There are numerous reasons why you would want your Swift Object Server to also host a NAS server.
But whether you are talking Nova volumes or Swift Objects, you would generally want the Volume Server or Object Server to access those "directly" rather than via NAS over a general network connection. There are a lot of trade-offs however. Realistically large JBOD arrays are not truly "direct attached", they Are being accessed over a FC or SAS network. Currently SAS is a more cost effective method of connecting A server with a large number of targets. 10 GbE networking might slightly outperform SAS, but the cost per port is higher. In addition to the connectivity issues, you would generally want to avoid adding an extra layer of name Resolution before you reached your real data. _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
