RAID technology has matured to the point where RAID products and components of RAID subsystems such as disks and cache controllers are not new from a performance modeling standpoint. Tools and algorithms for testing RAID components are widely available, and these tools can assess RAID performance in the context of the overall network. A RAID subsystem typically stores the data accessbile on one logical device over several physical devices, a process called disk striping or disk interleaving. Different methods of disk interleaving are known as RAID levels one through five. The RAID levels ar
