Internet Small Computer System Interface (iSCSI) SCSI Features Update

Abstract

Internet Small Computer System Interface (iSCSI) is a SCSI transport protocol that maps the SCSI family of protocols onto TCP/IP. The iSCSI protocol as specified in RFC 7143 (and as previously specified by the combination of RFC 3720 and RFC 5048) is based on the SAM-2 (SCSI Architecture Model -

Internet Small Computer System Interface (iSCSI) Protocol (Consolidated)

“…2) Specified iSCSIProtocolLevel as "1" in Section 13.24 and added a related normative reference to [RFC7144].…”

“…Values 9-12 are assigned in [RFC7144]. All other possible values for the Function field are unassigned.…”

“…As a responder or an originator in a negotiation of this key, an iSCSI implementation compliant to this document alone, without any future protocol extensions, MUST use this value as defined by [RFC7144].…”

Internet Small Computer System Interface (iSCSI) Extensions for the Remote Direct Memory Access (RDMA) Specification

“…Do not require any major changes to the SCSI Architecture Model [SAM5] and SCSI command set standards.…”

“…The iSCSI protocol ( [iSCSI]) is a mapping of the SCSI Architecture Model (see [SAM5] and [iSCSI-SAM]) over the TCP protocol. SCSI commands are carried by iSCSI requests, and SCSI responses and status are carried by iSCSI responses.…”
