Chapter 1
1. Chassis Description
The SGI 1100 server is a 1U, high-density, rackmountable, PCI bus-based dual-processor
system built on an extended ATX baseboard. It comes with two socket 370 processor
sockets utilizing one or two Intel Pentium III processors integrated with the Server
Works LE north and OSB4 south bridge chipsets. The system board integrates two Intel
82559 10/100 Mbps PCI E the rn et chi ps et s that s u pports WOL (w ak e on LA N) fo r bett er
remote site management.
For expandability , the system includes one 64-bit/66-MHz PCI bus slot and four DIMM
slots that allow memory installation to a maximum of 2 GB using four 512-MB SDRAM
(synchronous DRAM) DIMMs.
For connectivity , the system supports four USB (Universal Serial Bus) connectors, a video
port, two LAN ports, and other standard features such as two serial ports, a diskette
drive interface, and two embedded IDE hard disk interfaces.
The system is fully compatible with Redhat Linux 6.2, Window s NT 4.0, and Windows
2000 Advanced Server OS.
This chapter contains a detailed description of the SGI 1100 server system components.

1: Chassis Description
Processors
Memory
The Pentium III processor implements Dynamic Execution performance, a
multi-transaction system bus, and Intel MMX media enhancement technology. Also, it
offers Streaming SIMD (Single Instruction Multiple Data) extensio ns, which are 70 new
instructions enabling advanced imaging, 3D, streaming audio and video, and speech
recognition applications. The Pentium III processor delivers higher performance than the
previous Pentium processor while maintaining bin ary compatibility with all previous
Intel Architecture processors.
This system board supports 133-MHz GTL+ host bus frequencies for Pentium III
processors running at 800 MHz and above.
The four DIMM sockets on board allow memory upgrade to a maximum of 2 GB using
four 512-MB SDRAM (Synchronous DRAM) DIMMs. (The DIMM sockets also allow
1024 MB for a maximum upgrade of 4 GB in future models.) For data integrity, the
default setting of the ECC (error-correcting code) function of the memory system in BIOS
is enabled.
Note: Only 3.3-volt SDRAM DIMMs should be used. 5-volt memory devices are not
supported.
The system board supports 133-MHz registered SDRAM; 66-MHz SDRAM is not
supported.
2 007-4047-001
System Chipsets
Server Works LE North and South Bridge
The Server W orks LE north chipset incorporated as a north bridge is in charge of the host
bus interfacing and memory bus control. The memory bus control supports PC-133
SDRAM registered ECC DIMMs up to a total of 4 GB. The north bridge provides one
64-bit PCI bus running at 66 MHz.
The south bridge subset provides the legacy ISA interface, USB port, AT A33, and System
Management Bus (SMB). The BMC (Bas eboard Mana gement Control) w as embedded on
the motherboard and connected with the south bridge to provide the ASM and RDM
functions and industry standard IPMI protocol.
LAN Subsystem
Another cost-effective feature for network solution is the integration of Intel’s 82559
10/100 Mbps Fast Ethernet controller which supports Advanced Configura tion and
Power Interface (ACPI) 1.20A-based power mana gement, wake on Magic Packet, wake
on interesting packet, advanced SMB-based mana geability, Wired for Management
(WfM) 2.0 compliance, IP checksum assist, PCI 2.2 compliance, and PC 98 and PC 99
compliance.
System Chipsets
Video Subsystem
The A TI Rage XL harbors 2D and 3D display capabilities that bring life to any multimedia
and work applications. It also supports hardware DVD decoding. With r emarkable color
depths and high resolutions of up to 1600x1200, it enhances every visual experience on
your system.
The on-board ATI Rage XL chipset comes with 4 MB of video memory.
Expansion Slo t
The system board has one 64-bit/66-MHz PCI bus slot with a riser card.

IPMI (Intelligent Platform Management Interface)
IPMI (Intelligent Platform Management Interface)
IPMI is an open standard hardware manageability interface specification. It provides an
architecture that defines how unique devices can all communicate with the CPU in a
standard way.
With IPMI, the CPU only communicates one event to the IPMI event log. The CPU only
“asks” what has changed since the last time it asked. Every device communicates
directly, through IPMI, to the event log, which is used to record, in a consistent way, all
status events for the unique device. This simplifies the agent-handling routine. The
system only needs a single agent, and it does not need to be changed when you change
from five devices to manage, for example, to six. And the system does not need to change
the way the CPU checks the event log when a new device is added to the system; it
always checks in the same way, whether there is one device or 100 devices. With IPMI,
use of the CPU is minimized, so overall system performance improves.
The following are the four elements of IPMI, each of which is described in the sections
that follow:
• Intelligent Platform Management Interface
• Intelligent Platform Management Bus
• Intelligent Chassis Management Bus
• Baseboard Management Controller
Intelligent Platform Management Interface (IPMI)
IPMI is the specification for the management controller command sets, including
command sets for sensors, event logs, and sensor data record access. It is also the
specification for the data formats, including sens or d ata records, event log entries, and
FRU inventory information. IPMI is also the name used for the overall standardization
effort.
Intelligent Platform Management Bus (IPMB)
IPMB is the I2C-based, multi-master bus used fo r intra -ch assis communication with
“satellite” management controllers. Here sensor devices and cards with IPMI bus access
can be added to the IPMI standard.
007-4047-001 13
1: Chassis Description
Intelligent Chassis Management Bus (ICMB)
ICMB is the RS-485-based inter-chassis management bus, based on IPMB. It is used for
common chassis and emergency management functions, including power and rese t
control, chassis status, events, and FRU inventory.
Baseboard Management Controller (BMC)
BMC is used to monitor baseboard temperatures and voltages , and to manage the system
event log and non-volatile storage for sensor data records. It provides a system software
interface to the IPMB.
