Glossary
disk pool A group of drives from which virtual drives are created. The drives that make
up the disk pool are called pool drives. A pool drive is multipathed disk drive
that corresponds to a Sun StorEdge T3+ array physical LUN.
Dynamic Multi-Pathing
(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 an N port. A Fibre Channel
port in 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. FC-AL is implemented as either a loop or a
Fabric. 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 allow the division of the Fabric (one or more switch chassis) into
as many as 16 Fabric-wide zones that define the ports that can communicate
with each other. A particular port may be placed in only one Hard Zone (no
overlapping Hard Zones). If Hard Zones are enabled, Name Server Zones and
SL Zones do not communicate across defined Hard Zone boundaries.
