Operational Limits of
vSphere Replication

To ensure a successful virtual machine replication, you must verify that your virtual infrastructure respects certain limits before you start the replication.
The following operational limits apply to vSphere Replication:
  • You can only deploy one
    vSphere Replication
     appliance on a
    vCenter Server
     instance. After you deploy another
    vSphere Replication
     appliance, during the initial configuration process in the
    VRMS Appliance Management Interface
    ,
    vSphere Replication
     detects another appliance already deployed and registered as an extension to
    vCenter Server
    . To proceed with the new appliance, you must confirm.
  • Each newly deployed
    vSphere Replication
     appliance can manage a maximum of 400 replications. See https://kb.vmware.com/kb/2102453 for more information.
  • vSphere Replication
     8.6 uses only an embedded database and requires additional configuration to enable the support of a maximum of 4000 replications. See https://kb.vmware.com/kb/2102463.
  • The maximum number of replications with 5 minute RPO can vary, depending on the network bandwidth and the change rates per disk.
    vSphere Replication
     8.6 can accommodate 5 minute RPO for 500 VMs.
