Well, my site was down a couple of times during the weekend. Had to buy a new server, since my old machine's power supply tanked and took the motherboard with it.
So, this week started on some serious hardware, a Dell PowerEdge 2900. The migration took a couple of tries, but it was mostly due to reconfiguration of RAID arrays. This beast has 10 SAS drive bays, so I opted for two RAID 5 arrays, mostly due to expandability.
Kudos go out to Alldea guys who suggested, tested, configured and helped me get the server in time (actually, I got it in 12 hours). Their service is flawless and if you are buying a Dell in Slovenia, give them a call.
We configured the machine with a quad core Xeon and left another processor slot empty. There are still two hard drive bays unattended and 8 RAM slots available. And since my old machine faulted because its power supply tanked, this one has two. Redundant ones.
It should give at least 5 years of service, me thinks.
