Abstract

As storage environments and storage area networks (SANs) grow, enterprises increasingly have the need to extend data transfers beyond the confines of the enterprise over longer distances such as metropolitan area networks (MANs) and wide area networks (WANs) for disaster-recovery and business-continuity applications. By using virtual concatenation (VCAT), link capacity adjustment scheme (LCAS) and generic frame procedure(GFP), Next generation SONET/SDH can move SCSI commands and block-level data over long distances in an efficient and cost-effective manner. This paper analyses the limitation of traditional SONET/SDH for storage services and the new characteristics of Next generation SONET/SDH. The design approach and steps of GFP interface based SOPC are proposed, furthermore the architecture of SAN extension based on Next generation SONET/SDH is presented.
