Rackspace Cloud Block Storage is launching soon. I'd like to describe briefly what the team built, what parts Lunr and OpenStack play in the product, and then dive into some lessons learned in the design and development of a scalable commodity hardware based storage solution and interfacing with nova-volumes, cinder, and the xen storage manager. After that, if anyone is still awake, probably end the talk with a quick wrap up highlighting some of the areas we think OpenStack volumes has the biggest opportunities to improve and with the communities blessing how we can contribute!
