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 DMM appliance. 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. mSet See migration set. 20 Brocade Glossary Publication Number: 53-1000040-03
