SCSI磁盘标准的架构与文档-LMLPHP

(*) This chart reflects the currently approved SCSI project family. T10 is responsible for all projects, except: IEEE is responsible for IEEE 1394; T11 responsible for Fibre Channel; Internet Engineering Task Force (IETF) is responsible for iSCSI and the Internet; the InfiniBand Trade Association is responsible for InfiniBand (tm); and the USB Implementers Forum, Inc. is responsible for the Universal Serial Bus (USB).

Note that the original third-generation SCSI standards used the name SCSI-3 to distinguish them from SCSI-2. Subsequent SCSI standards have dropped the '-3' from their names because it was cumbersome. So, when the SCSI-3 Architecture Model (SAM) was revised, it became the SCSI Architecture Model - 2 (SAM-2). While the individual components of the SCSI family continue to evolve, there is no SCSI-4 project envisioned.

About SCSI-2:

SCSI-2 is the predecessor to the SCSI-3 family of standards. It is a single standard containing all SCSI architecture layers for only the parallel interface. There is a companion standard for SCSI-2 called the SCSI-2 Common Access Method and SCSI Interface Module (CAM) that describes a layered software driver method for usage with SCSI-2. While most software drivers today do not exactly conform to CAM, they generally do follow its layered concepts:

SCSI-2 Small Computer System Interface - 2 [second generation of SCSI] 
CAM SCSI-2 Common Access Method and SCSI Interface Module [software layering standard]
