HP P4459A 8-Port Fibre Loop Switch Installation & Opeartion Guide
Out-of-band
Using a separate channel for signaling to ensure full bandwidth availability for its
primary purpose. For example, although more costly, it ensures full bandwidth
availability for voice or critical data transmission.
PLDA
Private Loop Direct Attach. A profile that defines an interoperable FC-AL
implementation.
Port
A hardware pathway into and out of a node that performs data communications over
the FC link. For example, a "dual-ported" device has two separated pathways by
which data is transferred.
Private Loop
A Fibre Channel Arbitrated Loop that stands on its own and is not connected to a
fabric.
Protocol
A set of conventions or rules used by a program or operating system to
communicate between two or more endpoints. Examples include IPX, TCP/IP, and
AppleTalk. Though the protocols differ, they all allow information to be packaged,
sent from a source, and delivered to a destination system.
Public Loop
A Fibre Channel Arbitrated Loop that is connected to a fabric.
RAID
Redundant Array of Inexpensive Disks. It is a disk subsystem that appears as a
single, large, fast disk drive, even though it is in reality composed of an array of
drives.
RFI
Radio Frequency Interference.
Ring
A configuration of computing devices interconnected in a ring shape. The
communication between any two points always includes all of the intermediate
points.
