Early 2015 Frank Denneman and I had a discussion during a flight to San Francisco. We came up with this concept for Resource Pools where the number of shares would be determined by the number of VMs and the priority of the pool. In other words, we wanted to avoid the dilution of shares in an environment with resource pools and basically solve the resource pool pie paradox problem described here. We worked with the DRS team on describing the concept, we filed a patent for it and got the patent granted in 2019. Today I am happy to share that the feature made it into a release and will be part of vSphere 7.0.
