DPM 2012 R2 Storage Pool Deduplication RRS feed

  • Question

  • Currently we are implementing a new install of DPM 2012 R2 in our environment.  We have been piloting an installation of DPM 2012 SP1 for a while now and have been happy with the results.  After initially getting the R2 installation up and running on all new hardware, including Quantum DXI storage configured as VTL and Quantum iScalar physical tape drive, I'm running into some issues.  I've searched a bit and found that DPM does not directly support using deduplicated storage pools running directly on Windows server, however the information regarding using third party controllers between DPM and physical disk storage is a little vague.  Has anyone found any information or know if it's possible to use the deduplicated storage as a DPM disk storage pool or is VTL the only real option to utilize the storage correctly?  The reason for asking, among a few others, is that according to DPM Exchange DAG mailbox databases cannot be backed up directly to tape.  In our case the mailbox databases are approximately 40 TB, which is a large amount of temporary SAN space to utilize as just a temporary landing place for data transfers.

  • Hi,

    DPM 2012 SP1 and DPM 2012 R2 only allow the flexibility to protect volumes with deduplication featured enabled. However you are correct you cannot enable Windows Server 2012 or Windows Server 2012 R2 disk dedupe feature on DPM storage pool volumes. The first below link outlines the supported configurations for DPM storage disks. The second link outlines additional information
    on DPMs flexibility for protecting duplicated volumes.
