Architecting a vSphere Compute Platform : Designing a vCenter Server Ecosystem : 12.4 vSphere Update Manager : 12.4.1 vSphere Update Manager Configuration
   
12.4.1 vSphere Update Manager Configuration
To determine database patch repository sizing, use the VMware vSphere Update Manager Sizing Estimator at http://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vsphere-update-manager-60-sizing-estimator.xls. For instance, you can base a vSphere Update Manager design on the following assumptions:
No remediation of VMs
Remediate ESXi 6.0+ hosts
1 concurrent ESXi host upgrade
Patch scan frequency for hosts: 4 per month
Upgrade scan frequency for hosts: 1 per month
The following table provides a sample design configuration for vSphere Update Manager. As with other platform design considerations, the goal for a service provider, who deploys multiple instances of vSphere Update Manager across multiple platforms, is to maintain consistency in order to simplify operational management of the environment.

Note vSphere Update Manager does not address the issue of vCenter Server or Platform Services Controller component patching. Administrators are required to evaluate patches and updates to vCenter Server and the Platform Services Controller and apply those manually as required.
