Server Board S5500BC TPS
Intel order number: E42249-003
Revision 1.0
32
The Intel
®
ICH10R provides six PCI Express* Root Ports which are compliant with the PCI
Express Base Specification, Revision 1.1. You can statically configure the PCI Express* root
ports 1-4 as four x 1 ports, or group them together to form two x2 ports, one x2 with two x1
ports, or one x4 port. You can only use ports 5 and 6 as two x1 ports or one x2. Port 6 is
multiplexed with a Gigabit LAN Connect Interface. The x4 configuration supports lane reversal.
Each root port supports 2.5 Gb/s bandwidth in each direction.
Ports 1-4 on the Intel
®
Server Board S5500BC are grouped together to form a single x4 link
connecting to an x4 PCI Express* Slot. Port 5 connects to the Integrated BMC for 2D video
function. Port 6 is used as Gigabit LAN Connect Interface and connected to the Ethernet device
PHY.
3.4.2
Serial ATA II Interface
The ICH10R has an integrated Serial ATA (SATA) controller that supports independent DMA
operation on six ports and data transfer rates of up to 3.0 Gb/s. The six SATA ports on the
server board are numbered SATA-0 through SATA-5. You can enable or disable the SATA ports
and/or configure them by accessing the BIOS setup utility during POST.
The BIOS Setup utility provides multiple drive configuration options on the Advanced | Mass
Storage Controller Configuration setup page, some of which affect the ability to configure RAID.
The “Onboard SATA Controller” option is enabled by default. When this option is enabled, you
can set the “SATA Mode” option to ENHANCED mode, COMPATIBILITY mode, AHCI mode, or
SW RAID mode. The modes affect the configuration as follows:
ENHANCED
mode
supports up to 6 SATA ports with IDE Native Mode.
COMPATIBILITY
mode
supports up to 4 SATA ports [0/1/2/3] with IDE Legacy mode and 2
SATA ports[4/5] with IDE Native Mode.
AHCI mode
supports all SATA ports using the Advanced Host Controller Interface when the
option is enabled. Note: For AHCI capability in EFI, you should set the AHCI legacy Option
ROM to “disabled”.
SW RAID mode
supports configuration of SATA ports for RAID via RAID configuration
software.
For RAID 0, 1, and 10, enclosure management is provided through the SATA_SGPIO connector
on the server board when a cable is attached between this connector on the server board and
to the backplane or I
2
C interface.
3.4.3
Software RAID Support
The Intel
®
Server Board provides six SATA ports (3 Gb/ps) using ICH10R with Intel
®
Embedded
Server RAID Technology, with SW RAID levels 0/1/10; with optional support for SW RAID 5 with
activation key.
If RAID 5 is needed, you can install the optional Intel
®
RAID Activation Key AXXRAKSW5. To
enable RAID 5, this activation key is placed on the SATA Key connector located on the right
side of the server board. For information on how to install the Intel
®
RAID Activation Key
