3.1.3 Example
The following figure shows the vCloud Director configuration for Company2’s organization.
Figure 4. Pay As You Go Settings
 
The settings correspond to Company2’s requirements.
*CPU quota – Provisioning stops when the virtual datacenter has reached the configured amount. For example, if this is set to 100GHz and all virtual machines are provisioned with 1GHz CPUs, when 100GHz worth of CPU is deployed no more will be provisioned. This can be a combined total based on the number of vCPUs on each virtual machine.
*CPU resources guaranteed – This sets a per virtual machine reservation on CPU based on a given percentage.
*vCPU speed – This sets a per virtual machine CPU limit to the specified amount.
*Memory quota –Setting a limit prevents provisioning of more virtual machines when that limit is reached.
*Memory resources guaranteed – This sets a per virtual machine reservation on memory based on a given percentage.
*Maximum number of VMs – This is a hard limit on the organization virtual datacenter for the total number of virtual machines that can be deployed. This can be useful to prevent overcommitment.
NoteThe vSphere resource pool expandable reservation for both CPU and memory should be Enabled.
These settings can be changed to meet the consumer’s functional requirements for performance and cost over time.
