We deployed a MD3200i with two MD1200 shelves in a remote data center recently (mid-2011). It's supporting a VMWare ESX 3-server cluster with 96 physical cores and 768GB of RAM, and also stores the LUNs for a SQL database cluster. 600GB 15K rpm disks. The ESX environment is nowhere near capacity, but we have several virtualized database servers on it that are running fine so far. No trouble with it, would recommend it as a cost-effective VMWare platform. Hard to beat the cost and performance. For the size of deployment we have I'll give it 5 stars due to the affordability and performance.
