Dynamic Multipathing
(DMP) A VERITAS Volume Manager feature that provides an alternate pathing
mechanism for rerouting data in the event of a controller failover.
F port On a Fibre Channel switch, a port that supports a point-to-point or Fabric
connection.
Fabric A Fibre Channel network built around one or more switches. It is also common
to refer to something as a "Fabric device" or being in "Fabric mode." When
used in this context, it means a public device, capable of logging in to a Fabric
and having public loop characteristics (as opposed to a private loop legacy
device).
Fibre Channel A cost-effective gigabit communications link deployed across a wide range of
hardware.
FC-AL Fibre Channel-Arbitrated Loop. A loop can contain up to 126 nodes, accessible
through only one or two servers.
FRU field-replaceable unit. An assembly that a manufacturer replaces on failure of
an assembly component.
GBIC Gigabit interface converter. A hot-swappable input/output device that
connects in to a Gigabit Ethernet port or Fibre Channel.
Hard zones Hard zones enable the division of the Fabric (one or more switch chassis) into
multiple Fabric-wide zones that define the ports that can communicate with
each other.
HBA Host Bus Adapter. A controller board that connects the I/O expansion bus to
other Fibre Channel components.
hot spare A drive in a RAID 1 or RAID 5 configuration that contains no data and acts as
a standby in case another drive fails.
hot-swappable The ability of a field-replaceable unit (FRU) to be removed and replaced while
the system remains powered on and operational.
