Resource pools created to support Pay-As-You-Go organization vDCs always have no reservations or limits.
Pay-As-You-Go settings only affect overcommitment. A 100 percent guarantee means no overcommitment is
possible. The lower the percentage, the more overcommitment is possible.

Allocate Storage
An organization vDC requires storage space for vApps and vApp templates. You can allocate storage from
the space available on provider vDC datastores.
Thin provisioning can help avoid over-allocating storage and save storage space. For a virtual machine with
a thin virtual disk, ESX/ESXi provisions the entire space required for the disk's current and future activities.
ESX/ESXi commits only as much storage space as the disk needs for its initial operations.
