I’ve got a new version of IOsaturation toolkit which you can download here http://karlarao.wordpress.com/scripts-resources/ and it has a cool script called “smartscanloop” that shows you the Smart Scan MB/s per database across the Exadata compute nodes.. it’s a per 2secs sample so that’s a pretty fine grained perf data and near real time text graph. Very useful for doing IORM demos and monitoring what database is currently hogging the IO resources and since it’s presented in a consolidated view you don’t have to go to each Enterprise Manager performance page and have a bunch of browser windows open.
The SECTION 1 is what I usually use to validate the IO numbers on the database side from my Orion (see oriontoolkit here) and Calibrate IO runs. I’ve been using it for quite a while on new RAC/non-RAC installations from client sites.. and I used it heavily on my R&D server while continuously enhancing the toolkit
