VMware vCenter Update Manager Sizing Estimator Posted

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
