Chapter 3: About Your RAID Controller 19

Advanced Data Protection Suite

Note: The following features are supported on Adaptec Series 5 and Series 6 controllers. Striped Mirrors are also supported on Series 2 and Series 6E controllers.

Copyback Hot Spare—You can use this feature to move data from a hot spare back to its original location after a failed disk drive is replaced.

Striped Mirror (RAID 1E)—A RAID 1 Enhanced array is similar to a RAID 1 array except that data is both mirrored and striped, and more disk drives can be included.

Hot Space (RAID 5EE)—A RAID 5EE array is similar to a RAID 5 array except that it includes a distributed spare and must be built from a minimum of four disk drives.

Dual Drive Failure Protection (RAID 6)—A RAID 6 array is similar to a RAID 5 array except that it includes two independent sets of parity data instead of one.

Dual Drive Failure Protection (RAID 60)—A RAID 60 array is similar to a RAID 50 array except that it includes four independent sets of parity data instead of two.
