2 Right-click the organization virtual datacenter name and select Properties.
3 On the General tab, type a new name and description and click OK.
You can use the name and description fields to indicate the vSphere functions available to the
organization virtual datacenter, for example, vSphere HA.
Edit Organization Virtual Datacenter Allocation Model Settings
You cannot change the allocation model for an organization virtual datacenter, but you can change some of
the settings of the allocation model that you specified when you created the organization virtual datacenter.
Procedure
1 Click the Manage & Monitor tab and click Organization VDCs in the left pane.
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.
Edit Organization Virtual Datacenter Storage Settings
After you create and use an organization virtual datacenter, you might decide to provide it with more
storage resources from its source provider virtual datacenter. You can also enable or disable thin
provisioning and fast provisioning for the organization virtual datacenter.
Fast provisioning requires vCenter Server 5.0 or later and ESXi 5.0 or later hosts. If the provider virtual
datacenter on which the organization virtual datacenter is based contains ESX/ESXi 4.x hosts, you must
disable fast provisioning. For information about fast provisioning, see “Fast Provisioning of Virtual
Machines,” on page 120.
Procedure
1 Click the Manage & Monitor tab and click Organization VDCs in the left pane.
2 Right-click the organization virtual datacenter name and select Properties.
