I don't think anything prevents integrating Swift storage nodes with a NAS. Latency could be increased but depending on load, network capacity (shared vs dedicated), and use of caching, it is possible to achieve a good performance.
This link shows the integration of NexentaStor (a NAS/SAN integrated storage solution) with Openstack Nova: http://mirantis.blogspot.com/2011/11/converging-openstack-with-nexenta.html 2012/3/16 John Dickinson <m...@not.mn> > Generally, you would introduce latency in the storage system by using a > NAS attached to a storage drive.
