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
