Efficient Image Management Using Cinder Volumes for Virtual and Baremetal Machines

Sign up or log in to save this to your schedule and see who's attending!

Image management takes a lot of time to upload and download the large disk image to Glance. By using rich features such as copy-on-write, backup, etc. provided by storage arrays, we can make the image management more efficient.

We are proposing improvement of Cinder volume backend for Glance. This realizes:

  • Storing image data in Cinder volumes (upload/download).

  • Sharing volume data among tenants.

  • Quick volume-boot of virtual and bare metal machines using copy-less volume creation from images.

  • Copy-less image creation from volumes for backups, image sharing etc.

To fully enable auto-scaling for applications, we need to boot instances as quickly as possible to respond the change of demands. By levareging the copy-on-write based volume creation, instances can be booted at once without copying image data. We also introduce quick boot for baremetal servers without copying images by combining with Ironic-Cinder support.
