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.
