  2. Right-click the organization virtual datacenter name and select Properties.
  3. On the Allocation tab, enter the new allocation model settings and click OK.

    Option

    Action

    CPU allocation

    Enter the maximum amount of CPU, in GHz, to allocate to virtual machines running in the organization virtual datacenter. This option is available only for Allocation Pool and Reservation Pool allocation models.

    CPU resources guaranteed

    Enter the percentage of CPU resources to guarantee to virtual machines running in the organization virtual datacenter. You can overcommit resources by guaranteeing less than 100%. This option is available only for Allocation Poll and Pay-As-You-Go allocation models.

    vCPU Speed

    Enter the vCPU speed in GHz. Virtual machines running in the organization virtual datacenter are assigned this amount of GHz per vCPU. This option is available only for a Pay-As-You-Go allocation model.

    Memory allocation

    Enter the maximum amount of memory, in GB, to allocate to virtual machines running in the organization virtual datacenter. This option is available only for Allocation Pool and Reservation Pool allocation models.

    Memory resources guaranteed

    Enter the percentage of memory resources to guarantee to virtual machines running in the organization virtual datacenter. You can overcommit resources by guaranteeing less than 100%. This option is available only for Allocation Poll and Pay-As-You-Go allocation models.

    Maximum number of VMs

    Enter the maximum number of virtual machines that can be created in the organization virtual datacenter.

    These settings affect only vApps that you start from this point on. vApps that are already running are not affected. The usage information that vCloud Director reports for this organization virtual datacenter does not reflect the new settings until all running vApps are stopped and started again.
