Dell just released the new line of Dell/EqualLogic arrays. The PS6xxx comes in all traditional array forms as in SATA 7.2k RPM, SAS 10k, SAS 15k, and now Solid State Drives… The release also comes with a added support for Automatic RAID 5, RAID 6, RAID 10 and RAID 50 for all arrays including PS5500 and PS6500.

Raid 5,10 and 50 have been around a while on the EqualLogic Platform.
Raid 6 Details: RAID 6 (Striped set with dual distributed parity) extends the concept of RAID 5 to the use of 2 parity blocks per stripe (referred to as N+2). Given 16x 1 TB disks, a RAID 6 implementation would be able to host 14 TB of data and reserving 2 TB of space for parity. RAID 6 implementations can tolerate up to 2 drive failures at the same time without data loss.

For more information on these Raid Types please see this document on Dell EqualLogic’s website.
