See SWL. MOF Managed Object Format file. Morphed WWN In a Brocade SAN, ADs are treated as fabrics; since switches cannot be part of two fabrics, but they can be part of two ADs, their WWNs are "morphed" so that they appear as unique entities in different fabrics. MRK Mark Primitive Signal. Used only in Arbitrated Loop, it is transmitted by an L_Port for synchronization and is vendor specific. MS Management Server. Allows a SAN management application to retrieve information and administer the fabric and interconnected elements, such as switches, servers, and storage devices; located at the FC well-known address FFFFFAh. MTBF Mean Time Between Failures. An expression of time indicating the longevity of a device. Multicast A restricted broadcast to a subset of the N_Ports on the network. Multimode (MMF) A fiber optic cabling specification that allows up to 500-m distances between devices. Multiprotocol Router A device that enables Brocade multiprotocol routing services. Multiprotocol Routing Services Optionally licensed software bundle available on certain Brocade platforms, such as the Multiprotocol Router, that includes the FC-FC Routing Service, the iSCSI Gateway Service, and the FCIP Tunneling Service. Multiprotocol SAN Routing Services (MSRS) An optionally licensed software bundle available on certain Brocade platforms, such as the Brocade AP7420, that includes the Fibre Channel Routing Service, iSCSI Gateway Service, and FCIP Tunneling Service. N N_Port A Fibre Channel port in a fabric or point-to-point connection. Name Server or Service A switch service that stores names, addresses, and attributes for up to 15 minutes and provides them as required to other devices in the fabric; also known as "Simple Name Server (SNS)" or "directory service."
