Support For Raid Storage Configurations; Error Correction And Parity Checking - Fujitsu SPARC ENTERPRISE T5120 Overview Manual

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.

Error Correction and Parity Checking

The UltraSPARC T2 multicore processor provides parity protection on its internal
cache memories, including tag parity and data parity on the D-cache and I-cache. The
internal L2 cache has parity protection on the tags, and ECC protection on the data.
