VMware vCenter Update Manager is a component of VMware Infrastructure that automates patches and upgrades of ESX hosts, virtual machine Tools and hardware, Windows and Linux virtual machines, and virtual appliance. A new sizing tool, VMware vCenter Update Manager Sizing Estimator, is now available.


The following input parameters are used to estimate database size, patch store disk space, and temporary disk space:

       Feasibility for virtual machine remediation

       Number of ESX and ESXi flavors in the deployment

       Number of hosts, virtual machines, Windows distributions, average number of locales for Windows distribution, average number of different Service Pack levels for Windows distribution,

       Patch scan frequency for virtual machines

       VMware Tools upgrade scan frequency for virtual machines

       Virtual machine hardware upgrade scan frequency

       Patch scan frequency for hosts

       Upgrade scan frequency for hosts


The following are the outputs from the tool:

       VMware vCenter Update Manager 4.0 database deployment model recommendations

       VMware vCenter Update Manager 4.0 server deployment model recommendations

       Initial disk space utilization in MB for database, patch store, and temporary space

       Monthly disk space utilization growth in MB for database and patch store

       The upper and lower bounds on the estimation, assuming a 20% variance
