In reply to Jeff Burke.

Thank you for your perspective. It is always nice to see comments from business leaders and CEO’s like yourself. The message is not an argument against technology like OptiCool's rack door heat exchanger. The point is - available space, power and cooling define the amount of compute, storage and networking resources that can be deployed per rack. Simply packaging more servers into a smaller form factor does not automatically imply users can deploy more servers per rack. There is no such thing as a free lunch. An overwhelming majority of data centers in the world cannot support a rack density above 12 kW. To support high density racks, additional mechanical and electrical infrastructure equipment is required. This additional infrastructure adds cost and complexity. There are specific use cases that may justify the additional expense and added complexity. However, this is not the case for the vast majority of data center deployments. The bottom-line, customers must be aware that deploying servers packaged in a smaller form factor does not mean they can deploy more servers per rack.
