Storage Controller Options Overview
The server platform supports many different embedded and add-in SATA/SAS controller and
SAS Expander options to provide a large number of possible storage configurations. This
chapter provides an overview of the different options available.
6.1
Embedded SATA/SAS Controller Support
Integrated on the server board is an Intel
®
C600-A chipset that provides embedded storage
support via two integrated controllers: AHCI and SCU.
The standard server board (with no additional storage options installed) supports up to six SATA
ports:
Two single 6 Gb/sec SATA ports routed from the AHCI controller to two white 7-pin
SATA ports labeled
SATA-0
and
SATA-1
on the server board. Embedded RAID levels 0
and 1 supported.
Four 3 Gb/sec SATA ports routed from the SCU controller to the multi-port mini-SAS
connector labeled
SCU_0 (0-3)
.
Note: The mini-SAS connector labeled “SCU_1 (4-7)” is NOT functional by default and is only
enabled with the addition of an Intel
®
RAID C600 Upgrade Key option supporting 8 SAS/SATA
ports.
With the addition of one of several available Intel
®
RAID C600 Upgrade Keys, the system is
capable of supporting additional embedded SATA, SAS, and software RAID options. Upgrade
keys install onto a 4-pin connector on the server board labeled
STOR_UPG_KEY
.
