RAID 6

Index | Features | RAID 0 | RAID 1 | RAID 1+0 | RAID 2 | RAID 3 | RAID 4 | RAID 5 | RAID 5+0 | RAID 6 |


RAID 6 deploys two parity records to different disk drives (double parity) enabling two simultaneous disk drive failures in the same RAID group to be recovered.
RAID 6 where parity updates are allocated separately across multiple disks, as well as RAID 5, are able to implement multiple write orders at the same time. This feature ensures higher performance when compared to RAID 4 technology.

And ETERNUS DX8000 series and ETERNUS8000 are able to deploy disk drives where RAID 6 and 5 arrays are deployed across separate drive enclosures (DE) for improved reliability. (Learn more)

Furthermore, ETERNUS DX S3 series features high-speed rebuild function using double parity named "Fast recovery". This function shortens the rebuild time and avoids the risk of interruption of business operations. (Learn more)
