2.4 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 JBOD (Just a Bunch of Drives), allowing you to connect standalone disk drives (such as a system disk) to the controller without making them mem- bers of a RAID set.

∙Each RAID set can be partitioned into smaller redundancy groups.

∙Any drive may be designated as a spare. Spares are global, meaning that in the event of a drive failure, the controller will search for the first available spare on any channel or SCSI ID and automatically begin rebuilding the failed drive’s data.

∙All configuration and monitoring of RAIDsets accomplished via SWCC with software platform kit.
