Tool: VMware Update Manager 4.1 Sizing Estimator

While VMware has planned to drop the guest operating systems patching capability from Update Manager (VUM), it seems to continue investing in the product. 
The company just released a very handy tool for VUM capacity planning called Sizing Estimator.

Sizing Estimator can forecast VUM 4.1 database size, patch store disk space, and temporary disk space by checking a number of parameters.
Its output includes:

  • VUM database and 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

Definitively recommended.
