  • Configuring hard disk performance

    Hi
    I have a new disk for my virtual machines
    It is true to make 20G PARTITION each one for each virtual machine?

    This is going to give me better good performance?
    Thank you

    Re: Configuring hard disk performance

    No it is not true.

    It depends on the requirements of each and every virtual machine / OS / and a whole bunch of other stuff.

    I use the rule of thumb, that a Windows OS (for its system drive) does not need more than 20gb - and that is really overkill - it can actually do with 8gb

    Creating a separate partition for each VM will not guarantee better VM performance because they will still all be using the same physical HD

      Re: Configuring hard disk performance

      You said a new disk for virtual machine(s) I find for best performance is to have each vm on a separate disk. Also the size of the vm can be extended, so if it's too small u can always increase it.
      It helps to have fast ram also and ideally 2gb and up. (faster the better)
      Most cpu's are good, ideally anything above 2ghz (for none cpu intensive apps)

      I have vmware workstation, can run server/client well (vm's on same disk) although if i try 2 servers and one client things slow down.

      Basically the more resources u have the more vm's u will be able to run, so it entirely depends on your hw set up.
      It also helps to move the (host) paging file to a separate harddisk that isn't been used by the os or the vm's if possible.
      Also turn off services that aren't needed, turning off of visual effects, ect ect.

        If you're only going to use the disk for VMs, I see little point in partitioning it. If you leave it as one large partition, for a start you won't have the 20GB cap on each VM.

          Hi thank every one

          The 20g can be 30g of course it will depend the os and the use
          the question in fact I was considering to make one partition for each VM

          And yes I have 2G The partitions I will make at a new hd
          thanks

            My point wasn't so much that 20GB is too small, but that there seems to be little point to creating a different partition for each VM. You won't gain anything in terms of performance or reliability.
