MC/S is an acronymn for Multiple iSCSI Connections per iSCSI Session.

Overview

MC/S means creating multiple communication paths across TCP/SCTP or iSER & RCaP connections + RFC-3720 defined session-wide CmdSN ordering to ensure in-order delivery of tasks from an SCSI Initiator Port to an SCSI Target Port as defined by the SCSI Architecture Model, in which iSCSI provides the SCSI transport.

Linux Compatibility

• Core-iscsi Interopt: supported, stable
• Linux-iscsi Interopt: not supported
• Open-iscsi Interopt: not supported

The requirements as defined by RFC-3720 for non ERL dependent MC/S support are not limited to the following:

• Add additional connections on the fly with active+inactive IO (non-leading login)
• Remove connections on the fly with active+inactive IO (explict logout)
• Remove connections on the fly on a different connection with active+inactive IO (different CID explict logout)
• Restart session+connections during single connection failure (session reinstatement)
• Multiple connection sessions to the same and different network portals (iSCSI trunking)
