Example configuration with Storwize V7000 systems

Edit online

The example illustrates how you can configure IBM Storwize V7000 systems for an IBM Storage Protect server. In this example, the server needs 2 TB for its database and 58 TB for its storage pool on disk.

The following components are used in the configuration:
  • One Storwize V7000 Disk Control Enclosure, which can hold 24 2.5-inch disk units
  • Three Storwize V7000 Disk Expansion Enclosures, each of which can hold 24 2.5-inch disk units
Together, these enclosures can hold up to 96 disk units. See the following table for the disk specifications and configuration. All disks are 2.5-inch disks.
Server storage requirement Disk capacity Disk speed and type Disk quantity RAID type RAID array quantity Usage
Database 300 GB 15k rpm SAS HDD 12 4 + P RAID 5 2 These disks provide space for the database on two 4 + P RAID 5 arrays, with two spare disks.

For optimal performance, use the Easy Tier® function with SSD disk units for the database. Use the Easy Tier function for the database only, not for the logs or the storage pool.

If you are using data deduplication, data replication, or both, either substitute SSD disk units for the database or add some SSD units and use the Easy Tier function.
Active log and archive log 300 GB 15k rpm SAS HDD 4 RAID 0 2 These disks provide space for the archive log and active log on two RAID 0 arrays. Spare disks are shared with the disks for the database.
Storage pool 900 GB 10k rpm SAS HDD 80 6 + P RAID 5 11 These disks provide space for a 58 TB storage pool. The disks are configured in eleven 6 + P RAID 5 arrays, with three spare disks.

If the throughput for the storage pool does not require the higher speed of the 10k rpm drives, you can use 7.2k rpm nearline-SAS HDD drives. Verify that the slower disks can meet throughput requirements.

If greater storage pool capacity is required, add more enclosures.
