Openstack Cinder Block Storage
==============================

Cinder provides an infrastructure for managing volumes in OpenStack. It was originally a Nova component called nova-volume, but has become an independent project since the Folsom release.

Sample pillars
==============

New structure divides cinder-api,cinder-scheduler to role controller and cinder-volume to role volume.
