Hi Jean,
Can you please advise how you have proceeded from here.
I understand EMC ViPR SRM would be great in determining the service level categorisation of your storage, which can also be completed with other vendor tools such as OnCommand Insight from NetApp and IBM TPC amongst others.
What you are looking to achieve is the connection from the type of storage protocol it used and what the target type is, i.e. is it a Hypervisor, therefore going to a Datastore or RDM (raw device mapping).
Depending on the size of the environment and different storage vendors within the environment there are different approaches. I am sure your Apptio team you can liaise with will advise you on the best approach forward.
Thanks,
Con Prountzos
