Greater storage system availability and improved performance are high priorities for business IT managers. Multipathing is a fault tolerant technique where there is more than one physical path between the CPU in a computer system and its mass storage devices.

This paper discusses the benefits of current multipathing solutions and how the technology increases end-to-end redundancy and achieves storage availability and high performance when used with a RAID array.
