  • 2nd CPU

    Hi,
    Running SBS 2003 std. on ML350 ( HP ).

    I'd like to add a second CPU ( XEON 2.8 ).

    What's the procedure ?


    Tnx

    Re: 2nd CPU

    Try reading this article

    http://support.microsoft.com/default...b;en-us;234558

    It is for Windows 2000 but i can't see it being that much different for 2003.

    Please note ths i have not and will probably never try this so i can't gurantee it will work.

      Re: 2nd CPU

      IIRC if you open up Task Manager, you see the CPU channel as if you already have 2 CPU's. Why do I mention this? Because if you add another CPU, then the system will believe you have 4 CPU's. That may put you into an unsupported/unlicensed position since SBS is only licensed to a maximum of 2 CPU's.
      That doesn't mean it doesn't work. Again IIRC, you get a warning but it doesn't block you. But if you ever need to call CSS/PSS for support, then they may decide you are not entitled.
      TIA

        Have a read of page 5, Section 4. http://download.microsoft.com/downlo...ad_Windows.doc

        The current Windows operating system licensing model for HT-enabled systems is to require a processor license for each physical processor.
        So, if I read this correctly, a 2nd HT CPU in a SBS2003 system will be legal. You will have 2 Physical processors but 4 Logical one. Can someone smarter than me read the article and confirm this.

        Dual core CPUs however, may be different. (Haven't found an article on that yet.)

        Sorry, just realised I have taken this slightly off topic. Might be worth splitting the thread?

        1 1 was a racehorse.
        2 2 was 1 2.
        1 1 1 1 race 1 day,
        2 2 1 1 2

          Just read the doc and have to agree with biggles on this on.

          As SBS2003 is HT aware it will treat the logical processor as it is, not a second physical CPU.

          Now if it was SBS2000 that would be a different matter. It is not HT aware thus would treat the logical processor as a physical processor thus limiting you to one single HT CPU per system.

          At least that is my spin on it.

          If you are really concerned turn off HT in the BIOS.

            Windows Small Business Server 2003 supports up to two physical CPU processors and up to four virtual CPU processors. For more information about support for multiple CPU processors, consult the Web site of your hardware manufacturer

            from: http://www.microsoft.com/windowsserv...eneralfaq.mspx

            Anyway, I've added the second CPU without problems.

            Tnx.

                Didn't...

                Just installed it and the OS did the rest.

                  I have done this procedure also and there are no issues with sbs2003 and running dual xeon processors. Works great.
