From what I have found via google, what I suspect you are looking for does not exist in a ZenPack currently. I have found a MIB set that your EMC device will likely use, but you will have to make a local template and manually add in the snmp OID's that you want to graph.

In particular, this one seems like a good candidate: 1.3.6.1.4.1.1139.1.1.1.20
I believe this will be against your EMC device directly via a managment IP address, and not your server that is consuming the storage. Otherwise you can write a dirty parser that plays with the XML API responses and tease the data out that way. (painfull though, just did that for a P2000 and it was horrible in bash)
