Glossary-1

The board that interfaces between the 
host system and the target devices. 
Adapter is synonymous with host bus 
adapter, host channel adapter (HCA), host 
adapter, and adapter board.

A port on the adapter board.

An LED on the adapter. Flashing it enables 
you to locate the adapter.

A user-defined name for an adapter, 
adapter port, logical disk, or subsystem.

The program (or utility) that serves as an 
interface between the hardware and the 
operating system and allows booting from 
the adapter at startup.

The device, usually a the hard disk, that 
contains the operating system the BIOS 
uses to boot from when the computer is 
started.

The ability for each server on a network to 
boot their operating system from a Fibre 
Channel RAID unit located on the SAN, 
rather than from a local disk or 
direct-attached storage (DAS). This 
enables easier SAN management 
because you can replace a server and 
boot it from the Fibre Channel RAID unit.

CHAP is used for remote logon, usually 
between a client and server or a Web 
browser and Web server. A 
challenge/response is a security mecha-
nism for verifying the identity of a person 
or process without revealing a secret 
password that is shared by the two 
entities. Also referred to as a” three-way 
handshake.” 

QLogic Converged Network Adapters 
support both data networking (TCP/IP) 
and storage networking (Fibre Channel) 
traffic on a single I/O adapter using two 
new technologies: Enhanced Ethernet and 
Fibre Channel over Ethernet.

A type of check value designed to catch 
most transmission errors.
