7.1.1
Staggered Disk Spin-Up
Because of the high density of disk drives that can be attached to the Intel® C620 onboard AHCI SATA
controller and the sSATA controller, the combined startup power demand surge for all drives at once can be
much higher than the normal running power requirements and could require a much larger power supply for
startup than for normal operations.
In order to mitigate this 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 up separately, with a certain delay between disk drives starting.
For the onboard SATA controller, staggered spin-up is an option –
AHCI HDD Staggered Spin-Up
– in the
Mass Storage Controller Configuration screen found in the BIOS setup utility.
7.2
Onboard SATA Software RAID Support
The server board includes support for two embedded SATA RAID options:
Intel® Rapid Storage Technology enterprise (Intel® RSTe) 5.0
Intel® Embedded Server RAID Technology 2 (ESRT2) 1.60
By default, onboard RAID options are disabled in BIOS setup. To enable onboard RAID support, access the
BIOS setup utility during POST. The onboard RAID options can be found under the
sSATA Controller
or
SATA Controller
options under the following BIOS setup menu:
Advanced -> Mass Storage Controller Configuration
Figure 62. BIOS setup Mass Storage Controller Configuration screen
Note
: 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.
