port A The relative number of an HBA. A specific port number is determined according
to its order of discovery by the Windows operating system. HBA's include SCSI,
Fibre Channel, and IDE adapter types.
SAN Storage Area Network. A configuration of networked devices for storage.
target The definition of target depends on the environment:
• For parallel SCSI configurations, the target is the actual target number as-
signed to a device.
• For Fibre Channel configurations, a target number is assigned by a mapping
function at the miniport-driver level and is derived from AL_PA (Arbitrated
Loop Physical Addresses) in an FC-AL topology.
• For SAN switched fabric, a target is assigned to a WWPN. This target can
have values between 16 and 125.
• For a fabric topology, target is a mapping function derived from the order
of discovery according to port connections at the SAN (Storage Area Network)
switch.
topology An interconnection scheme that allows multiple servers and storage devices to
communicate. Arbitrated loop and switched fabric are examples of Fibre Channel
topologies.
