The implementation of an XSX School server is described on this page. You can also view the specification. The software running on this server is described in Trial1 Server Software.

Introduction

This is a server machine with a primary goal of supporting development of the School server/laptop software, including early trials. As this is a very limited production model (12-40 ?) and the design criteria are still undefined, flexibility wins out over cost. Off-the-shelf consumer PC hardware is being used.

Components

These are the particular components being used:

Motherboards

The mini-ITX form factor seemed to be the ideal in terms of meeting the requirements for relatively high processing power without a processor fan.

EPIA EN12000EG

The [EPIA EN10000EG] is based around Via's C7 processor, w. matching chip set.

Relevant features:

  • 1.2 GHz VIA C7 (686) processor
  • up to 1 GB DDR2 SDRAM
  • 10/100/1000base-T (VIA VT6122)
  • two SATA-1 ports (VIA VT6420)
  • two UltraDMA-133 IDE ports (VIA VT82C686)
  • four USB 2.0 ports (two off-board)
  • one PCI slot

Documentation

EPIA CN10000EG

The [EPIA CN10000EG] is also based around Via's C7 processor, w. matching chip set.

Relevant features:

  • 1.0 GHz VIA C7 (686) processor
  • up to 1 GB DDR2 SDRAM
  • 10/100base-T (VIA VT6103)
  • two SATA-1 ports (VIA VT6420)
  • two UltraDMA-133 IDE ports (VIA VT82C686)
  • four USB 2.0 ports (two off-board)
  • one PCI slot

Documentation

Memory

The memory used in all motherboards is 1GB of 533 MHz (PC-4200) DDR2 SDRAM, in a 240 pin DIMM. The particular parts are:


Disk Drives

Network Interfaces

Linksys

D-Link

Drivers

Ethernet

VIA Velocity

This is the driver for the 1000base-T interface on the EPIA EN10000EG motherboards.


Assembly Notes

Mechanical Assembly

Cabling

BIOS settings

Component Tracking

In order to determine if problems are related to a particular supplier of a component, we must track the deployed components carefully. Here is the table where we store this information:

Serial # Motherboard Memory Disk Net I/F Case Location
001 EN10000EG Kingston Seagate LNE AT wad's office 002 EN10000EG Corvair Seagate - - wad's office 003 EN10000EG AT

Where for Network interface cards:

  • LNE indicates the Linksys LNE100TX
  • DFE indicates the D-Link DFE-530 TX

and for Cases:

  • AT indicates the Athenatech A602BS, using supplied power supply
