Glossary network-attached storage network management nickname NL_Port node node loop port node port node port identifier nonvolatile random access memory N_Port N_Port ID NV-RAM NAS. Storage connected directly to the network, through a processor and its own operating system. Lacks the processor power to run centralized, shared applications. The broad subject of managing computer networks. There exists a wide variety of software and hardware products that help network system administrators manage a network. Network management covers a wide area, including security, performance, and reliability. Alternate name assigned to a world-wide name for a node, director or switch in the fabric. See node loop port. In Fibre Channel protocol, an end device (server or storage device) that is or can be connected to a switched fabric. See also device. NL_Port. A physical interface within an end device (node) that participates in a loop containing one or more fabric loop ports (FL_Ports) or other NL_Ports. See also expansion port; fabric loop port; fabric port; generic port; hub port; node port; segmented expansion port. N_Port. Physical interface within an end device that can connect to an fabric port (F_Port) on a switched fabric or directly to another N_Port (in point-to-point communications). See also expansion port; fabric loop port; fabric port; generic port; hub port; node loop port; segmented expansion port. N_Port ID. In Fibre Channel protocol, a unique address identifier by which an N_Port is uniquely known. It consists of a domain (most significant byte), an area, and a port, each 1 byte long. The N_Port ID is used in the source identifier (S_ID) and destination identifier (D_ID) fields of a Fibre Channel frame. NV-RAM. RAM that retains its content when the device power is turned off. See node port. See node port identifier. See nonvolatile random access memory. g-29
