Database Servers Ordered
The base model is an Opteron powered 1U server with 1GB of RAM, 1 Gb card, and a SCSI adapter on-board.
We upgraded the RAM on each of these to be a mere 4GB each.
We went from the base model Opteron to dual Opteron 275's (dual-core) in each machine.
Hard Drive Upgrade
Databases are only as reliable as their drives, so we went with mirrored storage.
I also added in a second NIC for total redundancy (one for each switch).
IBM seems to have more confidence in their servers than Dell, because for a little less than what Dell's 3 year warranty was we're getting 5 years on the IBM's with 24x7 4 hour response (instead of the 9x5 4 hour that Dell is giving us). The 24x7 seemed more appropriate since I can only afford 2 of these servers instead of the 3 I got from Dell.
Let the Fun Begin
It'll be interesting to see what I can get working to make the websites scream. Hopefully, I can make it totally fail-safe and have next to no downtime once they're all up and running. Anyone with advice on making for a fool-proof, bullet-proof system let me know. I'm excited about moving form our underpowered system and starting to do some real number crunching in a scalable fashion. :-D
