[Openstack] [swift] account and container with separated servers

It depends on your cluster, but there are good reasons for doing so. Since Swift's background processes are constantly scanning the drives to check for errors, processes like the object-auditor and object-replicator can clear out the system's page cache simply by scanning the local filesystem's inodes. If you have account and container servers deployed on separate machines from your object servers, requests to an account or container will be more likely to have the data in the local page cache. This can raise the overall object write throughput of your cluster.
