Creating and Modifying Pools Adding Capacity to a Pool You can add disk drives to an existing pool to expand its capacity without changing its RAID level. When you expand a pool, stored data is distributed (or migrated) across all the original and new disk drives. You can expand pools with any of these RAID levels: RAID 0, RAID 5, RAID 6, or RAID 1E. The maximum supported size for a pool is 512 TB. To increase the capacity of a pool: 1 In the Logical Devices View, select the pool you want. 2 In the Actions menu, click Expand or migrate pool. The wizard opens to the Choose RAID Level window. (Don't change the RAID level.) 3 Click Next. The Modify Pool window opens. 4 Select available disk drives to add to the pool. Unavailable disk drives are indicated by blue check marks. 5 Click Next, then review the pool settings. 6 Click Apply, then click Yes to expand the pool. The capacity of the pool is increased. You can use the new storage space right away. Changing a Pool's RAID Level If your requirements change, you can change the RAID level of an existing pool. You might want to do this to increase the capacity or performance of a pool, add redundancy to a pool, or to make disk drive space available for other uses. When you change the RAID level of an existing pool, stored data is migrated across existing and new disk drives. This table lists supported migrations: From RAID Level To RAID Level Simple Volume RAID 0 RAID 1 RAID 5 RAID 6 RAID 10 RAID 1 RAID 5 or RAID 10 Simple Volume, RAID 5, or RAID 10 RAID 0, RAID 10, or RAID 6 RAID 5 RAID 0 or RAID 5 90 Snap Server 700i Series User's Guide
