ACS-61100 User’s Manual
BIOS Menu
The menu below gives brief information about the functions of the BIOS menu. For further
details see the RAIDGuard X user manual.
A. RAID Config
Create Array Quickly create and array, administer the details of a current and array
and configure a JBOD. A collection of disks from one or more
commonly accessible disk controllers, combined with a body of Array
Management Software. Array Management Software controls the disks
and presents them to the array operating environment as one or more
virtual disks.
Set Slice Add and delete slices. Unlike striping, slicing allows the creation of
arrays from a single disk without a loss of speed as the disk fills up.
This is because when striping across disks the center of the disk fills
up and when it’s being written to it slows down. Slicing creates new
disk partitions with similar characteristics, therefore keeping the speed
the same.
LUN and Map Display details and sets LUNs and Maps. A LUN (Logical Unit
Number) is a unique identifier used on a SCSI bus that enables it to
differentiate between up to eight separate devices (or logical unit).
Each LUN is a unique number that identifies a specific logical unit,
which may be an end user, a file, or an application.
Locked Disk Unlock locked disks. Disks that’ have been locked because of an error
can be unlocked.
B. Disk Config Utility
Automatic
Detection Detects installed disks. Before a new disk can be added to an array it
first needs to be detected.
Disk Information Displays manufacturer and speed details of the installed disks.
