Multiple Connections per Session
The Linux SCSI Target Wiki
MC/S is an acronymn for Multiple iSCSI Connections per iSCSI Session.
Core-iscsi Interopt - STATUS - STABLE
Open-iscsi Interopt - STATUS - NOT SUPPORTED
The following items as defined by RFC-3720 for MC/S support are:
1) Add additional connections on the fly (non-leading login) 2) Remove connections on the fly (explict logout) 3) Remove connections on the fly on a different connection (different CID explict logout)
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 SCSI Initiator Port -> SCSI Target Port as defined by the SCSI Architecture Model
