Intel® Server Board S5500WB TPS Functional Architecture
Revision 1.3
Intel order number E53971-004
29
• System Management Bus (SMBus) Specification, Version 2.0 with additional support
for I
2
C devices
• Low Pin Count (LPC) interface support
• Serial Peripheral Interface (SPI) support
3.7.1 Serial ATA Support
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-1 through SATA-6. You can enable or disable the SATA ports
and/or configure them by accessing the BIOS setup utility during POST.
3.7.1.1 Intel
®
Embedded Server RAID Technology II
The onboard storage capability of these server boards includes support for Intel
®
Embedded
Server RAID Technology II (Intel
®
ESRTII), which provides three standard software RAID levels:
data stripping (RAID Level 0), data mirroring (RAID Level 1), and data stripping with mirroring
(RAID Level 10). For higher performance, you can use data stripping to alleviate disk
bottlenecks by taking advantage of the dual independent DMA engines that each SATA port
offers. Data mirroring is used for data security. If a disk fails, a mirrored copy of the failed disk is
brought online. There is no loss of either PCI resources (request/grant pair) or add-in card slots.
With the addition of an optional Intel
®
RAID Activation Key, Intel
®
ESRTII is also capable of
providing fault tolerant data stripping (software RAID Level 5), such that if a SATA hard drive
fails, you can restore the lost data on a replacement drive from the other drives that make up
the RAID 5 pack.
Intel
®
Embedded Server RAID Technology functionality requires the following items:
• ICH10R IO Controller Hub
• Software RAID option is selected on BIOS menu for SATA controller
• Intel
®
Embedded Server RAID Technology II Option ROM
• Intel
®
Embedded Server RAID Technology II drivers, most recent revision
• At least two SATA hard disk drives
3.7.1.2 Intel
®
Embedded Server RAID Technology II Option ROM
The Intel
®
Embedded Server RAID Technology II for SATA Option ROM provides a pre-
operating system user interface for the Intel
®
Embedded Server RAID Technology II
implementation and provides the ability to use an Intel
®
Embedded Server RAID Technology II
volume as a boot disk as well as to detect any faults in the Intel
®
Embedded Server RAID
Technology II volume(s).
3.7.2 USB 2.0 Support
The USB controller functionality integrated into ICH10R provides the server board with an
interface for up to 12 USB 2.0 ports. All ports are high-speed, full-speed, and low-speed
capable.
• Four external connectors are located on the back edge of the server board.
