Create Logical Disks Manually

• Logical Disk Specifications (below)

• Create a RAID 0 Logical Disk (page 27)

• Create a RAID 1 Logical Disk (page 29)

• Add Fault Tolerance to Existing Drive (page 30)

• Hot Spare Drive (page 33)

The FastBuild utility lets you create logical disks manually on your FastTrak

TX2200 or TX4200 Serial ATA RAID Controller card.

Logical Disk Specifications

There are several decisions you must make before you create a logical disk,

including:

• Logical Disk type

• Stripe Block Size

• Gigabyte Rounding

• Number of disk drives

• Use of new drives or drives with data

Logical Disk Type

The FastTrak offers three RAID level options:

• RAID 0 Stripe

• RAID 1 Mirror

• RAID 10 Mirror/Stripe

An alternative to creating a logical disk is to designate an unassigned drive as

JBOD. See page 23. JBOD drives act as single, independent disk drives. You

can have some of your disk drives in a logical disk and the rest in JBOD.

See page 45 for more information about RAID levels

Selecting Stripe Block

The available sizes are 32, 64 and128 KB. A larger block size is better when

handling large data transfers (such as in A/V editing or graphics) while a smaller

block size is better when handling e-mail and other common server data. The

default is 64 KB. When in doubt, use the default.

Gigabyte Rounding

When a logical disk goes Critical becamse a disk drive has failed, you must

replace the failed drive with one that is the same size or larger. However, the
