Parity groups and volumes

When adding drives to increase LDEV free space, the free space can be increased in the storage system by configuring RAID. The storage systems support RAID 1, RAID 5, and RAID 6.

In one parity group, a maximum of 2,048 fixed-size volumes (FVs) and some free space is available. The maximum number of LDEVs in each storage system model is:

• VSP G800: maximum 16,384 LDEVs
• VSP G400, G600 or VSP F400, F600: maximum 4,096 LDEVs
• VSP G200 or VSP G100: maximum 2,048 LDEVs
• VSP G150: 16,384

  Configuring custom-sized provisioning involves creating and configuring custom-size volumes (CVs). CVs are created by dividing a fixed-sized volume (FV) into several smaller volumes of arbitrary sizes.
