Choosing the correct type of storage technology for IBM Spectrum Protect
Storage devices have different capacity and performance characteristics. These characteristics affect which devices are better for use with IBM Spectrum Protect.
Procedure
Review the following table to help you to choose the correct type of
storage technology for the storage resources that the server requires.
Storage technology type | Database | Active log | Archive log and archive failover log | Storage pools |
---|---|---|---|---|
Solid-state disk (SSD) | Place the database on SSD in the following circumstances:
|
If you place the IBM Spectrum Protect database on an SSD, as a best practice, place the active log on an SSD. If space is not available, use high-performance disk instead. | Save SSDs for use with the database and active log. The archive log and archive failover logs can be placed on slower storage technology types. | Save SSDs for use with the database and active log. Storage pools can be placed on slower storage technology types. |
High-performance disk with the following characteristics:
|
Use high-performance disks in the following circumstances:
Isolate the server database from its logs and storage pools, and from data for other applications. |
Use high-performance disks in the following circumstances:
For performance and availability, isolate the active log from the server database, archive logs, and storage pools. |
You can use high-performance disks for the archive log and archive failover logs. For availability, isolate these logs from the database and active log. | Use high-performance disks for storage pools in the following circumstances:
For performance and availability, isolate storage pool data from the server database and logs, and from data for other applications. |
Medium-performance or high-performance disk with the following characteristics:
|
If the disk system has a mix of disk technologies, use the faster disks for the database and active log. Isolate the server database from its logs and storage pools, and from data for other applications. | If the disk system has a mix of disk technologies, use the faster disks for the database and active log. For performance and availability, isolate the active log from the server database, archive logs, and storage pools. | You can use medium-performance or high-performance disk for the archive log and archive failover logs. For availability, isolate these logs from the database and active log. | Use medium-performance or high-performance disk for storage pools in the
following circumstances:
For performance and availability, isolate storage pool data from the server database and logs, and from data for other applications. |
SATA, network-attached storage | Do not use this storage for the database. Do not place the database on XIV storage systems. | Do not use this storage for the active log. | Use of this slower storage technology is acceptable because these logs are written once and infrequently read. | Use this slower storage technology in the following circumstances:
|
Tape and virtual tape | Use for long-term retention or if data is infrequently used. |
