OpenStack Swift is the Object Storage project within OpenStack. Alas, due to technical hurdles (eventual consistency, blocks <> objects, …) it is impossible to run Virtual Machines directly on Swift. You need a layer in between Swift and the hypervisor which can overcome these hurdles. This is where Open vStorage comes in.
Open vStorage is an open-source VM storage router. It is a software layer (called the VM Storage Router) in between Virtual Machines and storage backends. It allows to abstract the backend from the Virtual Machine and creates a uniform, single namespace across multiple hosts. These VM Storage Routers (VSRs) operate like a grid leveraging local flash memory or SSDs and any storage back-end (S3 compatible object store, (distributed) filesystem, NAS) to provide an extremely high performance and reliable storage system.
One of the supported Object Stores is OpenStack Swift. Open vStorage is the only solution to turn OpenStack Swift into block storage for Virtual Machines. Through a Cinder Plugin it allows to create and manage volumes directly on top of OpenStack Swift. Combining Open vStorage with OpenStack Swift allows to create a scale-out, performing, VM-centric storage platform which neatly integrates with OpenStack.
Speaker: Wim Provoost, Product Manager at Open vStorage
