•
Boot support when using a RAID volume as a boot disk. It does this by providing Int13 services when
a RAID volume needs to be accessed by MS-DOS applications (such as NT loader (NTLDR)) and by ex-
porting the RAID volumes to the system BIOS for selection in the boot order.
•
At each boot-up, a status of the RAID volumes provided to the user.

Intel® Embedded Server RAID Technology 2 (Intel® ESRT2) 1.60 for SATA
Intel ESRT2 (powered by LSI*) is a driver-based RAID solution for SATA that is compatible with previous
generation Intel® server RAID solutions. Intel ESRT2 provides RAID levels 0, 1, and 10, with an optional
RAID 5 capability depending on whether a RAID upgrade key is installed.
Note: The embedded Intel ESRT2 option has no RAID support for PCIe NVMe SSDs.
Intel ESRT2 is based on LSI MegaRAID software stack and utilizes the system memory and CPU.
Supported RAID levels include.
•
RAID 0 – Uses striping to provide high data throughput, especially for large files in an environment
that does not require fault tolerance.
•
RAID 1 – Uses mirroring so that data written to one disk drive simultaneously writes to another disk
drive. This is good for small databases or other applications that require small capacity but complete
data redundancy
•
RAID 10 – A combination of RAID 0 and RAID 1, consists of striped data across mirrored spans. It pro-
vides high data throughput and complete data redundancy but uses a larger number of spans.
Optional support for RAID level 5 can be enabled with the addition of a RAID 5 upgrade key (iPN –
RKSATA4R5).
•
RAID 5 – Uses disk striping and parity data across all drives (distributed parity) to provide high data
throughput, especially for small random access.
