Functional Architecture Intel

Server Board S5000PAL/S5000XAL TPS

Revision 2.0

Intel order number: D31979-011

Note: Each PCI slot on the 2U PCI-X* (active) riser card operates on an independent PCI bus.

Therefore, using an add-in card that operates below 133MHz will not affect the bus speed of the

other PCI slots.

3.2.2 Serial ATA Support

The ESB-2 has an integrated Serial ATA (SATA) controller that supports independent DMA

operation on six ports and supports data transfer rates of up to 3.0 Gb/s.

The six SATA ports on

the server board are numbered SATA-0 thru SATA-5. The SATA ports can be enabled/disabled

and/or configured by accessing the BIOS Setup Utility during POST.

3.2.2.1 Intel

Embedded Server RAID Technology II Support

The onboard storage capability of this server board includes support for Intel

Embedded

Server RAID Technology 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, data stripping can be used 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 on-line.

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

Embedded Server RAID

Technology is also capable of providing fault tolerant data stripping (software RAID Level 5),

such that if a SATA hard drive should fail, the lost data can be restored on a replacement drive

from the other drives that make up the RAID 5 pack.

See Figure 2. Components & Connector Location Diagram for the location of Intel RAID

Activation Key connector location.

Note: Availability of the Intel RAID Activation Key to support software RAID 5 will be deferred

until after product launch of this server board.
