Brocade SAN Glossary
Logical Storage Area Network. Enables device and storage connectivity that
spans two or more fabrics.
The total number of port WWN entries for all devices defined in all active
LSAN zones within a routed fabric.
The mechanism by which LSANs are administered. A Multiprotocol 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 standard zoning mechanisms.
The number of port WWN entries defined in an edge fabric or backbone
LSAN zone.
Logical Unit. A piece of logical storage in a disk array.
In Brocade Data Migration Manager, identifies a path to a logical unit; the
port WWN (pWWN) of the array and the LUN from the standpoint of the
virtual initiators.
Logical Unit Number. The path to an LU or the 64-bit address of the LU.
Mapping between a virtual iSCSI target and physical FC target.
Long Wavelength fiber-optic; based on 1300 and 1550-nm lasers supporting
1, 2, and 4 Gbit/sec link speeds.
Media Access Control address. The address used for communication
between network adapters on the same subnet. Each network adapter has
an associated MAC address.
Memory allocation; usually refers to buffer credits.
Metropolitan Area Network.
Megabits per second; also "Mbit/sec."
Megabytes per second; also "MB/sec."
The collection of all devices, switches, edge and backbone fabrics, LSANs,
and Multiprotocol Routers that make up a physically connected but logically
partitioned storage network. 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 multi-fabric network
without cross-fabric connectivity (for example, a dual-redundant fabric SAN),
and a multi-fabric network with connectivity (metaSAN).
A relative value assigned to a route to aid in calculating the shortest path
(1000 @ 1Gbit/sec, 500 @ 2Gbit/sec).
Media Interface Adapter. A device that converts optical connections to
copper ones and vice versa.
Management Information Base. An SNMP structure for device management
that contains an abstraction of configuration and device information.
