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 Ethernet chipsets that supports WOL (wake on LAN) for better
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, Windows 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
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) extensions, which are 70 new
instructions enabling advanced imaging, 3D, streaming audio and video, and speech
recognition applications. The Pentium III processor delivershigher performance than the
previous Pentium processor while maintaining binary 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.
Memory
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.

System Chipsets
007-4047-001 3
System Chipsets
Server Works LE North and South Bridge
The Server Works 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, ATA33, and System
Management Bus (SMB). The BMC (Baseboard Management Control) was 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 Configuration and
Power Interface (ACPI) 1.20A-based power management, wake on Magic Packet, wake
on interesting packet, advanced SMB-based manageability, Wired for Management
(WfM) 2.0 compliance, IP checksum assist, PCI 2.2 compliance, and PC 98 and PC 99
compliance.
Video Subsystem
The ATI Rage XL harbors 2D and 3D display capabilities that bring life to any multimedia
and work applications. It also supports hardware DVD decoding. With remarkable 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 Slot
The system board has one 64-bit/66-MHz PCI bus slot with a riser card.
