RAID Functions
This section explains the points to note before configuring a system using the
ETERNUS AF.
Supported RAID
The ETERNUS AF supports the following RAID levels.
•
RAID0 (striping)
•
RAID1 (mirroring)
•
RAID1+0 (striping of pairs of drives for mirroring)
•
RAID5 (striping with distributed parity)
•
RAID5+0 (double striping with distributed parity)
•
RAID6 (striping with double distributed parity)
•
RAID6-FR (provides the high speed rebuild function, and striping with double distributed parity)
Remember that a RAID0 configuration is not redundant. This means that if a RAID0 drive fails, the data will
not be recoverable.
This section explains the concepts and purposes (RAID level selection criteria) of the supported RAID levels.
