SRM and Zerto

  • Hi, we are implementing Vmware SRM for Local failover onsite and currently have Zerto setup to replicate offsite to a 3rd party.  The question is for Vmware SRM it relies on multiple VCenter servers.  Can you still use Zerto in a multiple Vcenter setup and will zerto still work if a VM fails over locally to the seconday VCenter server?

    Thank you in advance

    Why bother with SRM when you got Zerto as well? You can do multi-stream to a secondary vCenter and to a 3rd party site at the same time.

    To answer your question, on the secondary site you would deploy a ZVM as well, and configure it with that second vcenter, same setup as you did at the primary site. After that is done, you just PAIR the two sites together, and it will become a failover site in the list of available failover sites. You would have to login to each individual ZVM server to choose a source VM, in case you are moving data in more than one direction. Licensing will automatically be shared between the two ZVMs once you pair them.

    In our situation we replicate from our prod datacenter over to Azure, as well as local replication for some test labs (one vCenter), and when we acquire companies, we deploy a ZVM in their datacenter with their vCenter and replicate from them to us for migrations. Very powerful tool.

    If you insist to continue using SRM, and fail over with SRM instead…Zerto will most likely think the source VM is gone and allow you to failover via Zerto as well (obviously unnecessary if SRM was already used). This you would have to test. Last company we bought used SRM in their environment and we deployed Zerto there for migration and it worked side by side without issue, but we never had a need to fail anything over with SRM so don’t know how it would work in your specific situation.


    Also take into account that VMWare SRM software replication isn’t supported with Zerto, as SRM replication locks virtual disks.
