Clustering with one physical and one virtual node with GCO

Dear Experts,

Need some expert opinion on design recommendations. 

Planning to have Enterprise Vault  in clustering configuration with VCS locally with two nodes, one physical node and one virtual node on a Hyper-v guest AND global failover with GCO to a physical server without local failover at remote site.

The OS is Windows 2008 R2 or 2012 R2.

Storage is HDS HUSVM.

Kindlty let me know if this is working solution.

  • Hello

     

    1. VFC is only available in HyperV 2012 R2 (if I recall correctly). The guests can be either 2008 or 2012, but please remember that VCS does not support EV on Windows 2012 R2.
    2. I would disable the site/tasks schedule during the time you perform the DR drill. You can then run a manual archive of a subset of mailboxes to prove that it works, but not the entire thing (unless its no that much data and you've got enough bandwidth.)
    3. Good point, we usually cluster SQL along with EV using VCS. That way you can create a VBS / Recovery Plan and fail over everything together. Its part of the USP that you don't need SQL admins or other teams involved when you're using VCS. You just click switch (or execute for the recovery plan) and it all fails over together.
    4. There used to be a defined method listed in the VVR admin guide describing how to use checkpoints and backup/restore to perform the initial sync. I've not tried that in years, we usually just start the sync and let it do its thing.

  • Hi SymGuy-IT,

    Phyical to Virtual GCO clusters are fully supported.  We don't limit the use of Physical and Virtual servers with the Window's SFW/SFW-HA products.

    Thank you,

    Wally

  • An update which I got from support ... 

    Kindly note: Such a configuration, may be possible, however it is not supported if any problems arise. Symantec recommends that the Operating System, architecture are exactly the same on both nodes, for the application to run seamlessly. If this is configured, it may work. However, we will not be able to troubleshoot and support any problems which may arise due to such a configuration. 
    The query will remain same in case of Microsoft clusters.

    Recommended : To use either both physical nodes OR both virtual nodes.

    They are saying they dont support it .... :) ???

    Guys any ideas on this?

  • One of the major selling points for VCS is that it can do P/V configurations..... Product Management should comment on this as this is in direct conflict to what the sales presentations state.

  • The engineer called back and reconfirmed that it is supported :) Looks like h heard you ....

    Still he is emphasizing on the fact that the failover can go wrong if the resources are not available on virtual node. 

    """"I confirmed with Backline escalation and the physical + virtual node is possible. The failover will work. 
    The only implication we may have is with performance, which would lie outside the scope of cluster. Performance issues may arise because of host machine resource allocations. 
    However this is a supported scenario.""""

  • Haha, glad support can hear me all the way from the desert.

     

    Resource allocation must just be locked down from the hypervisor. Just ensure there is no sharing/pooling of resources. And get VFC up and running :)
