ESXi 4 Datastore Limitations

Posted on 2011-04-24

I have a customer who is running a backup service for their clients and they currently have a couple of backup servers that they're thinking about migrating to ESXi because the hardware is outdated. Both of these servers are utilizing over 12TB of disk space on single volumes. Does ESXi support creating datastores of this size so I can migrate the physical boxes to VM's?

Any suggestions are welcome. If it's not a good idea or not possible let me know. Thanks.

    Accepted Solution

    No...the max datastore size is 2TB. You can create 6 datastores to accommodate the storage needed.

    Assisted Solution

    The maximum volume size is 2TB-512Bytes.  The max. datastore size is 64TB with extentes but no single volume can be over 2TB.

    If these are file servers I would look at other options such as SANs that support CIFS such as Netapp and others.

    You can create up to 32 extents to a datastore, for a max datastore of 64TB, but it's not a recommended VMware practice.
