An organization virtual datacenter requires storage space for vApps and vApp templates. You can allocate storage from the space available on provider virtual datacenter datastores.
Thin provisioning can help avoid over-allocating storage and save storage space. For a virtual machine with a thin virtual disk, ESXi provisions the entire space required for the disk's current and future activities. ESXi commits only as much storage space as the disk needs for its initial operations.
Fast provisioning saves time by using vSphere linked clones for certain operations. See Fast Provisioning of Virtual Machines.
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 any ESXi 4.x hosts, you must disable fast provisioning. If the provider virtual datacenter on which the organization virtual datacenter is based contains any VMFS datastores connected to more than 8 hosts, powering on virtual machines might fail. Make sure that datastores are connected to a maximum of 8 hosts.
- Select the storage policy to allocate and click Add.
- Enter the amount of storage to allocate.
- Select the Default instantiation profile from the drop-down menu.
This is the default storage policy used for all virtual machine provisioning operations where the storage policy is not specified at the virtual machine or vApp template level.
- (Optional) Select the Enable thin provisioning check box to enable thin provisioning for virtual machines in the organization virtual datacenter.
- (Optional) Deselect the Enable fast provisioning check box to disable fast provisioning for virtual machines in the organization virtual datacenter.
- Click Next.
