Recovering Cryogenic Refrigeration Energy

Waste heat reclamation in datacenters has long been viewed as hard because the heat released is low grade. What this means is that rather than having a great concentration of heat, it is instead spread out and, in fact, only warm. The more ...

Data Center Cooling Done Differently

Over the last 10 years, there has been considerable innovation in data center cooling. Large operators are now able to operate at Power Usage Efficiency of 1.10 to 1.20. This means that less than 20% of the power delivered to the facility is ...

Solar at Scale: How Big is a Solar Array of 9MW Average Output?

I frequently get asked “why not just put solar panels on data center roofs and run them on that.” The short answer is datacenter roofs are just way too small. In a previous article (I Love Solar But…) I did a quick back of envelope calculation ...

Cumulus Networks: A Sneak Preview of One of My Favorite Startups

Back in 2009, in Datacenter Networks are in my way, I argued that the networking world was stuck in the mainframe business model: everything vertically integrated. In most datacenter networking equipment, the core Application Specific Integrated ...

Microserver Market Heats up: Intel Atom S1200 (Centerton) Announcement

Since 2008, I’ve been excited by, working on, and writing about Microservers. In these early days, some of the workloads I worked with were I/O bound and didn’t really need or use high single-thread performance. Replacing the server class ...

I Love Solar Power But…

I love solar power, but in reflecting carefully on a couple of high profile datacenter deployments of solar power, I’m really developing serious reservations that this is the path to reducing data center environmental impact. I just can’t make ...
