RAID Lite's eight RAID ranks (LUNs) can consist of up to seven disk drives on five independent SCSI busses. The wide drive arrays provide a high-degree of parallelism which translates to better performance. For example, for a six drive RAID set configured for RAID level 5, up to five RAID drives can read data concurrently. This results in measurably better response time than narrow five drive arrays, and many times the read performance of a single drive.
Each of RAID Lite's eight ranks can be configured with a different RAID level. This allows RAID Lite to simultaneously provide great performance and fault tolerance to four different applications. One rank can be configured for RAID level 0 If you need blazing speed for a read-intensive application. Another rank can be set-up with RAID level 5 if you need the added capability to survive a drive failure. And still another two ranks can be configured for RAID level 1 to ensure high data reliability.
