dotalton 375b656658 Clarified and added more information on storage drivers.
Updated this to reflect the availability of multiple storage
backends, and how backends work in general. Added exaples of backends.
Explain how the backend could determine where you are able to run
the cinder volume service.

<title>Add the Block Storage service</title>
<para>The OpenStack Block Storage service provides block storage devices
to guest instances. The method in which the storage is provisioned and
consumed is determined by the Block Storage driver, or drivers
in the case of a multi-backend configuration. There are a variety of
drivers that are available: NAS/SAN, NFS, iSCSI, Ceph, and more.
The Block Storage API and scheduler services typically run on the controller
nodes. Depending upon the drivers used, the volume service can run
on controllers, compute nodes, or standalone storage nodes.
