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 some ETERNUS AF and ETERNUS DX are able to deploy drives where RAID 6 and 5 arrays are deployed across separate drive enclosures (DE) for improved reliability. (Learn more)

Furthermore, ETERNUS AF and ETERNUS DX S4/S3 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)
