Selecting a RAID Level by Size of Pool Selecting a RAID Level by Size of Pool Use this table to select a RAID level based on the number of disk drives in your pool. Number of Disk Drives in Pool Possible RAID Levels One Two Three or more Four or more Six or more Eight or more Simple volume RAID 0 or RAID 1 RAID 0, RAID 1E, or RAID 5 RAID 0, RAID 6, or RAID 10 RAID 0 or RAID 50 RAID 0 or RAID 60 Expanding Pool Capacity Using Adaptec Storage Manager, you can expand the capacity of a pool by adding one or more disk drives (see page 90). You can expand pools with any of these RAID levels: RAID 0, RAID 5, RAID 6. Changing from One RAID Level to Another Using Adaptec Storage Manager, you can change a pool's RAID level. Changing a pool's RAID level may also increase its capacity. 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 You can also migrate from RAID 1 or RAID 5 to RAID 0. If the pool has a spare drive associated with it, the RAID 0 pool retains the spare drive. Note Migrations that do not involve a change in RAID level are also supported in RAID 0, RAID 1, RAID 5, and RAID 6. See "Expanding Pool Capacity" on page 200 for more information. 200 Snap Server 700i Series User's Guide
