One possible architecture is shown in the figure below:
The Veeam MP for VMware installable back-end components are (coloured green):
|•||Veeam VE Service|
|•||One active Collector|
|•||One standby Collector|
Veeam VE Service must be installed on an Operations Manager Management Server. The Veeam UI and Collector(s) may also be installed there, or may be on separate machines.
Large environments may require several Collectors. In this case, you may use the Collector Auto-Deployment feature. This feature will use unattended installation to automatically deploy Collectors on Management Servers in an Ops Mgr Resource Pool.
For more information on the Veeam MP auto-deployment, see Installation Guide.
