2.1 RAID configurations

If your motherboard supports RaidXpert2 Configuration Utility, you can create Volume,

RAIDABLE, RAID 0, RAID 1, or RAID 10 (depends on system licensing) configurations.

If you want to install a Windows

operating system to a hard disk drive included in a RAID

set, you have to create a RAID driver disk and load the RAID driver during OS installation.

Refer to section 2.2 Installing the RAID controller driver during Windows

10 OS

installation for details.

2.1.1 RAID definitions

Volume provides the ability to link-together storage from one or several disks, regardless

of the size of the space on those disks. This configuration is useful in scavenging space on

disks unused by other disks in the array. This configuration does not provide performance

benefits or data redundancy, disk failure will result in data loss.

RAIDABLE arrays (also known as RAID Ready) are a special type of Volume (JBOD) that

allows the user to add more storage space or create a redundant array after a system is

installed. RAIDABLE arrays are created using Option ROM, UEFI, or rcadm.

The ability to create RAIDABLE arrays may vary per system.

RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in

parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a

sustained data transfer rate, double that of a single disk alone, thus improving data access

and storage. Use of two new identical hard disk drives is required for this setup.

RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to

a second drive. If one drive fails, the disk array management software directs all applications

to the surviving drive as it contains a complete copy of the data in the other drive. This RAID

configuration provides data protection and increases fault tolerance to the entire system.

Use two new drives or use an existing drive and a new drive for this setup. The new drive

must be of the same size or larger than the existing drive.

RAID 10 is data striping and data mirroring combined without parity (redundancy data)

having to be calculated and written. With the RAID 10 configuration you get all the benefits

of both RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing

drive and three new drives for this setup.
