And my point is that Windows has no global option to turn off its caching and do directio, so you must have misinterpreted the questions in the other posts. ATTO does directio at the application level by explicitly making direct io calls instead of buffered io calls. You can't do it system wide or on a disk basis. An application has to choose not to do buffered io.
So if you disagree, explain to me how you would turn on/off the Windows caching.
