#100 – Optimising Unstructured Data with Krishna Subramanian

Chris EvansData Management, Guest Speakers

This week, Martin and Chris talk to Krishna Subramanian, President and COO at Komprise.  We mentioned the Komprise technology back on episode #75 (It’s ILM All Over Again) as part of a discussion on managing the movement of files to and from archive storage.  Krishna joins this discussion to fill in some background on the challenges of managing unstructured data, including how to implement solutions with as little lock-in as possible.

Why do we need to manage data in the first place?  With around 75% of all data having no access in over 12 months, there’s clearly a cost saving for primary storage.  This extends further into eliminating backup copy duplication.  Of course, efficiencies can also be gained in performance as well as converting capital costs to operational ones.
