15 Table 15-1 iSCSI Gateway Services Terminology (Continued) Term Definition iSCSI session An iSCSI session is the basic communication "pipe" from an iSCSI initiator to an iSCSI target. A session is a group of TCP/IP connections that link an initiator with a target (loosely equivalent to a SCSI I-T nexus). LUN mapping Logical Unit Number mapping. The mapping of the virtual iSCSI target and the physical Fibre Channel target One frontend LUN (VT LUN) maps to a backend LUN (Fibre Channel LUN). The frontend LUN numbers can be different from the backend LUN numbers. Fibre Channel LUN The LUN identifier of the Fibre Channel target. VT LUN Virtual target LUN. The LUN identifier of the iSCSI virtual target. Fibre Channel virtual initiator (FC-VI) The iSCSI port looks like an F_Port to the rest of the system. There is one Fibre Channel virtual initiator per iSCSI. The Fibre Channel proxy initiator solution is used. FC-VI registers to the Name Server with its symbolic port name (PWWN) and node name (NWWN). The FC-VI in the Name Server entry is created irrespective of the host connectivity. discovery domain (DD) Created between and iSCSI host and iSCSI targets using their IQN for the purpose of iSCSI device access control. discovery domain set (DDSet) Created using DDs. Can be configured to enable or disable the configuration for the purpose of iSCSI device access control. CHAP authentication Authenticates the initiators against a list of user names and passwords with CHAP (Challenge Handshake Authentication Protocol) authentication in either one-way or mutual. IQN An iSCSI Qualified Name that indicates an iSCSI node name in a form that is of human readable notation using the following syntax: iqn.yyyy-mm.: GbE port Gigabit Ethernet port. Uses a copper CAT-5e cable for an IP connection to an RJ-45 copper connector. FC4-16IP has 8 ports of this type that support 1 Gbps speed. PDU Protocol Data Unit. A unit of data with a header and an optional data section.
