The purpose of this paper is to demonstrate that moving from a shared back-end bus structure to a switch-based back-end structure in the design of RAID servers or file servers can significantly enhance the performance and availability of these systems.
It discusses design issues within the context of modular RAID servers, why incorporating a back-end switch into the design of a storage server can lead to significant performance and availability improvements and a unique switching technology, and a family of switching products. (May 2002)
