Chapter 6. RAID

What is RAID

Redundant Array of Independent Disks (RAID) is a technology that provides increased storage functions and reliability through redundancy. It also can improve data storage reliability and fault tolerance compared with single-drive storage systems. Data loss resulting from a drive failure can be prevented by reconstructing missing data from the remaining drives.

When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID array. This array distributes data across multiple storage drives, but the array appears to the host computer as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited I/O performance, because several drives can be accessed simultaneously.

Select RAID mode

You can select the SATA RAID mode or NVMe RAID mode to configure RAID with RAIDXpert2 Configuration Utility.

1. Do one of the following to select the SATA RAID mode or NVMe RAID mode:

• SATA RAID mode: a. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1. b. Select Devices ➙ ATA Drive Setup ➙ Configure SATA as (AHCI/RAID). c. Select RAID.

• NVMe RAID mode: a. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1. b. Select Devices ➙ NVMe Setup ➙ NVMe RAID Mode (Enabled/Disabled). c. Select Enabled.

2. Press F10 or Fn+F10 to save the changes and exit.

3. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.

4. Select Devices ➙ RAIDXpert2 Configuration Utility to select drives and configure RAID.

RAID Levels

CAUTION:

• Only one redundant RAID array is supported by AMD-RAID. RAID1, RAID5, and RAID10 are all redundant arrays.

• The AMD-RAID does not support more than eight arrays, including Non-RAID array.

• Multiple operating systems are not supported on AMD-RAID Array. If the system is booted from an AMD-RAID bootable array, the first array in the Arrays section must be the bootable array. The system boots only from the first array in the Arrays section. Refer to “Configure RAID with RAIDXpert2 Configuration Utility” on page 34 to find the first array by viewing array details and checking the array number.

Your computer supports the following RAID levels:

• RAID 0: striped disk array

– Provide the highest performance but no data redundancy. Data in the array is striped (distributed)

across several disks. – Support 2-8 disks. – RAID 0 arrays are useful for holding information, such as the operating system paging file, where

performance is extremely important but redundancy is not.

• RAID 1: mirrored disk array

– Mirror data on a partition of one disk to another. – Support 2 disks. – RAID 1 arrays are useful when there are only two disks available and data integrity is more important

than storage capacity.

• RAID 5: block-level striped disk array with distributed parity

– Stripe data as well as parity, across all disks in the array. – Support 3-8 disks. – Offer exceptional read performance and redundancy.

• RAID 10: striped and mirrored disk array (a combination of RAID 0 and RAID 1)

– Combine mirrors and stripe sets. RAID 10 allows multiple disk failures, up to 1 failure in each mirror that

has been striped. – Support 4, 6, or 8 disks. – Offer better performance than a simple mirror because of the extra disks. Require twice the disk space

of RAID 1 to offer redundancy.

• Volume (JBOD):

– RAIDXpert2 Configuration Utility treats one or more disks or the unused space on a disk as a single

array. – Support 1-8 disks. – Provide the ability to link-together storage from one or several disks, regardless of the size of the space

on those disks. It is useful in scavenging space on disks unused by other disks in the array. It does not

provide performance benefits or data redundancy. Disk failure will result in data loss.

• RAIDABLE (also known as RAID Ready):

– Allow a RAIDABLE disk to be transformed later to RAID 0 or RAID 1. – Support 1 disk.

Configure RAID with RAIDXpert2 Configuration Utility

If your computer comes with the RAIDXpert2 Configuration Utility , you can follow the sections below to configure RAID.

Initialize disks

New disks and legacy disks must be initialized before they can be used to create an AMD-RAID array. Initialization writes AMD-RAID configuration information (metadata) to a disk.

CAUTION:

• If a disk is part of an AMD-RAID array, the disk cannot be selected for initialization. To initialize the disk anyway, delete the AMD-RAID array. Data on the disk is deleted during initialization so ensure the correct disks are chosen to initialize.

• A legacy disk can contain valid data. When a legacy array is deleted, all data on the disk is lost.
