Fibre Channel doubles speeds of SANS

摘要

The 4G bit/sec Fibre Channel standard boosts the performance of storage-area networks by doubling speed while maintaining backward-compatibility with 1G and 2G bit/sec systems. In addition, 4G bit/sec storage hardware will be available later this year at a cost comparable to today's 2G bit/sec products. A task group at the Accredited Standards Committee developed the 4G bit/sec Fibre Channel link specifications for backplane connection between disk drives and drive controllers in storage arrays. ANSI approved the specification in 2002 as Fibre Channel-Physical Interfaces (FC-PI). Last May the Fibre Channel Industry Association recommended 4G bit/sec Fibre Channel for switched fabric networks that connect these storage arrays to servers in the corporate data center.
