MBG Engineering Guidelines, Release 8.0

13 Virtual MBG Considerations

Virtual Mitel Border Gateway (vMBG) is the MBG software and supported Mitel Standard Linux (MSL) operating

system bundled in a VMware Virtual appliance, to run in the VMware vSphere/ESX(i) hypervisor. The software is

packaged in Open Virtualization Format (OVF) for deployment into a VMware environment. Refer to the

virtualization sections of the MAS engineering guidelines for details and current best practices.

13.1Licensing

The standard MBG base kit cannot be used to run an instance of vMBG. The “Mitel Border Gateway Virtual

Appliance” base kit (part number 54005339) must be used instead. An existing base kit can be converted.

Warning: If the wrong base kit is used, the vMBG will have no licenses.

13.2Upgrades

A virtual MBG can be upgraded just like a physical MBG, by visiting the MSL Blades panel and downloading the

update from the Mitel AMC. Alternately, an MBG CD, available from Mitel OnLine, can also be used via the

VMware console.

MSL can also be upgraded either with the MSL ISO image available from Mitel OnLine, or by clicking on the

ServiceLink blade upgrade in the MSL Blades panel.

From time to time, Mitel releases new OVA files on Mitel OnLine. The OVA must be used for initial deployment of

a vMBG, but can also be used for upgrades by following the procedure below:

• Back up

the current MBG using the application's back-up button

• Deploy the new OVA

• Restore the backup file using the application's restore button

This procedure can also be used to convert a physical to a virtual MBG.

Alternately, a full backup of the MSL server can be performed, followed by deploying a new OVA, and then a

restore of the backup using the MSL server console.

13.3 Host Server Requirements

Hardware

The recommended minimum hardware to run vMBG on VMware vSphere/ESX(i) is:

• 2 x Intel Xeon E5620 (Nehalem quad core), 2.4 GHz, with HyperThreading

• 24 GB RAM

• 300 GB disk allocated to storage pool

See 12.5 Performance Characteristics and Limits on page 45 for more information on server capacities.
