Basic Requirements - VMware

Note: MX-ONE Virtual Machines requires minimum ESXi 5.5 Virtual Machine version 10, but Mitel recommends ESXi 6.7.

Mitel recommends the use of thick provisioned lazy zeroed disks when deploying Consolidated or High Availability setups. Fault Tolerance setup requires thick provisioned eager zeroed.

When running VMware HA and FT, it is necessary that sufficient server resources and priority are configured for MX-ONE guest machines in a cluster in order to avoid that any failed virtual machine have standby resource precedence over the MX-ONE guest machines in a failover scenario. Such a situation would cause real-time traffic disturbances in a customer environment, which would defeat the purpose of the High Availability or Fault Tolerance.

The MX-ONE 7.x and later OVA default setup provided by Mitel is shown in the following table. .

Note: VM requirement in the following table needs to be changed according to the system size (number of devices per server). See the tables MX-ONE Guest Machine Requirements for adjusting the requirements appropriately.

VMware ESXi version	ESXi 5.5 and later
vCPU	2
CPU Reservation	1000 MHz
Memory	6 GB
NIC driver	VMXNET3
VM Hard disk space	100 GB
Virtual Machine Version	10

In general, it is always recommended to follow VMware recommendations for host server configurations, but when running MX-ONE in a virtualized environment, the minimum configuration for the consolidated and high availability setup is described in the item MX-ONE Guest Machine requirements.

Mitel recommends two or more virtual CPUs. If the MHz need exceeds 2500, then three virtual CPUs should be configured. If the MHz need exceeds 3500, four or five virtual CPU should be configured and so on.

Note: Partners and customers are required to customize the default OVA setup based on the specific MX-ONE application and system size, as detailed in the MX-ONE Guest Machine requirement tables. While the VM's default disk size of 100GB cannot be altered in the OVA image, a new virtual machine can be created using the MX-ONE_7.x_Server_Template.ovf template. This allows for disk size adjustments during the installation from the recovery image.

Note: The default setting cannot be changed since we have delivered 120GB ssd disk. A workaround is done to use the template from the recovery image (MX-ONE_7.x_Server_Template.ovf) to create a new virtual machine and to change the disk size to appropriate value. Install the virtual machine from the recovery image.
