Advanced RAID organization for ensuring data access even during a drive enclosure failure
In ETERNUS AF/ETERNUS DX, each member disk drive of a RAID group is located in a different Drive Enclosure. This keeps the RAID group accessible even when one whole Drive Enclosure becomes unusable.
In addition, with support of RAID6 (double parity), two disk drive failures occurring in the same RAID group can be recovered. This ensures exceptional reliability.
The figure shown below is an image. The configuration will differ depending on the product.
