I am not as comfortable talking ROI at the executive level as I am talking technology with other architects.  Most of my career was trying to solve problems with the tools I was given or in many cases, not given.  When you spend most of your time looking at ‘the other end of the horse,’ you forget to take a step back and look at the big picture.  The bottom line with data protection is that if you continue to use the same old tools and technology, you will not be able to control cost with the continuing data growth.

First I want to welcome you to my first blog. Chris Poelker (our other revered blogger) and I have known each other for many years, even before he followed me to Falconstor. Chris is clearly a technology visionary and big picture guy. I tend to sometimes get mired down in the details. But together we make a great team.

But with a dynamic company like Falconstor, I have enjoyed being able to work the whole life cycle of enterprise projects and still get my hands dirty in the details.
