I am not the one who put them together and was not the one who decided to build them from scratch. They will be replaced by Dell PowerEdge SC1435 servers. The reason I want to go with Dell is because we aquired a few Dell servers about two and half years ago. Two of them are running our mail servers with a drbd/heartbeat configuration. They have been going strong for us for over two years and they are eight year old servers. They also have an uptime of 390 days. I took them down once when I did an upgrade. We aquired about 10 Dell servers total. I put Debian Etch on all of them. They all had a hardware raid. I had problems getting raid to work on most of the servers. I tried using the hardware and software raid. However, the raid on the mails servers worked without a problem. The network cards on these old Dell servers have been working great without any problems. However, they are old servers so they only have 100Mbit cards. We also have our firewall running on a small Dell server. No problems with it either. You can always check out the PowerEdge mailing list at http://lists.us.dell.com/mailman/listinfo/linux-poweredge.
