Intel® Server Board S5500WB TPS Functional Architecture 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 preoperating 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.  Two internal 2x5 headers are provided, capable of supporting two optional USB 2.0 ports each, typically, one header supports Front panel USB and one supports an internal third party management card.  One internal low-profile 2x5 header is provided  One Internal Type A USB vertical connector is provided for attaching standard peripherals  The BMC consumes 2 ports, for a total of 12 Ports Revision 1.9 29 Intel order number E53971-008
