Hello:
Here are a new document and tool about virtual capacity: "Demystifying Virtual Capacity, Part II".
Abstract: The previous work, “Demystifying Virtual Capacity, Part I”
is extended here to more that 2 virtual machines (VM). For solving the
virtual capacity it has been created a companion spreadsheet helper: “The Virtual Capacity Demystifyier”. This tool is presented here, and its usage is illustrated with several simple use cases.
Section I: The VM Capacity Space. In this part the guidelines for solving the generic N virtual machines capacity problem are exposed.
Section II: The Dashboard. The user interface of the spreadsheet helper is presented. The inputs and the outputs are conveniently explained.
Section III: Scenarios. This
is time to play with the tool. Several simple scenarios are presented,
but the main purpose of this section is to show how to use the tool by
example.
I hope you like it! Please, send me feedback as I would like to improve the tool in the future, as time permits...

I've always felt attracted to computer performance subjects: throughput, response time, sizing, bottlenecks, usage, capacity. I've not always seen clear, understandable and knowledgeable explanations on these subjects. With the arrival of the virtualization even more complexity is introduced: terms that represented constant values, like the machine capacity, gets blurred. What can be said about a virtual machine capacity if it is no longer a fixed value and may change from this hour to the next?
