BIOS - How to create RAID volume
Instructions
Before configuring it is assumed the user has the appropriate knowledge on how to enter and navigate within BIOS
and change values. When BIOS screen has been accessed, follow the steps below.
Enable RAID mode
1. Press Del key during boot (shortly after you hear the beep) to enter BIOS.
2. Go to “Chipset -> PCH-IO Configuration -> SATA and RST Configuration”
3. Set SATA mode selection to: “Intel RST Premium With Intel Optane System Acceleration”
4. Press F4 and and select Yes to save configuration.
5. Reboot is needed before RAID volume settings are enabled and available in BIOS.
Steps to set up RAID volume differs depending on if boot mode is set to UEFI (default) or Legacy.
Create RAID Volume, UEFI mode
1. After RAID has been set and unit rebooted, press Del key to enter BIOS.
2. Go to “Advanced -> Intel(R) Rapid Storage Technology”.
a. This menu will only show after RAID is enabled and system rebooted.
3. Select Create RAID Volume
a. Enter volume name. Default: Volume1
b. Select RAID Level. Available options depend on how many drives are connected.
- 2+ drives:
1. RAID0 (Stripe)
a. Increased Read and Write performance.
b. No redundancy.
c. Not recommended for critical systems!
2. RAID1 (Mirror)
a. Increased Read performance.
b. Good redundancy.
c. Recommended for most setups.
3. Recovery
a. This is not RAID but a backup function to copy data from master disk to a recovery
disk.
- 3+ drives:
1. RAID5 (Parity)
a. Increased Read and decreased Write performance.
b. Decent redundancy, only one drive can fail.
c. Not recommended for most setups. Should be avoided for large drives (1TB+) due
to rebuild time and increased risk of failure.
- 4 drives:
1. RAID10 ( Stripe)
a. Very good read and write performance.
b. Good redundancy, up to two drives can fail.
c. Best solution for setups where both increased performance and redundancy is
required.
c. Select disks to include in the new RAID volume
- Press Enter and select X option for each disk.
- If Recovery option is selected, M/R options will show instead.
1. M should be set for Master Disk
2. R should be set for Recovery Disk
b. Select Strip Size (RAID0 and RAID5 only).
- Low strip size is preferred for System drives and database. High strip size is preferred for File
