No Longer in Development, Citrix have AutoScale now and this should be used in favour of this tool. The tool still works but I won't be fixing bugs.
Citrix had a product called SmartScale, this product was put out to pasture at the end of July.
The idea of PowerScale is to provide a solution with equivalent functionality.
The main decision making script is designed to be run from a Citrix Controller or VM with Studio installed on a scheduled basis.
Prerequisites:
Please make sure on your initial test runs you enable test mode, this will gather information but not perform any actions on the farm. This will also confirm that PSMAN access is working as expected.
