Depends on what they want to do with the server? How much load will be on the server.
Having some experience with Milestone, the bottle neck is not only CPU, it's HDDs. I'm guessing that your bandwidth with this resolution for your cameras is around 1.5Mbps (perhaps less but we don't have more details), so a total of 75Mbps for the server to record/manage. I would put a XEON E3 series v3 or E5 series v2/v3 (4 cores is enough) and I would put 4x SAS 300GB HDD and then SATA drives for the archive storage. You won't have any problem to record and manage the installation. For Windows, go 64bit but no necessary Windows Server...only if it's Corporate in this case yes. For other version, you can go with Windows 7 Pro 64bit...it will be cheaper.
Hope this helps.
Yes, Corporate recording engine is better than Pro versions. I'm a bit amazed to see that Mike said that they could run 628Mbps streams on a single server, is this true? I mean all this on one server? I would be interested to see exact configuration and scenario for this...
As an old programmer for IBM and Honeywell and an ex Cisco trainer, I want to compliment everyone on this discussion. This is what I love about our forum. Technical and to the point. This should at least guide us in asking each vms co's the key questions prior to recommendations.
If you're going with Milestone, they have a server build form on their website. You plug in the number of cameras, model, desired fps, days storage, etc,--they respond by email with a suggested build. These are robust builds, I've personally found them to be overkill for us so we've scaled them back for our needs.
With 50 IP cameras you can bump up the cores and clock speed as discussed above, but you might want to also consider going with a machine that has two(2) Xeon processors. Dell 7610 workstation is a low cost 2 processor alternative or the D720 if you're looking for a robust rack mount solution.
There was some discussion about hard drives, I'm sure Milestone will suggest 10k or 15k rpm drives for storing the live video, but the archive video can be the cheaper 7.2K drives. Don't go cheap on the drives, video seems to toast the cheaper drives pretty fast (12-24 months).
I see some people noted the benefits of more cores when viewing video on the server. At 50 cameras, in my opinion, you should never be viewing cameras on the server. Buy separate dedicated viewing stations.

Per... 50 cameras, 2MP, H.264, 7FPS, as an example... This can be estimated at appx 100Mbits for the total throughput.
Depending on what else you plan to be doing with the system (ie viewing) will dictate if you need 6core.
If recording only...you do not need it.
If you anticipate having several clients pulling old data, you may want to consider a couple of SAS/High RPM drives.
Yep, you need a sas controller card that is different from the sata one.
