The LUN's from EMC storage is presented to both these nodes. I was thinking, we present LUN's from either storage to the gluster nodes present on either sites. These LUN's will be then mounted on the gluster nodes (bricks) using xfs filesystem. Then I create a gluster volume using them and mount that volume on the application servers (2) that's present on either site. Both these sites are connected using a dedicated 2GBps dark fibre. I'm not sure this makes a whole lot of sense... I don't know much about your EMC storage setup, but it seems to me you're just trying to pass it through gluster for no particular reason. If you've got some sort of EMC san, I think it makes sense to use that directly. You can think of gluster as a SAN replacement, not a layer on top of an existing one. But this is all just speculation based on what I'm assuming.
