Dual Intel® Xeon ™ processor
at 2.4GHz. Processor Package: FC-mPGA2 package (604-pin)
The Xeon processors support a 533MHz system bus as well as
Intel’s NetBurst™ Micro-architecture. Both features
combine to provide robust performance and fast program execution.
Some of the processor features that enable such performance
enhancements are:
|
| |
• Hyper-Pipelined technology
|
| |
• Streaming SIMD Extensions 2 (SSE2)
|
| |
• Advanced Dynamic Execution
|
| |
• 512K Advanced Transfer Cache (L2)
|
| |
• 12K trace and data cache (L1) Intel’s
Hyper-Threading technology makes a single Xeon processor
appear as two logical processors. The XPT’s two physical
processors will function as four logical processors in applications
optimized for Hyper-Threading.
|
| E750I Chipset |
The chipset supports a 400/533MHz system bus,
DDR200/266 memory with ECC and a high-speed Hub Link 2.0
interface.
|
| Dual 10/100/1000 Ethernet Interfaces |
The OSS-SBC-2X has an internal PCI-X bus that
connects to Intel's 82546EB Ethernet Controller chip. This
board design feature provides high-speed dual Gigabit Ethernet
on LAN ports 1 and 2. The OSS-SBC-2X also supports existing
10Mb/s or 100Mb/s Ethernet networks over the same internal
PCI-X bus. RJ-45 connectors located on the I/O bracket provide
the mechanical interface to the Ethernet networks.
|
| DUAL Ultra 320 SCSI Interfaces |
The Ultra320 SCSI interfaces use a dual-channel
Adaptec AIC-7902 SCSI controller chip. The SCSI interfaces
use the SBC’s internal PCI-X bus to maximize device
data transfer speeds. The maximum data transfer speed is
320MB/s and up to 15 SCSI devices per interface are supported.
The interfaces comply with the SPI-3 standard and are compatible
with both single-ended and Low Voltage Differential (LVD)
SCSI I/O. Software drivers are available for most popular
operating systems. The SBC is available without the SCSI
interfaces.
|
| DDR200/266 Memory |
The DDR memory interface on the OSS-SBC-2X
consists of two channels, each terminating at a pair of DIMM
module sockets. The OSS-SBC-2X supports auto detection of
up to 8GB of memory. The system BIOS automatically detects
memory type, size and speed. The four memory sockets on the
SBC must be populated in pairs, beginning with the sockets
in Bank 1, and must contain ECC registered PC1600 or PC2100
DIMMS. All DIMMS must be the same speed (PC1600 or PC2100).
The modules within a pair must be the same size; however,
if two pairs are used, each pair can contain a different
size module. The maximum memory capacity of the OSS-SBC-2X
is 8GB and the minimum interface bandwidth is 1600MB/s.
|
| EIDE Ultra ATA/100 Interfaces (Dual) |
Dual high-performance PCI EIDE interfaces
are capable of supporting up to two IDE disk drives each
in a master/slave configuration. The interfaces support Ultra
ATA/100 with synchronous ATA mode transfers up to 100MB per
second.

|
| BIOS (Flash) |
The XPT uses the AMIBIOS8®. The flash
BIOS resides in the 82802 Firmware Hub (FWH). AMIBIOS8 contains
important features such as:
|
| |
• Boot from USB mass storage devices,
SCSI, IDE or ATAPI
|
| |
• Boot from network LAN (optional)
|
| |
• Serial port console redirection to
support headless operation
|
| |
• PCI bus support includes 64-bit & PCI-X
capability
|
| |
•ATA/ATAPI support includes 48-bit LBA
addressing to support ATA/IDE hard drive capacities over
137GB
|
| |
• Integrated support for USB mass storage
devices such as USB CD-ROM, CD-RW, etc.
|
| |
• Fast POST support
|
| Ultra XGA Interface |
The ATI M6-16H video controller enables 2D/3D
video acceleration and provides 16MB of integrated video
DDR memory. The video controller supports pixel resolutions
up to 1600 x 1200. Software drivers are available for most
popular operating systems.

The Xeon processor’s power requirements
created the need for an additional on-board 4-pin connector
(P24). This connector requires +12V from an external power
supply that conforms to the ATX12V power specification. This
external power supply should have a minimum attage rating
of a least 250W. The XPT also requires that +3.3V be applied
to the backplane from the power supply. Temperature/Environment:|Operating

A Xeon processor can consume as much as 70
watts each of power on the OSS-SBC-2X. The OSS-SBC-2X's cooling
system consists of an air duct assembly attached to the SBC,
a high-realibity cooling fan mounted to the air duct intake,
and passive heat sinks mounted to each processor. The fan
maintains air movement over the processors’ passive
heat sinks and the air duct assembly directs the airflow
over critical components.
|
| |
Warm air is exhausted from vents located on
the SBC’s I/O bracket. Mechanical:|In a typical PCI/ISA
backplane, the XPT's air duct design enables placement of
half-size PCI cards approximately 2.3" (58.4mm) or three
slots away from the SBC. Full-length cards can be placed
four slots away in the backplane or approximately 3.2" (81.3mm)
from the OSS-SBC-2X.
