Disk I/O Tuning

Chapter 4: RAID Setup For SCSI

Figure 4-4: Stripe Vertically Down Trays

Several companies offer pre-built arrays, among them are EMC, Hitachi, Compaq (now HP) and IBM Shark. Let's look at what they have to offer.

EMC Storage Arrays

The EMC Clariion provides a redundant architecture allowing multiple paths to each disk in the array. Figure 4-5 shows this architecture. Notice the two storage processors, mirrored caches, CPU and fibre controllers. This redundancy of components allows multiple paths and high performance.  The Clariion ranges from the CX300 to the CX700 series and up to 58.4 terabytes of storage.
