Flexible RAID Set Configuration
In addition to its flexible hardware design, the controller’s firmware offers the
user the flexibility to configure RAID sets in several different ways:
■
RAID sets can comprise drives from any drive channel and SCSI ID.
■
A RAID set can contain all the drives connected to the controller, a
single drive, or any number of drives in between.
■
The controller supports RAID Levels 0, 1, 0+1, 4, and 5. It also supports
Just a Bunch of Drives (JBOD), allowing you to connect standalone disk
drives (such as a system disk) to the controller without making them
members of a RAID set.
■
Each RAID set can be partitioned into smaller redundancy groups.
