Support for RAID Storage Configurations

Using the on-board SAS controller, you can set up hardware RAID 1 (mirroring) and
hardware RAID 0 (striping) configurations for any pair of internal hard drives,
providing a high-performance solution for hard drive mirroring.
Additional RAID levels are supported by installing the StorageTek SAS HBA
(internal PCIe card). This option requires a different set of internal cables.
By attaching one or more external storage devices to the SPARC Enterprise T5120 and
T5220 servers, you can use a redundant array of independent drives (RAID) software
application such as Solstice DiskSuite or VERITAS Volume Manager
system drive storage in a variety of different RAID levels.
