Dual-Core Opteron Processor Representation

Discussion in 'Windows 64bit' started by Microsoft News Groups, Feb 16, 2006.

  1. We are looking at purchasing some nice HP DL585 servers with 4 Dual-Core
    64-bit AMD Opteron processors. My question is, how will the Windows OS and
    Virtual Server 2005 R2 see this. Will it see it as 4 physical processors or
    8. This will determine whether we need enterprise edition for both the OS
    and VS software.

  2. There will be 8 processors visible in task manager, however, Microsoft
    licensing is per-socket, not per-core, so regardless of whether it seems to
    be 8 physical processors, with 4 sockets, you only need a 4-cpu license. If
    you get the x64 edition of Windows Server 2003 Standard, you can have up to
    4 dual-core CPUs and 32GB of RAM. Given that the DL585 supports a maximum
    of 32GB of RAM when using PC3200 DDR-SDRAM, it seems as though you can just
    about squeeze within the limits :)

    Now, non-Microsoft software may be licensed differently, but this applies to
    all MS software, including Windows, SQL, and anything else that is per-cpu.

    Also, your requirements will determine which version you need.

  5. A good box, you'll like it! It sees 8 processors for functionality, but 4
    processors for licensing. Licensing counts the number of sockets, not the
    number of cores.
