Chapter 3: About Your RAID Controller ● 17 ● 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. Adding a Battery Backup Module This table shows the battery model supported by your Adaptec RAID controller.
