Table 1-1. Major Metric Concepts (Continued)
Metric Description
Reservation Guaranteed amount of resources for an object.
The object does not start without this reserved amount. The
default amount is 0.
Entitlement Amount of a resource that a virtual machine can use based
on the relative priority of that consumer set by the
virtualization configuration.
This metric is a function of provisioned resources, limit,
reservation, shares, and demand. Shares involve
proportional weighting that indicates the importance of a
virtual machine.
The entitlement amount is less than or equal to the limit
amount. The only case in which entitlement is less than
provisioned is when the total provisioned amount is greater
then total capacity.
The entitlement metric applies only to virtual machines.
Rules: Entitlement <= Limit <= Provisioned
Entitlement >= Reservations
