I am trying to re-purpose an old backup server for backups from my VMWare machines. We are running the free version of VMWare ESXi 4.1.0. Looking around I discovered that the only free iSCSI SAN software that works for my configuration is OpenFiler (and possibly FreeNAS). So I have set up OpenFiler system with a 6.94TB LUN.
However when I attempt to create a datastore that big, VMWare maxes out the LUN at under 1TB. It looks like there is a limit of 2TB in the documentation. My goal is to attach this storage on a windows 2008 X64 vm that is running Backup Exec. (Because in the free ESXi I can't use the storage API).
I am looking for suggestions on how to attach this storage. Oh and what obvious facts am I missing as a storage nube?
