Will Stevens updated CLOUDSTACK-9278:
-------------------------------------
Description:
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.
