Technical Product Specification

Intel® Server Board S5520UR and S5520URT TPS Functional Architecture
Revision 1.9 Intel order number E44031-012

3.4.2 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-0 through SATA-5. The SATA ports can be enabled or
disabled and/or configured by accessing the BIOS setup utility during POST.
3.4.2.1 Software RAID Support
The on-board 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. Should a disk fail, 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 I/O 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
3.4.2.2 Software RAID 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).
3.4.3 USB 2.0 Support
The USB controller functionality integrated into ICH10R provides the server board with an
interface for up to ten 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.
 One internal 2x5 header (J1J2) is provided, capable of supporting two optional USB
2.0 ports.
 Two ports are routed over the bridge board for chassis front panel USB ports and/or a
USB floppy drive. Due to the long route distance, those two ports are only capable of
supporting low-speed and full-speed modes.
