The RAID level migration feature in Intel® Rapid Storage Technology enterprise (Intel® RSTe) provides the ability to convert the contents of a drive into a RAID volume. The RAID level migration feature also supports the ability to migrate from one RAID volume to another.

 
Note Single volume per array only, which is dependent on required capacity and implicit array expansion.
 

RAID-Ready configuration migration 

Intel RSTe can support platforms based on Intel® C600 series chipset configured in RAID-Ready mode.

In a RAID-Ready configuration, you can take their single system drive and turn it into a supported RAID volume by using the Intel RSTe GUI application. This process does not require the reinstallation of the operating system. All applications and data remain intact.

 
Change Type from To
Individual pass-through 2 to 16 drive RAID 0
Individual pass-through 2 drive RAID 1
Individual pass-through 4 drive RAID 10
Individual pass-through 3 to 6 drive RAID 5
 

A RAID-Ready system refers to a system that is configured to support Intel RSTe. The system BIOS has the appropriate pre-boot drivers and is configured for RAID mode. RAID mode can be either:

  • The system is configured to boot off the AHCI controller and it is in RAID mode
  • The system is configured to boot off the SCU controller

RAID-to-RAID migration

Change Type from To
2 drive recovery volume 2 drive RAID 1
2 drive RAID 1 2 drive recovery volume
2 drive RAID 1 2 - 32 drive RAID 0

(where N can be 2 to 31)
N 1 – 32 drive RAID 5
(where N can be 2 to 31)
