LRR Link reset response. A primitive sequence during link initialization between two N_Ports in
point-to-point topology or an N_Port and an F_Port in fabric topology. It is sent in response to
an LR and expects a response of Idle.
LSAN Logical storage area network. An LSAN enables device and storage connectivity that spans
two or more fabrics. The path between devices in an LSAN can be local to a fabric or cross
one or more FC routers and one or more backbone fabrics.
LSAN zone The mechanism by which LSANs are administered. An FC router attached to two fabrics will
"listen" for the creation of matching LSAN zones on both fabrics. If this occurs, it will create
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.
LWL Long wavelength. A type of fiber optic cabling that is based on 1300-mm lasers and supports
link speeds of 1.0625 Gb/sec. Can also see the type of GBIC or SFP. See also SWL.
MALLOC Memory allocation. Usually relates to buffer credits.
MAN Metropolitan area network.
MB/s Megabytes per second.
Mb/s Megabits per second.
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 @ 1 Gb/s,
500 @ 2 Gb/s).
MIA Media interface adapter. A device that converts optical connections to copper ones, and
vice-versa.
MIB Management Information Base. An SNMP structure to help with device management,
providing configuration and device information.
MMF Multimode fiber. See SWL.
MOF Managed Object Format file.
MP router A platform running the HP Fibre Channel Routing Service or FC-to-FC routing (for instance, the
StorageWorks MP Router) that 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.
MRK Mark primitive signal. Used only in arbitrated loop, MRK is transmitted by an L_Port for
synchronization and is vendor specific.
MS Management Server. The Management Server allows a storage area network (SAN)
management application to retrieve information and administer the fabric and interconnected
elements, such as switches, servers, and storage devices. The MS is located at the Fibre
Channel well-known address FFFFFAh.
MSD Management Server daemon. Monitors the MS. Includes the Fabric Configuration Service and
the Unzoned Name Server.
