I have a 200 machines all freebsd network that runs 24/7 with a mtbf of 15 years... how I got the numbers? well I have an "issue" every 3 or 4 weeks... (the machine hangs, stops, the power supply explodes....) the machines are aways on... if you count 200 machines and one machine crashes once every 200 days, I will have a 200 day running time on each machine... well I have almost once a month problem... that is 30 times 200 days -> 6000 days for each machine... the machines have now 3 to 5 years old... Now I am replacing the machines for AMD64 with mainboard ECS that proved the more reliable hardware... (asus k8v is also a good choice) (gateway is bad...) 98% of the machines are AMD, some are cyrix It continues to run even with the cpu cooler stopped by dust (yes!!! some machines are in rural areas, gas stations and have no way to offer maitenance) and I have not seen them for years... but sometimes the machines emails me.. (when they finally get dial up connection... and have some issue like: no space, no swap...) it is like sending them to mars... You can see some pictures of the running system on FreeBSD + gnome + windowmaker... at http://www.k1.com.br/images/sistemas these are old pictures, but you can have an idea. the new versions have more enhancements.... It is all coded in FreeBSD with python + gtk + postgres... and runs in windows too... Sergio
