The capacity badge represents the remaining capability of your virtual environment to accommodate new virtual machines.

The remaining virtual machines count represents the number of virtual machines that can be deployed on the selected object, based on the current amount of unused resources and the average virtual machine profile for the last "n" weeks. The remaining virtual machines count is a function of the same compute resources of CPU, Mem, Disk I/O, Net I/O, and Disk Space that are used to calculate the Time Remaining score.
