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
       term 'expected value', please refer to: http://en.wikipedia.org/wiki/Expected_value.

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
