  • Creating 2 TB + VMFS volume on local disk ?

    Hi All,

    I've got new Dell Server with 6x SATA 450 GB HDD, with RAID-5 i could get approx (6x450)-450 = 2.25 TB which I will split into the following:
    1. 2 TB of Local VMFS datastore
    2. the rest is for the ESXi system install itself.


    previously i tried to look for the unformatted LUN volume but the ESXi cannot find it ? (i think the limitation of the VMFS is still 2 TB per Volume)

    can anyone suggest me how to achieve this please ?

    Thanks,

    AWT

    Well, the obvious suggestion is to drop to 1.99 Tb and see if that is recognised. Will you really miss the 20.5 Gb?

      ah.. so i must format the existing disk using partition magic or Acronis disk director to make it

      251 GB
      1999 GB

      would that be possible ?

      i was thinking to create an extent (VMFS extent) but don't know how to do it or if it is not recommended due to the performance issue ?

        I don't know VMWare well enough to comment, unfortunately

        Is the 2TB proper TB (2048Gb) or Sales TB (2000Gb)?
        I would assume any limit would be the former

          thanks mate for your reply,

          how about if i make the 50 GB for the ESXi local install while the rest 2.2 TB is for the VMFS ? i was stuck in presenting this partition or LUN at the moment

          formatting the RAID 5 volume with 50 and 2.2 TB was OK under Acronis disk director suite but ESXi seems to ignore this empty LUN ?

            Albertwt,

            The following was taken from the VMware Configuration Maximums:

            Max Extent size = 2TB minus 512B
            Max VMFS size = 64TB minus 512B
            Max Number of Extents per Volume = 32 (32 x 2TB = 64TB)

              If I recall correctly the maximum is 2TB - 512kb with a block size of 8mb
