Chapter 9: Capacity planning
Calculation settings
Any time you click Calculate, Virtualization Manager analyzes the load on the
resource container, calculates the remaining capacity, and then determines how
the usage profile would fit into the remaining capacity. You can modify the way
capacity is calculated in the Calculation Settings.
This section contains the following fields:
l Mem Wastage: Spare memory due to non-uniform VM resource
requirements.
l Mem Oversub: Amount of memory over-subscription as configured in the
VMWare Virtual Center.
l Sizing Target: Defines how the CPU, memory, and disk space utilization
values are used in calculations.
l Peak: Default setting which looks at the peak resource utilization.
l 95th Percentile: Ignores the peak, and calculates based on the 95th
percentile of resource utilization.
l 75th Percentile: Ignores the peaks and high spots, and calculates
based on the 75th percentile of resource utilization.
l
Reserved/Additional hosts
l
Failover Capacity
l Number to add: Performs calculations assuming more host resources
than currently used in the virtual environment. For more details, see
the What if I add more resources? use case.
l CPU (count): The number of CPUs per host.
l x Speed (MHz): The speed of each CPU (in MHz, not GHz).
l Memory (GB): Memory per host (in GB).
l Shared Disk (GB): Shared disk space per host (in GB).
