Another Chart for SQL Server database on a single LUN

So, here's another chart for the SQL Server database on one lonely LUN. This chart is more interesting. There's an elbow at about 400 mb/second. Most likely this system, with all of the database files for a heavy-traffic database on a single LUN, is hitting a bandwidth limitation. Could be the front end port limit, could be back end bus limit. Could even be an FCAL limit.
