Do you trust your VMware administrator?

I know the walls are coming down... but there are still many organizational barriers that can exist in IT. How about:
Team work and co-operation? Sure it's an option.... but then an option means its optional.... right?
So when vendors come along with plug-ins and products that dare to connect two worlds... is this a unifying force, or is it anti-matter, or do they just get ignored and not used?
A case in point being the IBM Storage Management Console for VMware vCenter which you can download from here. I have written about this plug-in before, but with the release of version 2.6 (that supports vSphere 5.0), I thought I would try something out. Installing the plug-in potentially offloads a lot of storage management from the storage admin to the VMware admin. But what if the storage admin does not WANT to offload this work?
The answer is to give the VMware admin read-only access.
When you configure your IBM storage device to the plug-in, you supply the plug-in with log-in credentials (so it can log into your IBM storage device and collect the required information). If the user-id supplied only has read-only access to the XIV for instance, the plug-in still works... but not for any operations that change resources. You cannot see the pools on the XIV, but you can still see your volumes and any snapshots that have been created (but annoyingly you cannot see mirrors).
This does have one big advantage. You can clearly match the VMware datatstore name to the XIV volume name. You can also identify which XIV supplied the volume.
I also tested this with Storwize V7000 with a user in the Monitor category and got pretty well the same results. A nice bonus is that I could also see the state of the mirrors as well as the flashcopies. In the example below, all of this information would normally not be visible to the VMware admin, so this is very handy stuff.
Of course I get to also visit one-man bands where the same (exhausted) individual manages the VMware servers, the Operating System Guests, the Network, the Firewall, the Exchange server, the SQL servers and pretty well everything else including getting the elevators and coffee machine fixed. For those people, they need all the help they can get.
