To deploy the Duplex OVA, install the Duplex OVA on two different hosts. Ensure that the hosts reside on two different clusters. Similar to the Simplex OVA, the Duplex OVA has one network interface configured in the OVA. An example host configuration for the Duplex OVA can be setup to include two virtual machine network connection type vSwitches, For example,
VM Network to use with the Communication Manager NIC 0 administration/call_processing traffic – connected to say vmnic 0
CM_duplication_link to use with the Communication Manager NIC 1 duplication link traffic – connected to say vmnic 1
Before you start the virtual machine, you must change the Communication Manager virtual machine settings to configure the second NIC. For information about changing the virtual machine settings, see Changing the virtual machine settings.
