LSAN zone LUN LWL MALLOC MAN Mbps MBps meta-SAN metric MIA MIB MMF MOF MP MRK MS MSD The mechanism by which LSANs are administered. An MP 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. Logical unit number. The physical number of a device in a chain of drives connected in series. Long wavelength. A type of fiber optic cabling that is based on 1310-mm lasers and supports link speeds of 1.0625, 2.125, or 4.25 Gbps. Can also refer to the type of GBIC or SFP. See also SFP and SWL. Memory allocation. Usually relates to buffer credits. Metropolitan area network. A communications network that covers a geographic area, such as a city or a suburb. See also LAN and WAN. Megabits per second (1,048,576 bits/second). Megabytes per second (1, 048,576 bytes/second). 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. 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). A relative value assigned to a route to aid in calculating the shortest path (defaults to 1000 at 1 Gbps and 500 at 2 or 4 Gbps). Media interface adapter. A device that converts optical connections to copper ones, and vice-versa. Management Information Base. An SNMP structure to help with device management, providing configuration and device information. Multimode fiber. An optical fiber with a larger core than singlemode fiber. It is the most commonly used fiber for short distances, such as in LANs. See also LAN and SWL. Managed Object Format file. Management Platform. A platform running the HP Fibre Channel Routing Service or FC-to-FC routing (for instance, the HP StorageWorks Multi-protocol 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. Mark primitive signal. A signal that is used only in an arbitrated loop, is vendor-specific, and is transmitted by an L_Port for synchronization and is vendor specific. Management Server. A 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. Management Server daemon. A daemon that monitors the MS. Includes the Fabric Configuration Service and the Unzoned Name Server. 20 Glossary
