You answered this post 5 years later? There is no EMC. They are now part of Dell Technologies. As a former DC director, I also tossed EMC a couple of times. Then again, I also tossed IBM, Hitachi and NetAop from my DC.
I also tossed IBM. Never needed to toss HDS or NetApp. Anytime I needed to keep them on their toes I just brought in a few niche players for proof of concepts, let HDS and NetApp's storage engineers see them in my data center and magically I had a whole lot more negotiating strength with them.
