Dual/Quad Xeon 350Mhz maybe, unless you were going to run OpenBSD under VmWare on W2k3 or something :-S > If you have faced some thing similar, would you mind replying me in pvt? > > Thanks a lot for your time and attention. Focus your dollars on good RAID/disk hardware. What the future holds for AMI RAID controllers under OpenBSD is good. The only one of those servers that I could see needing a decent amount of cpu-power would be 5, and thats all dependant upon what kind of scripting etc. the machine is doing. Are all 15k users going to be on simultaneously? In my environment we have 1600 users, but also 24 hour usage, so you never see more than 800 or so on simultaneously. That means you only *have* 800 users really. Might I also recommend backup servers? It appears as though you don't have that figured in. Nothing is totally fail-safe. What if the logon, or db server crashes; can you afford the downtime?
