I am investigating the possibility of linking Visio drawings / objects to the external data contained in DFM for the sake of simplicity. Per the Visio documentation linking to an external DB relationship is possible, but I can't find anything yet from the NetApp OnCommand/ DFM resources which provides any detail about the middleware / ODBC links into the MySQL DB. We updated to OC v5.2 recently and are also looking into migrating towards using Balance. Any pointers / suggestions on the methods for connecting to the DFM DB would be helpful.
I have Balance running but haven't got DFM setup yet. Balance is nice for sorting issues and viewing over all performance but I've found its not great for lun/volume level stats without hooking the host into Balance too.
It's also quite a black box. I would personally push forwards with linking into DFM as my impression is that it is far more flexible and featured.
