Delta Force IT is a great comprehensive overview of the Data Center for Buyers and Sellers alike. Sean Tario does a thorough job of teaching what you need to know about effectively buying and selling data center space, and associated components. His in-depth industry knowledge shared throughout the course is invaluable. I recommend Delta Force IT training for any professionals in this industry who need or want to know more about the Data Center. Much thanks to the OSI team for a job well done.
