Using OpenStack Glance Image Cache with Pure Storage

OpenStack deployments are rapidly gaining a foothold in many organizations across numerous industry sectors, but the one thing that affects all deployments is the time it takes to create a compute instance when using a source image file. The OpenStack Glance Image Cache feature provides a unified approach to the rapid cloning of Glance images, significantly reducing compute instance creation times.

This brief white paper discusses the OpenStack Glance Image Cache feature and how it has been integrated with the Pure Storage Cinder driver giving implementation details and examples of the volume creation improvements that can be gained.
