Use the storage of compute nodes as cache of remote cinder volumes
When virtual machines (VMs) do I/O operations with remote storage servers, local cache at the compute nodes is helpful to reduce I/O latency and improve I/O throughput. So we propose to add local cache support in nova to use the storage of compute nodes as cache of remote cinder volumes.

We propose to realize CacheGroup, which caches data on local storage devices of the compute nodes so that they can access data in their local cache instead of in the remote cinder servers.
You should not set a milestone target unless the blueprint has been properly prioritized by the project drivers.
