BIOS - How to create RAID volume
Appendix
IND100077-250
Servers. If you are unsure we suggest to use default setting.
- Default is 16KB for RAID0 and 32KB for RAID5.
c. Set Capacity.
- Will be set to max available by default.
d. Set Synchronization (for Recovery option only).
- Continuous: Synchronize continuously when recovery volume is plugged in
- On Request: Synchronize only on request.
e. Select Create Volume to create the new RAID volume when everything is set.
- Warning: All existing data on selected drives will be lost!
f. Your RAID Volume is now ready for use.
- OS must be reinstalled or system image loaded.
- Note that Intel® RST RAID driver and software should be installed in OS for optimal RAID
performance and functionality
Create RAID Volume, Legacy mode
If boot mode is changed from UEFI (default and recommended for Win 10) to Legacy, the steps are slightly different.
Instead of entering main bios menu after enabling RAID, press Ctrl+i during boot to enter RAID BIOS menu (Intel RST
Option ROM).
After you have entered RAID BIOS, the steps to create RAID volume are the same as for step 3 in procedure for UEFI
above.
Available RAID levels:
- RAID 0 - Striping.
Requires 2+ drives.
Increased Read and Write performance.
No redundancy.
Not recommended for critical systems!
- RAID 1 - Mirroring.
Requires 2 drives.
Increased Read performance.
Good redundancy.
Recommended for most setups.
- RAID 5 - Block-level striping, with distributed parity.
Requires 3+ drives.
Increased Read and decreased Write performance.
Decent redundancy, only one drive can fail.
RAID5 is generally not recommended. It should be avoided for large drives (1TB+) due to slow rebuild time
and increased risk of second drive failure.
- RAID 10 - Mirrored and striped. Not available (requires 4 drives, only max 3 drives possible on HT B30 models).
- Recovery - Backup data to recovery disk.
Requires 2 drives.
This is not RAID but a backup function to copy data from master disk to a recovery disk.
Master and Recovery disk needs to be set in Select Disks option.
Available syncronisation options:
Continuous - Updated automatically.
On Request - Updated manually.
