EMC cant do Software
Even if they claim to be one of the largest sw manufacturers. I worked for emc for 7 years as a consultant and i saw navisphere, control center, symmetrix manager (which was already outsourced from cc very early cause the couldnt get cc to control their main storage, the same with navisphere) powerpath, geospan/srdf-ce and so on. They all sucked, were more then heavy to install and support was bloody bad even for internals. Its still the same. Emc cant do usable storage management software. The only stuff that was and is working are their command line tools - not very 2011.... Have a look at Dells storage or others shows you where to buy.
I.e. When upgrading CC in minor or major steps all historical data was lost! This was fact from 5.0 to 6.0 over several version and couldnt be fixed although there was an oracle db below...they needed to drop it. Customers liked this.....
Performance management is historical and ancient - for clariion and vmax. Collect data and get a zip file. Visualize the data in a sucking java gui that slows down even the fattest ram/cpu combo. Customers still complain about this.
I would never buy an emc system again, others just can do muuuch better.
