Configuring storage environments
IBM® Storage Protect Snapshot requires the connection and configuration information for all storage devices where data is to be protected. For IBM System Storage® DS8000® environments and IBM System Storage SAN Volume Controller with static target allocation, information on the associated volumes is also required.
IBM Storage Protect Snapshot organizes information on storage hardware in device classes. A device class is a representation of a specific storage device with its connection information and related configuration. There must be a separate DEVICE_CLASS defined for each storage device. If the same storage device is used with various functions and configurations, a separate device class must be defined for each configuration. An example of a different function, can be running full and incremental backups on different days of the week.
Device classes are documented as DEVICE_CLASS sections in the IBM Storage Protect Snapshot profile. Parameters in a DEVICE_CLASS section describe the characteristics of a storage device. Therefore, they are independent of the protected application, but different parameters are required for the various types of supported storage hardware.
Each DEVICE_CLASS can have specific version retention that is controlled through the profile parameter MAX_VERSIONS, which is set during configuration. For more information about DEVICE_CLASS version control with MAX_VERSIONS parameter, see Device class backup version retention.
Not all of the configuration topics are applicable to each storage system. For a list of storage environments and their associated configuration topics, see the following table.
| Storage environment | Topics |
|---|---|
| IBM System Storage DS8000 | Configuring the CIM adapter for SP 800-131A compliant encryption |
| IBM System Storage SAN Volume Controller or IBM Storwize family with dynamic target set allocation | Configuring Storwize family and SAN Volume Controller dynamic target allocation (SVCDTA) |
| IBM System Storage SAN Volume Controller or IBM Storwize family with static target set allocation | Configuring the CIM adapter for SP 800-131A compliant encryption |
| IBM XIV® Storage System |
