3.3.3 Example
The following figure shows the vCloud Director configuration for Company2’s organization.
Figure 6. Configure Allocation Pool Screen
 
The settings correspond to Company2’s requirements.
*CPU allocation – This sets the CPU on the vSphere resource pool with a reservation and limit equal to the selected amount.
*CPU resources guaranteedThis is the amount of the vSphere reservation on the resource pool.
*vCPU speed – This sets a per virtual machine CPU limit to the specified amount.
*Memory allocation This sets the memory on the vSphere resource pool with a reservation and limit equal to the specified amount.
*Memory resources guaranteedThis is the amount of the vSphere reservation on the resource pool and on the individual virtual machines.
*Maximum number of VMs – This is a hard limit on the virtual datacenter for the total number of virtual machines that can be deployed. This can be useful to prevent overcommitment.
NoteThe vSphere resource pool that corresponds to the virtual datacenter has an expandable reservation on both CPU and memory Disabled.
These settings can be changed to meet the consumer’s functional requirements for performance and cost over time. In fact, changes to these settings can be made on the fly to increase resources. Depending on the number of vApps deployed, carefully consider the potential impact before reducing values.
