The SATA controller and the sSATA controller can be independently enabled to function in AHCI mode,
enabled to function in RAID mode or disabled. These controllers can be independently configured through
the BIOS Setup utility under the
Advanced > Mass Storage Controller Configuration
menu screen.

SATA Support Through Mini-SAS HD Connectors
The eight SATA ports on the server board are as follows:
•
Four ports from the Mini-SAS HD (SFF-
8643) connector labeled “SATA_0–3” on the server
board
•

8.1.3
Staggered Disk Spin-Up
A high density of hard drives can be attached to the Intel® C621A PCH chipset onboard AHCI SATA controller
and sSATA controller. The combined startup power demand surge for all attached hard drives at once can be
much higher than the normal running power requirements. This situation could require more power for
startup than for normal operations.
To mitigate this condition and lessen the peak power demand during system startup, both the AHCI SATA
Controller and the sSATA Controller implement a Staggered Spin-Up capability for the attached drives. This
means that the drives are started separately, with a certain delay between disk drives starting.
For the server board SATA controller, staggered spin-up is an option
