Efficient data storage is critical for large scale OpenStack cloud deployments. There are several shared file systems that can be used in an OpenStack cloud. These can be used to efficiently share data between Nova, Glance and Cinder, as well as provide storage for object and file based protocols with Swift and Manila. Enterprise features like copy on write file clones and file system snapshots, policy based tiering of data between storage classes, and intelligent backup schemes are important benefits that the filesystem backend can provide. In this presentation we describe these benefits that a shared file system can bring to your cloud architecture.
In this talk, we will provide an overview the of OpenStack storage components, and the benefits generally provided with shared filesystem storage. We will provide a detailed review of the features that Spectrum Scale provides and explain the benefits these can bring to your OpenStack cloud.
