  • * indicates up to 8 vCPU are supported.

  • ** indicates the capacity was validated using VMware ESXi, the network used between physical host is 10 Gigabit Ethernet. SIP traffic generators were used to simulate real traffic.

Note: Backing up data and execute config_mirror might slow down traffic flow; hence, Mitel recommends that you back up data during low traffic periods.
