vCloud Air lets you direct storage for your virtual machines to either higher performance or lower cost storage tiers.

You can allocate virtual machine storage when creating virtual data centers and virtual machines or by adjusting their storage after you create them.

Note

While the total subscribed storage can be fully allocated to one or more Virtual Data Centers, some storage is reserved for operational overhead, including swap files and catalogs. This prevents you from fully provisioning the storage allocation to virtual machines.

To allocate storage to a specific tier when creating a virtual machine using a template, see Add a Virtual Machine from a Template.

To allocate storage to a specific tier when creating a virtual machine from scratch, see Create a Virtual Machine Without Using a Template.

To allocate storage from a specific tier to a virtual data center when creating the virtual data center, see Create a Virtual Data Center.

When users create virtual machines in the virtual data center, they can add can disks from the designated storage tiers based on the amounts allocated for the tiers.
