> CloudStack-managed storage was introduced into CloudStack with the new storage framework in 4.2.
> This allows CloudStack to create and delete storage repositories and datastores as needed.
> For 4.2 the VDI inside of an SR takes up almost as much space as is available in the SR (so there is a one-to-one mapping between an SR and a VDI). This is the same idea for datastores and VMDKs.
> The SR or datastore should be sized larger than its VDI or VMDK so there is space available for hypervisor snapshots that get stored on the same SR or datastore.
> How much larger can be determined by a cluster-level setting.
> For example, if you want a 10 GB CloudStack volume, the storage plug-in in question can create, say, a 20 GB volume on its SAN. 10 GB to be used for the CloudStack volume and an additional 10 GB for hypervisor snapshots.
