This document describes the functional capacity when operating Mobility Optimized Networking (MON) feature in HCX.
The supported scale numbers are referenced per HCX Cloud Manager, irrespectively of the number of Site Pairings or Service Meshes deployed.
Considerations operating MON
There are several factors that limit the number of VMs that can have MON enabled at the same time while operating HCX for migration and network extension:
Default HCX Cloud Manager Resource Allocation: 4 vCPUs & 12 GB RAM
The supported numbers for MON in a HCX Cloud Manager are:
HCX version 4.5 or higher:
HCX version 4.4 and earlier:
Scale up MON
To improve MON scalability, resources on the HCX Cloud Manager must be increased to:
Extended HCX Cloud Manager Resource Allocation: 8 vCPUs & 24 GB RAM
The maximum supported numbers for MON in a HCX Cloud Manager are:
HCX version 4.5 or higher:
HCX version 4.4 and earlier:
Increase resources on the HCX Cloud Manager
The following procedure must be used to increase resource allocation on the HCX Cloud Manager VM.

Recommendations operating MON at scale
Refer to HCX Configuration Maximums
Contact your Cloud Provider regarding the availability of this procedure to scale up MON for HCX in your SDDC.
This option is currently NOT available in VMC on Dell EMC.
For Scale up requirements on VMC on AWS Cloud, please open a support case with Broadcom Support and refer to this KB article.
