A few remarks on parts of the article:
EMC's FAST (Fully-Automated Storage Tiering] is not new in the industry, Compellent (now owned by Dell) did it already with Automated Tiered Storage since 2004
Also what makes me sad, is there is still the focus on FC while there are other technologies available (10 GbE, FCoE, etc.) that can do the same but for a lower price.
Its a interesting article, lets see what the competitors come up with :)
