--------------------------------------

             Summary: Storage Snapshot API for doing storage level snapshots
                 Key: CLOUDSTACK-9278
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9278
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
            Reporter: Syed Ahmed


The objective of this API is to enable storage vendor side snapshots of virtual disk when
using managed hardware as Primary Storage. When using the Primary storage plugins such as
SolidFire vendor,  each virtual disks is a LUN on the storage array. Using the storage array
snapshot capability benefits for performance and features sets supported by the storage vendor.

StorageSnapshot does not fit in the VolumeSnapshot API because it would not perform the same
tasks, a Volume Snapshot use the hypervisor capability to create a volume snapshot then extract
it and archive it into the secondary storage. The intent of a StorageSnapshot is to perform
a snapshot at the hardware vendor level, and keep it there for rollback purposes and disk
cloning. StorageSnapshot is more aligned with the VMsnapshot API capability but is intent
to be per virtual disk basis.
