MSRS MTBF multicast multimode N_Port Name Server NAS NDMP NIC NL_Port node node count node name Nonparticipating Mode NOS NR_Port NS NSCAM Nx_Port OFC Multi-protocol SAN Routing Services. An optionally licensed software bundle available on certain HP platforms, such as the HP StorageWorks Multi-protocol Router, which includes the Fibre Channel Routing Service, the iSCSI Gateway Service, and the FCIP Tunneling Service. Mean time between failures. The average time a component works without failure. This average is calculated by dividing the number of failures by the hours under observation. The transmission of data from a single source to multiple specified N_Ports (as opposed to all the ports on the network). See also broadcast and unicast. A fiber optic cabling specification that allows up to 500 meters between devices. Node port. A port on a node that can connect to a Fibre Channel port or to another N_Port in a point-to-point connection. See also NL_Port and Nx_Port. See Simple Name Server Network-attached storage. A disk array connected to a controller that provides access via a LAN. Network Data Management Protocol. Used for tape backup without using server resources. Network interconnect card. A printed circuit board that plugs into the bus of both the client machines and servers in a network. Controls the transmission and reception of data at the data link level. Also called a Network Interface Card and a network adapter. Node loop port. A node port that has arbitrated-loop capabilities. Used to connect an equipment port to the fabric in a loop configuration through an FL_Port. See also N_Port, Nx_Port, private NL_Port, and public NL_Port. A Fibre Channel device that contains an N_Port or NL_Port. The number of nodes attached to a fabric. The unique identifier for a node, which is communicated during login and port discovery. A mode in which an L_Port in a loop is inactive and cannot arbitrate or send frames but can retransmit received transmissions. This mode is entered if there are more than 127 devices in a loop and an AL_PA cannot be acquired. See also L_Port and Participating Mode. Not operational. A sequence that is transmitted by an FC_Port to indicate that the FC_Port has detected a link failure or is offline and is waiting for the offline sequence (OLS) to be received. A normal E_Port used to connect an MP Router to a backbone fabric. See Simple Name Server. Name Server Cache Manager. Software that updates the Name Server databases across switches as a background task. A node port that can operate as either an N_Port or NL_Port. Open fiber control. A method used to enable and disable laser signaling for higher-intensity laser transceivers. Fabric OS 5.x master glossary 21
