  • Theoretical, real, and realized hardware contraints.

    I have been trying to find ways to determine the amount of VMWare guests an ESXi 4.0 host machine can manage and have not been able to yield very much information.

    I'd like to start of with the certain hardware specifications I've got in mind.
    Dell PowerEdge R710
    Dual Quad Core XEON 5504 2.0Ghz
    24 GB 1333 MHz RDIMMS

    Storage:
    Dell PV MD3000i 10 x 300GB 15k SAS drives. iSCSI SAN over copper.

    Guest OS to consist strictly of WinXP Pro sp3 - 1024GB Ram, Single vCPU, 20GB HDD allotments.

    Given the variables above, at what point do we start running into performance based on the host's hardware. What sort of experiences have people had with this?

    There has to be a way to calculate theoretical maximums.

    Piece of string type question....

    Well, here are your configuration maximums: http://www.vmware.com/pdf/vsphere4/r...config_max.pdf so there's a start.

    You'll probably run into RAM constraints first unless you are using heavy CPU apps on your XP boxes, then you'll have CPU _and_ RAM constraints!

    Try the TCO calculator on the vmware site too

      This is exactly the sort of information I've been searching for. Thank you!
