Best Practice for DPM + Hyper-V Cluster + CSV + Fibre Channel Backups? RRS feed

  • Question

  • Hi,

    we´re evaluating Hyper-V and DPM at the moment. The test setup is as follows:

    - 1 FC SAN, created various Volumes, added to the Hyper-V Cluster as CSVs

    - 3 Hyper-V Hosts running as a Hyper-V Cluster with FC connection to the SAN

    - 1 Physical DPM Server with local Backup storage and also FC connection to the SAN

    As I understand, DPM installs the DPM Agent on the 3 Hyper-V Hosts. Within DPM I create a Protection group, selecting the Cluster itself and the VMs it should back up. The Backup process then connects via LAN to the DPM Agents on the Hosts and pulls the Data for the backups from the CSVs.

    Now since the DPM also has a FC connection to the SAN, I wonder if I could utilize that one somehow. This will be a huge performance boost (SAN is 8GBit/s, LAN is only 2GBit/s in a Team). I may be completely off with that. But could I just join the DPM Server to the Hyper-V Cluster also, so it has access to the CSVs? DPM will not be used to place VMs of course. But with direct access to the CSVs, would it pull the Data directly from the CSVs via FC?

    Or is this idea just plain stupid and it might work, but will break things when going into production? I just wonder if I could utilize that FC connection from the DPM Server to the SAN in some way to speed up backups and restore operations.

    Any input to this topic is appreciated. Thanks in advance :-)

  • Hi René :)

    The idea is not so bad ;-)

    You could join the DPM server as member to the CSV/Hyper-V Cluster - but it is important that the DPM server is in Pause/Drained forever so the DPM don´t take any connection from the Hyper-V Cluster.

    Another way to utillize the bandwidth in the FC is to install the DPM on one of the real Hyper-V nodes in the Cluster and map the Backup FC/SAN to the Hyper-V node.

    Kind regards :)

    Hi Rene,

    Did you ever get this working ?

    I´m sorry for the delayed Reply. Somehow I tend to miss the Messages the Forum should send to me or I forgto to enable the "Alert me" function.

    It´s been quite a while since that test and I remember that I tried to join the DPM Server to the HyperV Cluster, but it did not work. Joining to the Cluster did not work. Unfortunately I cannot remember what the Problem was. Maybe it had a different layout of Network Connections or it lacked some components I did not really wanted to install on a DPM Server. I´m sorry that I can´t remember the exact Problem, but in the end it did not work.
