My system is a distributed cluster of 14 older systems that never goes

nodes in the network) and access the entire cluster (or individual

Fun, fast, and reliable, I agree. But cheap? 14 systems at 300 watts per system (typical power supply rating) comes to 4200 watts of constant draw. That's a pretty hefty electric bill.

An average older system will not consume 300W. My new system equipped with AMDx2 4200, Areca-raid with 5 hdds uses about 220W in average. Together with an older FSC Primergy 470 (Dual PIII-500 + 3 SCSI hdd RAID) and an older PII als Firewall they are using about 400W all together. Included are 19" TFT monitor and the small fry like switch, cable modem etc.

I heard the same screams in our company from my boss when the electrician told him our ups was underpowered (he assumed 400W each server). We now have a few servers more in the rack and the ups load is still safe at about 57%.

Though I agree in general, a few fast machines will consume less energy than a lot of small systems.
