VMware vCenter Update Manager 4.1 Sizing Estimator

Simplify management of VMware vSphere by automating patches and updates. VMware vCenter Update Manager makes it easy to manage tracking and patching of VMware vSphere hosts, as well as selected Windows virtual machines. A new sizing tool, VMware vCenter Update Manager 4.1 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
–    Whether VUM 4.1 is upgraded from 4.0 and old ESXi upgrade bundles are still used
The following are the outputs from the tool:
–    VMware vCenter Update Manager 4.1 database deployment model recommendations
–    VMware vCenter Update Manager 4.1 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
