The Windows Server 2003 family supports single or multiple CPUs that conform to the symmetric multiprocessing (SMP) standard. Using SMP, the operating system can run threads on any available processor, which makes it possible for applications to use multiple processors when additional processing power is required to increase the capability of a system. New features include SMP locking performance, improved registry performance, and increased Terminal Server sessions. Designed for mission-critical applications, Windows Server 2003, Datacenter Edition supports new systems with up to 64-way SMP. The support for over 32 processors is only available with the 64-bit edition of Windows Server 2003, Datacenter Edition.

Microsoft also offers a 128-way SKU for Windows Server 2003, Datacenter Edition so Windows can run on a 128-processor computer. However, the largest partition supported would be 64 processors.

Alien

from Overview of Windows Server 2003 R2 Datacenter x64 Edition
...
Multiprocessor Support - Up to 32

however - from Windows Server 2003 Datacenter Edition with SP1 for Itanium-based Systems
...
Multiprocessor Support - Up to 64 per partition

Me thinks we should be given the points...

Wrong Answer.
64bit edition != Itanium
"normal" 64 bit = 32 processors.

I too think that there should be points refund.

With my outstanding search engine skills, I found the Windows Server 2003 Datacenter Edition site that has this:
"The high-end Windows Server scales up to 64 processors".

It's been already said:

from http://www.microsoft.com/windowsserver2003/64bit/x64/datacenter.mspx

...(Windows Server 2003 R2 Datacenter x64 Edition supports up to thirty-two CPUs on one server)...

at least half a point;-)

Itanium is a 64 bit processor. The question did not specify x64, it merely said 64 bit windows and the software supports 64 processors. It may be nitpicking, but the first URL given says 2 to 64 CPUs, and then contradicts itself in the table with a limit of 32.

Windows 2003 is built to run 64 CPUs.

I dunno about this answer, as http://www.microsoft.com/windowsserver2003/64bit/x64/datacenter.mspx has all of the points in your question and states 32 processors. Could the documentation be incorrect?

I don't like being wrong but I also like knowing when I am wrong so I can learn. BigGrin

that URL, for x64, has two conflicting items. There is a para that says: "Windows Server 2003 R2 Datacenter x64 Edition supports up to 2 terabyte (TB) of RAM (with Service Pack 1) on 2- to 64-way. Supported processors include:" (Emphasis mine). Below that in the table it shows a limit of 32 CPUs.

My understanding is that teh W2K3 Datacenter, x64 is limited to 32 CPUs, but I see a whitepaper (http://www.microsoft.com/servers/64bit/whitepapers.mspx) on deployments, that says up to 64 CPUs. I'll ping MS and try to get a more definitive answer.

This one, on Itanium support, (Windows Server 2003 on Itanium), shows 64 CPUs.
