and between various storage systems.

To replicate data among storage systems that use Copy Services Manager, you must manually add a connection to each storage system in the Copy Services Manager configuration. You can then omit storage systems for which Copy Services Manager does not manage replication and omit storage systems that are being managed by another Copy Services Manager management server.

For redundancy, you can connect a single storage system by using a combination of direct, Hardware Management Console (HMC), and IBM® z/OS® connections.

You can use the following storage systems:

• IBM DS8000®
• Systems running IBM Spectrum® Virtualize
• Systems running IBM Spectrum Accelerate, including:
  • XIV®
  • FlashSystem A9000
  • FlashSystem A9000R

FlashSystem V840, FlashSystem V9000, FlashSystem 9100, FlashSystem 9200, and SAN Volume Controller systems can virtualize various storage systems. Although Copy Services Manager does not support all storage systems, you can manage other storage systems through a single FlashSystems/IBM Spectrum Virtualize or SAN Volume Controller cluster interface. Copy Services Manager connects directly to the FlashSystems/IBM Spectrum Virtualize or SAN Volume Controller clusters.

You can define a location for each storage system and for each site in a session. When you are adding copy sets to the session, only the storage systems whose location matches the location of the site are allowed for selection. This design ensures that a session relationship is not established in the wrong direction.
