NAME
powernap_calculator - estimate the expected power savings using powernap in a cloud
environment
SYNOPSIS
powernap_calculator [-h|--hosts NUM] [-p|--guests-per-host NUM] [-g|--guests NUM]
OPTIONS
-h, --hosts NUM
Number of physical host systems in your cloud.
-p, --guests-per-host NUM
Number of virtual machine guests allowed to run on each physical host system
(often, this is equal to the number of CPUs in the host system)
-g, --guests NUM
Number of guest virtual machines running in the cloud at a given instant.
DESCRIPTION
This utility will use statistical analysis to determine an expected value of power savings
within a cloud environment using powernap. For more information about the statistical

EXAMPLE
If your cloud consists of 8 hosts, each of which can run 4 guests, and you're currently
running 16 guests, you can see your power savings expected value with:
powernap_calculator -h 8 -p 4 -g 16
