Intel Corporation server baseboards contain a number of high-density VLSI and power delivery
components that need adequate airflow to cool. Intel’s own chassis are designed and tested to
meet the intended thermal requirements of these components when the fully integrated system
is used together. It is the responsibility of the system integrator that chooses not to use Intel
developed server building blocks to consult vendor datasheets and operating parameters to
determine the amount of air flow required for their specific application and environmental
conditions. Intel Corporation cannot be held responsible if components fail or the server board
does not operate correctly when used outside any of their published operating or non-operating
limits.

2.4 Intel® 82571EB Gb Ethernet Controller
The Intel® 82571EB Gb Ethernet Controller is a single, compact component with two fully
integrated Gb Ethernet Media Access Control (MAC) and physical layer (PHY) ports. This
device uses the PCI Express* architecture (Rev. 1.0a) and also enables a dual-port Gb Ethernet
implementation. The Intel® 82571EB Gb Ethernet Controller provides two IEEE 802.3 Ethernet
interfaces for 1000BASE-T, 100BASE-TX, and 10BASE-T applications. Both ports also
integrate a Serializer-Deserializer (SerDes) to support 1000BASE-SX or 1000BASE-LX (optical
fiber) and Gb backplane applications. In addition to managing MAC and PHY Ethernet layer
functions, the controller manages PCI Express* packet traffic across its transaction, link, and
physical/logical layers.
The Intel® 82571EB Gb Ethernet Controller for PCI Express* is designed for high-performance
and low memory latency. The device is optimized to connect to a system Memory Control Hub
(MCH) using up to four PCI Express* lanes. Wide internal data paths eliminate performance
bottlenecks by efficiently handling large address and data words. Combining parallel and
pipelined logic architecture optimized for Gb Ethernet and for independent transmit and receive
queues, the controller efficiently handles packets with minimum latency. The controller includes
advanced interrupt-handling features and uses efficient ring-buffer descriptor data structures
with up to 64 packet descriptors cached on chip. A large 48 Kbyte per port on-chip packet buffer
maintains superior performance. Using hardware acceleration, the controller offloads tasks from

3.4 LSI* SAS1064E 3.0 Gbit/s Serial Attached SCSI Controller
Integrated on the SAS I/O module is an LSI* SAS1064E Serial Attached SCSI (SAS) controller.
The LSISAS1064E is a four-port, 3.0 Gbit/s SAS/SATA controller compliant with the Fusion-
MPT* architecture, and provides a four-lane PCI Express* interface. The point-to-point
interconnect feature of the PCI Express* bus limits the electrical load on links, allowing
increased transmission and reception frequencies. PCI Express* transmission and reception
data rates for each full-duplex interconnect is 2.5 Gbit/s.

Figure 9. LSI* SAS1064E Block Diagram
PCI Express* implements a switch-based technology to interconnect a large number of devices.
Communication over the serial interconnect is accomplished using packet-based
communication protocol. Quality of Service (QOS) features provide differentiated transmission
performance for different applications. Hot plug/hot swap support enables “always-on” systems.
Enhanced error handling features, such as end-to-end CRC (ECRC) and Advanced Error
Reporting, make PCI Express suitable for robust, high-end server applications. Hot plug, power
management, error handling, and interrupt signaling are accomplished using packet-based
messaging rather than sideband signals.
Each of the four SAS PHYs on the LSISAS1064E is capable of SAS/SATA link rates of 3.0
Gbit/s and 1.5 Gbit/s. The user can configure ports as wide or narrow. Narrow ports have one
PHY per port. Wide ports have two, three, or four PHYs per port. Each port supports the SSP,
SMP, STP, and SATA protocols.
The SAS interface uses the proven SCSI command set to ensure reliable data transfers, while
providing the connectivity and flexibility of point-to-point serial data transfers. The SAS interface
provides improved performance, simplified cabling, smaller connectors, lower pin count, and
lower power requirements when compared to parallel SCSI. SAS controllers leverage an
electrical and physical connection interface that is compatible with Serial ATA technology.
The LSISAS1064E uses the Fusion-MPT* (Message Passing Technology) architecture, which
features a performance-based message passing protocol that offloads the host CPU by
completely managing all I/Os and minimizes system bus overhead by coalescing interrupts. The
proven Fusion-MPT* architecture requires only thin, easy-to-develop device drivers independent
of the I/O bus. LSI* Logic provides these device drivers.

7.4 Intel® 82576 1 Gb Ethernet Controller
The Intel® 82576 1 Gb Ethernet Controller is a single, compact component with two fully
integrated 1 Gb Ethernet Media Access Control (MAC).
The Intel® 82576 supports X4 PCI-Express Gen2 connection, and support I/OAT V3.0
(Input/Output Acceleration Technology). These give the device a high-performance and low-
host memory access latency feature. In addition, the wide internal data path eliminates
performance bottlenecks by efficiently handling large address and data words. To further
optimize the latency from system level, the PCI-Express* x8 interface is directly connected to
IOH.

The Quad Port Gb Ethernet I/O module provides a SPI serial EEPROM to store configuration
and informational data. This includes pre-boot configuration data, MAC address, and serial

8.4 Intel® 82598 10 Gb Ethernet Controller
The Intel® 82598EB 10 Gb Ethernet Controller is a single, compact component with two fully
integrated 10 Gb Ethernet Media Access Control (MAC) and XAUI ports.
The Intel® 82598EB is a follow-on design to the prior generations of Intel® 1Gbit, 10 Gbit
Ethernet controllers. It provides new features and retains many of its predecessors’ features.
The Intel® 82598EB supports X8 PCI-Express Gen2 connection and I/OAT V2.0 (Input/Output
Acceleration Technology). These give the device a high-performance and low-host memory
access latency feature. In addition, the wide internal data path eliminates performance
bottlenecks by efficiently handling large address and data words. The parallel and pipelined
logic combined architecture is optimized for Ethernet and independent transmit and receive
queues, this means the 82598EB can process the packet with minimum latency. To further
optimize the latency from system level, the PCI-Express* x8 interface is connected to IOH
directly.

8.7 CX4 Ethernet Connector
The Dual Gb Ethernet I/O module contains two CX4 10 Gbit Ethernet connectors compatible
with 10 Gbit Ethernet CX4 connections. The CX4 port embeds the feature which can support
active cable (copper-fiber optic – copper), so it enlarges the distance of the 10 Gbit Ethernet
connections from 10 m up to 100 m.

12. Integrated RAID Module RMS2LL040 &
RMS2LL080
The Intel® RAID Module RMS2LL040 and RMS2LL080 are intelligent custom board-to-board
PCI Express* 2.0 compliant interface RAID adapters with an integrated LSI* LSISAS2008
Processor Chip, providing both a SAS controller and RAID engine. With four (RMS2LL040) or
eight (RMS2LL080) independent ports supporting 6-Gbps and 3 Gbps SAS data transfers using
four or eight individual SAS/SATA connectors, this controller supports up to 32 enterprise-class
SAS or SATA devices and 64 logical drives. The PCI Express* connector fits into a 50 pin
connector capable of performance up to 5 Gbps per lane. Includes support for RAID levels 0, 1,
and 1E. For more details see the Intel® Integrated RAID Module RMS2LL040 (AXXRMS2LL040)
and RMS2LL080 (AXXRMS2LL080) Hardware User’s Guide.
