  • 1.  How to design a DR plan with SRM on an active-active environment?

    Posted Jul 07, 2009 08:20 AM

    Hello all,

    I have one "two site Vmware cluster" of six host (VI3.5 update 3) with active-active configuration for the hosts and active-passive configuration for the storage. You can see the enviroment in picture

    in case of disaster on primary site I would like to failover the whole production on the recovery site.

    if the SAN is not disastered HA will take all the machines on the protected site --> in this case SRM will not be used.

    If "host AND SAN" OR "just SAN" get broken by the disaster I would like to design an SRM plan to automatically failover to the recovery site SAN and let the three hosts on the recovery site accessing the replicated LUN.

    Assumption

    • Syncronous replica task is in place, yet.

    • two virtual center (2.5 update 4) are in place: one on Protected and one on Recovery site

    • SRM has been installed on both the Virtual Center and site pairing is in place

    • Plugin for IBM DS8XXX has been installed

    Anyone have a similar configuration in place?

    any hints or best practice for this configuration?

    Thank you very much

    Are you taking about active / active scenario where the apps on the VM's are live on both sides?? then the answer is no with SRM , you would have to use some application specific DR solution..

    But if you taking about both datacenters being live and running VMs at the same point... the answer would be yes SRM would cover that. All you need to do is design your protection groups and recovery plans to include those VMs. Either of the sites would recover the other in case of a failure.

    HOpe this helps!!

    1) I will move this to the SRM forum so you will get more thorough responses.

    2) will the VC on the Primary site manage all hosts or will each site manage it's own hosts?

    Cause looking at you current setup you've got 6 hosts in 1 cluster which means you don't have any hosts in the "recovery site" cluster / VC which means a failover isn't possible.
