Glossary

HiPPI High Performance Parallel Interface, an 800-

or 1600-Mbit/second interface to

supercomputer networks (formerly known as

high-speed channel). Developed by ANSI.

Hunt Group A set of associated N_Ports attached to a

single node and assigned a special identifier

that allows any frames containing this

identifier to be routed to any available N_Port

within the set.

Hub A Fibre Channel device that connects nodes

into a logical loop by using an apparent star

topology. Hubs will automatically recognize

an active node and insert the node into the

loop. A node that fails or is powered off is

automatically removed from the loop.

Intermix A mode of service defined by Fibre Channel

that reserves the full Fibre Channel bandwidth

for a dedicated (Class 1) connection, but that

also allows connectionless traffic to share the

link if the bandwidth is available.

I/O Input/output

IP Internet Protocol

IPI Intelligent Peripheral Interface

L_Port A Fibre Channel port which supports the

arbitrated loop topology.

LAN See Local Area Network

Local Area Network (LAN) A communications system whose dimensions

typically are less than 5 kilometers.

Transmissions within a LAN are mostly

digital, carrying data among stations at rates

usually above one megabit/second.

receives and responds to login requests.

Multicast Refers to delivering a single transmission to

multiple destination N_Ports.

Name Server Provides translation from a given node name

to one or more associated N_Port identifiers

or their attributes.
