Hi,

I am working on a Sahara doc bug:
     https://bugs.launchpad.net/sahara/+bug/1371360
     [DOC] Features overview suggests Cinders to increase reliability

I am doing some research for this update.

What are the use cases for Sahara + Cinder?
     1. Cinder-backed Sahara for persistent data
     2. Booting Sahara instances from Cinder volumes

Can option #1 be used in conjunction with existing plugin images?

Are there any docs on using Cinder volumes in place of ephemeral? 
(similar to the docs describing how to use Swift-backed EDP)

The Cinder integration test mounts a few volumes to instances but does 
not use them.

Thanks, Jacob
