Glossary

Adapter

See HBA and CNA.

AL_PA

Arbitrated Loop_Physical Address. This is a low-level address on the FC loop.

Arbitrated loop

Anon-point-to-point circular topology that connects two or more ports, but only two ports can communicate at one time. The network passes all communication through all ports connected onto the loop.

BIOS

Basic Input/Output System. An HBA's flash PROM contains the code that allows booting from the HBA at startup.

Boot code

The first program to run when a system is powered on. This is also true for devices within a system, such as FC HBAs.

FCode, BIOS, and EFI (enhanced firmware interface) are all forms of boot code for specific hardware/operating system environments.

Boot code for QLogic FC adapters is required if the computer system is booting from a storage device (boot device) attached to the QLogic adapter.

The primary function of the boot code is communication with the external boot device before the operating system is up and running. The boot code can also perform secondary functions, including managing the setup for the adapter and initializing and testing the adapter’s ISP.

Boot device

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

CNA

Converged Network Adapter. CNAs support both data networking (TCP/IP) and storage networking (FC) traffic on a single I/O adapter using two new technolo- gies: Enhanced Ethernet and Fibre Channel over Ethernet (FCoE).

CRC

Cyclic Redundancy Check. A CRC is a type of check value designed to catch most transmission errors.

CSV file

Comma Separated Values file.

DCBX

Data Center Bridging Exchange. A networking protocol that allows switches and their target devices to automatically exchange Ethernet parameters.
