HP P4459A 8-Port Fibre Loop Switch Installation & Opeartion Guide

Full Duplex Communications

A pair of nodes able to both simultaneously send and receive data between each other for an aggregate of 2 Gbps, effectively doubling the communications rate between the two nodes.

Frame

The smallest unit of information carrying user data and protected by Fibre Channel error control and recovery. Up to 2112 bytes per frame can be transported.

GBIC

Gigabit Interface Converter. It is a connector that offers flexible choice of media and transmission technology.

Gigabit

One billion bits or one thousand megabits. It is generally used to refer to bandwidth.

HBA

Host Bus Adapter is a card that connects FC peripherals and server host buses such as PCI and others. It also requires a device driver.

Hub

A central connecting device in a network that joins communication lines into a star configuration.

In band

“In bandwidth.” Using the same bandwidth (wires or data channel) for signaling as for data transmission.

IP

Internet Protocol. A protocol designed for use in interconnected systems of packet networks.

Jitter

Unwanted variations in the frequency or phase of a digital or analog signal due to varying time delays in the circuit paths from component to component in the signal path. Jitter can cause errors and data corruption.

LAN

Local Area Network. A communications system whose geography covers less than 5 kilometers. Transmissions within it are mostly digital, carrying data among stations at rates usually above 1 Mbit/sec.

Latency

The time delay of data traffic through a network or a switch.
