RAID technology enables the construction of a logical volume, made up of several physical disks, in order to provide data redundancy, increased performance, or both. The Sun SPARC Enterprise T5120 and T5220 server’s on-board disk controller supports both RAID 0 (striping) and RAID 1 (mirroring) volumes using the Solaris OS raidctl utility.
To configure and use RAID disk volumes on the Sun SPARC Enterprise T5120 and T5220 servers, you must install the appropriate patches. For the latest information about patches, see the product notes for your system.
Volume migration (relocating all RAID volume disk members from one Sun SPARC T5120 or T5220 chassis) is not supported. If you must perform this operation, contact your service provider.
The Sun SPARC Enterprise T5120 and T5220 servers can also be configured with a Sun StorageTek SAS RAID HBA. To manage RAID volumes on servers configured with these controllers, see the Sun StorageTek RAID Manager’s Software User’s Guide.
