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.
