Raid 6 recommendations .

Publication Date:  2015-01-29 Views:  166 Downloads:  0

Issue Description

After running a toolkit test , customer received a warning saying that it is recommended to use Raid 6 configuration on Sata disks.


Actually this is not a bad advice. When using only Sata disks in a Raid group (which is another recommendation - use only one type of disk in a raid group) Raid 6 should be configured due to the high rate of failure for sata disks . Customer had configured Raid 5 on a group composed of Sata disks . Besides Raid 6 on Sata disks also a Hot Spare disk should be involved in this configuration to assure the system stability.
