ISO/IEC 14165-521:2009 Preview
Information technology -- Fibre Channel -- Part 521: Fabric application interface standard (FAIS)
ISO/IEC 14165-521 defines an application programming interface (API) by which a storage application may perform the functions of one or more SCSI Targets or Initiators, and control high-performance command/data forwarding and manipulation facilities. It describes a set of functions and data structures in the C language abstracting the details of the platform from the implementation of a storage management application. The series of fibre channel publications provides a general data transport vehicle for Upper Level Protocols (ULPs) such as Intelligent Peripheral Interface (IPI) and Small Computer System Interface (SCSI) command sets, the High-Performance Parallel Interface (HIPPI) data framing, IP (Internet Protocol) and others.
