meta-SAN
The collection of all devices, switches, edge and backbone fabrics, LSANs, and FC routers that make up a
physically connected but logically partitioned storage network. LSANs span between edge fabrics using
FC routers. In a data network, this would simply be called the network. However, an additional term is
required to specify the difference between a single-fabric network (SAN), a multifabric network without
cross-fabric connectivity (dual-redundant fabric SAN), and a multifabric network with connectivity
(meta-SAN).
metric
A relative value assigned to a route to aid in calculating the shortest path (1000 at 1–Gbit/sec, 500 at
2–Gbit/sec).
MIB
Management Information Base. An SNMP structure to help with device management, providing
configuration and device information.
Name Server
Simple Name Server (SNS). 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. SNS is defined by Fibre Channel
standards and exists at a well-known address. Also called a directory service.
node
A Fibre Channel device that contains an N_Port or NL_Port. See also N_Port.
N_Port
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.
NS
Name Server. The service provided by a fabric switch that stores names, addresses, and attributes related
to Fibre Channel objects. Can cache information for up to 15 minutes. Also called a Simple Name Server
or a directory service.
Nx_Port
A node port that can operate as either an N_Port or NL_Port. See also N_Port.
originator
The Nx_Port that originated an exchange.
payload
A Fibre Channel frame has a header and a payload. The payload contains the information being
transported by the frame; it is determined by the higher-level service or FC_4 upper-level protocol. There
are many different payload formats, based on protocol.
PID
Port identifier. See also core PID.
point-to-point
A Fibre Channel topology that employs direct links between each pair of communicating entities. See also
topology.
port
In an HP StorageWorks switch environment, an SFP or GBIC receptacle on a switch to which an optical
cable for another device is attached.
