Glossary
LWL
Long wavelength. A type of fiber optic cabling that is based on 1310-mm lasers and supports link
speeds of 1.0625, 2.125, and/or 4.25 Gbit/sec. Can also refer to the type of GBIC or SFP. See also SWL.
M
MALLOC
Memory allocation. Usually relates to buffer credits.
MAN Metropolitan area network.
Mbit/sec
Megabits per second.
MB/sec Megabytes per second.
metaSAN
The collection of all SAN devices, switches, edge fabrics, LSANs, and multiprotocol routers that make
up a physically connected but logically partitioned storage area network.
metric
A relative value assigned to a route to aid in calculating the shortest path (defaults to 1000 at 1 Gbit/sec,
500 at 2 or 4 Gbit/sec).
MIA Media interface adapter. A device that converts optical connections to copper ones and vice versa.
MIB
Management Information Base. A tree structure of configuration data on a switch. MIBs can be used to
manage the configuration of a switch from an SNMP management station. Every Brocade switch carries
an SNMP agent (for communicating with an SNMP management station) and a MIB. See also SNMP.
migration set
(mSet) In DMM, a collection of ePairs that comprise a migration. DMM uses migration sets to
configure migrations and scheduling policies. See also
MMF Multimode fiber. See also SWL.
MOF
Managed Object Format file.
morphed WWN In a Brocade SAN, ADs are treated as fabrics. Since switches cannot be part of two fabrics but they can
be part of two ADs, their WWNs are "morphed" so that they appear as unique entities in different
fabrics.
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.
