I have quarter rack configuration.
Just wanted to check whether i can install any additional Hardware components or software components on either Exadata storage servers (cells) or on exadata db machines ?
I am just done with my initial exadata installation.
On DB Side : NO HW installation allowed (except switches), but SW can be installed ==> to be more clear on this only certified software's can be installed on exadata database server else you may loose the warranty.
On Cell side : Neither HW nor SW can be installed ? ==> Correct.
