Intel® Embedded Server RAID Technology 2 (ESRT2) based on AVAGO* MegaRAID SW RAID technology 1.6
NOTE:
Using the BIOS Setup Utility, accessed during system POST, options are available to enable/disable SW RAID, and select which embedded software RAID option to use.
RAID partitions created using either RSTe or ESRT2 cannot span across the two embedded SATA controllers. Only drives attached to a common SATA controller can be included in a RAID partition.
