AcceleRAID 170 Installation Guide

Automatic Rebuild

Mylex controllers provide automatic rebuild capabilities in the event of a 
physical disk drive failure. The controller performs a rebuild operation 
automatically when a disk drive fails and both of the following conditions 
are true: 

A standby or hot spare disk drive of identical or larger size is found attached 
to the same controller; 

All system drives that are dependent on the failed disk drive are configured 
as a redundant array: RAID 1, RAID 3, RAID 5, or RAID 0+1. 

During the automatic rebuild process, system activity continues; however, 
system performance may degrade slightly.

BBU

Battery Backup Unit, provides a battery backup for data currently stored in 
the on-board cache memory during intermittent power loss to the controller. 
In the event of a power failure, the BBU can hold data in the cache for a 
certain amount of time. Once power is restored the data can be saved to a 
disk.

BIOS

Basic Input/Output System, software that determines what a computer can 
do without accessing programs. The BIOS contains all the code required to 
control the keyboard, screen, drives, serial communications, and other 
functions. Usually the BIOS is built into a ROM chip installed on the 
motherboard so that the BIOS will always be available and not affected by 
disk failure. Sometimes the BIOS is recorded on a flash memory chip.

BIOS Configuration Utility

BIOS-based Configuration Utility, a utility program sequence used, upon 
powerup, for configuring various hardware elements in a system.

Booting (or Bootstrapping)

Loading operating system code and other basic software from a disk or other 
storage device to help a computer start.

Burst Data Rate

The speed at which a specific amount of data is sent or received in 
intermittent operations.
