LSAN zone The mechanism by which LSANs are administered. An MP Router attached to two fabrics listen
for the creation of matching LSAN zones on both fabrics. If detected, it creates phantom
domains and FC-NAT entries as appropriate, and insert entries for them into the name servers
on the fabrics. LSAN zones are compatible with all standard zoning mechanisms.
Mbps Megabits per second.
metro-SAN The collection of all devices, switches, edge and backbone fabrics, LSANs, and MP Routers
that make up a physically connected but logically partitioned storage network. LSANs span
between edge fabrics using MP Routers. In a data network, this would simply be called the
network. An additional term is required, however, 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 Gbps,
500 at 2 Gbps).
MIB Management Information Base. An SNMP structure to help with device management,
providing configuration and device information.
MP Router Multi-protocol Router. A platform running the HP StorageWorks Fibre Channel Routing Service
or FC-to-FC routing. Enables two or more fabrics to share resources (such hosts or storage
devices) without merging those fabrics. The platform could simultaneously be used as an MP
Router and as an FCIP tunnel or iSCSI gateway.
MSRS Multiprotocol SAN Routing Services. An optionally licensed software bundle available on
certain HP StorageWorks platforms, such as the MP Router, that includes the Fibre Channel
Routing Service, the iSCSI Gateway Service, and the FCIP Tunneling Service.
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. See also NL_Port , Nx_Port .
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 directory service.
NAS Network-attached storage. A disk array connected to a controller that gives access via a LAN.
NL_Port 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 .
node A Fibre Channel device that contains an N_Port or NL_Port.
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
known as a Simple Name Server or directory service. See also simple name server (SNS) .
Nx_Port A node port that can operate as either an N_Port or NL_Port.
originator The Nx_Port that originated an exchange.
OX_ID Originator ID or exchange ID. The exchange ID assigned by the originator port.
parallel The simultaneous transmission of data bits over multiple lines.
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.
persistent error log Error messages of a high enough level (by default, Panic or Critical) are saved to flash memory
on the switch instead of to RAM. These messages are saved over reboots and power cycles,
constituting the persistent error log. Note that each CP on an HP StorageWorks Core Switch
2/64 has its own unique persistent error log.
