Athenaeum Server Upgrades

So, I have a server, its name is Athenaeum. It is used as a file server for storing media, mostly video. It was created using parts from my old computer and Mitch's old computer and extra hard drives I had lying around. It had seven hard drives, one being the system drive and 10GB, the other six hard drives were spanned together forming a 220GB drive. It was powered by a pretty decent 420 watt power supply.

That was 3 months ago. Now, that 220GB is full, less about 700MB right now. Plus I found out the array was dangerously hot. I had more hard drives for it but after doing some math, I calculated that the power supply was prolly close to maximum capacity. So, some upgrades were in order for the computer.

So, 3 80mm fans later, a 250 watt AT power supply, a 120 volt relay, and some wiring later, the server is all upgraded. It now has an extra 60GB of disk space, which should hold me over for a little while. It is now running dual power supplies as well. I've put up a photobook of upgrade pictures.

The way the new power supply is wired in is so that it is slaved off the main one. The +12VDC that comes out of the power supply triggers the 120V relay that is now in place of the switch that was on the second power supply. So when the main PS turns on, the second power supply is powered on. If you look at the pictures, a diode has been placed accross the trigger contacts so that the spark that is generated when the relay is powered on doesn't cause feedback back into the main power supply. Now the secondary power supply is powering the case fans and the new hard drives. I also installed a new IDE controller card in the computer so I could plug the new drives into. I have support now in the server for 12 IDE devices, with 2 currently free.

It was a fun little project to do, the next one with this server will probably to add space for more hard drives. But I don't know at this point. I might just replace some of the smaller hard drives with bigger ones.
