Traditional a Sextant is a tool used by sailors to navigate the oceans and ports of call. SEXTANT0x#### dose just that for communications, acting as both the firewall, and gateway to the outside world.

When computers fail, people generally sit back and acknowledge how they make life easier. When they pick up the phone and get no dial tone, they want blood (CTI Magazine). Sextant had to work, even if the world was going to hell in a hand basket.

A fleet of antique 80MHz 486s with more ram on there IDE accelerator cards then on the motherboards. A prototype for what would become. Everything was done to these computers, running with no cache, PCI buss over/under clocking, and RAM size/speed tests. these computer got tormented with endless torture tests, ranging from running 24/7 with all there fans unplugged in a self cleaning oven, to being subjected to hours of Tesla-Coil discharges inside there cases while running. yes there was a sledge hammer involved in some tests.

There was nothing left to salvage from that Server-Combat! other then the knowledge learned. So long as the operating system can run without virtual RAM or a "swap-file" reliably, the Cache size/speed, memory MHz/CL#, and PCI bus makes or breaks there ability to serve. Over sized heat sinks survive fan failure better then small ones. All cables need to be secured well away from moving parts. And never count on the hard drive working at the end of the day.

An accumulation of lessons learned from Server-Combat! A proxy server from hell. A 47 watt 450MHz k6-3 processor with a ground-strapped AthlonXP thoroughbred heat sink. The Motherboard of choice was supposed to have ALL 2Megs of L3 cache on it, arriving with a single Meg. Nothing goes on the PCI buss except the two network cards. No caching is done on any hard drive, System-RAM-Drives are a thousand times faster. The Power supply was selected to operate directly from a square-wave inverter.

SEXTANT0x001F had been running 24/7 from December 1999 to November 2007, threw countless power outages, floods, direct lightning strikes, and hail storms. It has been fun changing dead fans, and cleaning the Server without shutting it down.

This was supposed to be the replacement/upgrade for 0x001F. an ultra low watt AMD Sempron64 processor with overkill cooling, and identical L1/L2 cache. Substantial memory upgrade, for faster web caching, and larger DNS tables.
