Max mumber of cores in Windows Server 2003 Standard Edition

  • Hello.
    What is the maximum number of cores that Windows Server 2003 Standard Edition 32-bit support? I read that it will support four processors, but is that sockets or cores? I want to be able to take advantage of all 8 cores on a Dell 2900 with two quad-core processors.

    Thanks
  • Hello Jerry,

    windows 2008 standard edtion 32 bit only supports 4 sockets but up to 32 cores , but it depends on servers role in accordiance with http://www.microsoft.com/windowsserver2008/en/us/compare-specs.aspx , please also note the remarks at the end of table

    regards

    I'm not asking about 2008. I'm asking about Windows Server 2003.

    Perhaps I also need to know what server roles may play in this as well.

    Thanks
  • Hello Jerry,

    sorry for mismatch, I had several questions regarding 2008 ... anyway, on windows 2003 its the same idea; if see something like "windows 2003 32 bit standard supports up to 4 processors" it means the used sockets ( single processors), detailed infos regarding technical comparison windows 2003 server editions can be found at http://technet.microsoft.com/en-us/library/cc758523.aspx , windows 2003 32 bit standard support 4 way SMP , SMP is described at http://en.wikipedia.org/wiki/Symmetric_multiprocessing , 4 way smp is suitable for dual core cpus, so 4 cores can be used for applications, on your case with 4 quadcores with 32 bit standard the cores might be recognized , but you only can use 4 of them, if you want to use more than 4 cores , you have to switch to a windows edition (please refer comparision table) which can offer more than 4 way smp like enterprise or datacenter.

    the server roles , better say the options for using the server is also described in the server comparison list (please also refer link)

    I`ll hope that these infos will help you

    sry for the mismatch
  • So, I'm feeling confused. You say that "Windows 2003 is the same idea"; but it appears from what I'm reading that only 4 cores are accessed in 2003 Standard Edition, whereas 32 cores (4 sockets) are supported in the 2008 version. Just so I understand; if I have a dual quad-core system with 2003 Standard, 4 cores would always stand idle? I suppose I could pull up Task Manager and look at the CPU usages.
  • ... confused as myself when reading microsoft information sites .....
    In fact the idea is the same, but if you read the links and compared the content, you`ll see that windows 2003 std 32 bit only supports 4 way SMP and that means , in accordiance with the links, that only 4 cores are used, the other cores are not recognized or not used, be also aware that the ms links might not consider servicepacks, updates, patches .....

    Well, but I`m getting more confused that you are not already check your Task manager before about cpu usage .... anyway, if you have got other links with infos regarding you question , please share, additional infos might help to get a clear answer

    thks alot

  • I presume this is a valid test, looking at CPU usage in Task Manager. I don't know why it wouldn't be.

    I haven't checked yet because it's not installed yet.
  • Ok, I've installed Windows Server 2003 Standard Edition on a 2900 with two E5420 CPUs and downloaded a CPU stress test from http://weblogs.asp.net/kennykerr/archive/2005/10/21/428192.aspx. When I select all eight cores, Task Manager shows all eight cores at 100%. So, it sounds like we can interpret Microsoft's reference as sockets, not cores. Does everyone agree this validates my conclusion?
  • This article should help as well -- http://www.microsoft.com/licensing/highlights/multicore.mspx

    Processor from a Microsoft perspective means physical socket - no matter how many cores are on the processor socket.

    So Standard edition is up to 4 sockets ... Enterprise is up to 8 sockets, and Datacenter can go as high as 64 or 128 with a different SKU.

    Scott,

    Excellent! Thanks, that's the information I was looking for.

    Sorry, for a dumb question, I am new to hardware/servers.
    Is cores depends on Hardware or the OS?
    How to find number of cores on a windows server. please help me.
