My organization currently has three IBM ESS's in place with about 37TB of disk total. For storage and midrange servers, we are almost exclusively an IBM shop. We are evaluating purchasing a large amount of EMC storage, and from everything I can tell, and the customer references we have talked to, they really seem to have their act together.
I know there are numerous people on this forum using EMC storage, and I'd appreciate it if a few of you wouldn't mind giving me your opinion of their products and customer service. Anyone having experience with both vendors would really be helpful. Thank you!
