    P2V create a seperate disk for each volume question

    ablej Hot Shot

      When doing a P2V we noticed you now get the option to create a seperate disk for each volume. Wasn't this the default behavior before 3.0.3? What is the best practice?

       

       

       

      If you find this information useful, please award points for "correct" or "helpful"

          Hi,

           

          Before 3.0.3 it would create one vmdk containing all volumes of a server. We always create seperate vmdks for the disks of a virtual machine. Before 3.0.3 we were forced to use

          platespin because of this. Now vmware converter is also an option for us.

           

          Best regards

            Hi,

             

             

            Personally I do use the option to create a seperate VMDK for each volume. I prefer this option as it makes life much easier if you need to add space to a volume at a later date.

             

             

            One factor that should be taken into account is how many VMDK's you will have per LUN. This is also dependent on the amount of I/O generated by the VM's. If you have intensive I/O VM's keeping the number of VMDK's per LUN below 10 is a good idea. For high I/O I would stay below 16. As is the norm in Virtualisation balance is the key, if you have a few high I/O servers put these on their own LUNs then put lower I/O servers with them. This will balance it out.

              Prior to the latest version, P2V would attempt to create one VMDK per PHYSICAL DISK SET, not per server. (If you had say 2 disks mirrored and another 4 or 5 in a RAID 5) P2V would create a single VMDK for each disk set regardless to how many partitions there may be on them. Now P2V will let you a separate VMDK per each partition.

               

               

              in the past, to split them up, we would run separate "passes" to create the separate VMDK's and then reassemble them afterwards. (What a pain!)

                as stated before 3.0.3 it would create 1 vmdk and platespin powerconvert was a prefered option as it could split it out into additional disks, now with 3.0.3 now need to use powerconvert
