If you have a lot of data stored on SANs, you might want to take a look at the latest offering from Datacore Software’s SAN Symphony. I have been testing various versions of this product for more than a decade, and my latest video screencast review can be found here. They make it easier to automatically move data between storage tiers (such as solid state hard drives and cloud repositories) and enable continuous data protection with just a single mouse click. There is also this nifty heat map as you see above that shows your most-active storage tiers.
