Doc Text:	To provide better flexibility for administrators on deployments with an assortment of storage backends, Block Storage now defines standard names for the capabilities, for example, QoS, compression, replication, bandwidth control, and thin provisioning. This means volume type specifications that will work with multiple drivers without modifications can be defined.	Story Points:	---

Description Sean Cohen 2015-08-31 21:45:38 UTC

Goals:
Provide standard capabilities from drivers that the admins can specify from volume types.
Improve the visibility of what policies are possible with your storage solution via Cinder client and Horizon.
Capabilities need to be exposed to the admin from Cinder, so that Cinder is not limiting what storage backends can do.
These capabilities can include, but are not limited to QoS, replication factor, bandwidth control, etc.
