DC Power Revisited

By John Peterson | Apr 25, 2019

DC power has been proposed for use since Edison debated with Tesla about which should be used.  Ultimately AC has been used more since it allows transmission over long distances which suited having large, centralized power plants.  But with so many of today’s devices and systems using  we see a resurgence of DC power AC […]

Artificial Intelligence in Data Centers

By John Peterson | Mar 11, 2019

First, how do we define AI?  In commercial buildings AI is often thought of as applying analytic engines on gathered information then use those models, algorithms, and rules to make better decisions on how the systems are operated.  Most of us aren’t programmers and we use the term AI with the intention of adding sophistication […]

Cryptocurrency and the Data Center

By John Peterson | Jan 06, 2019

As blockchain and cryptomining were starting, people were attempting to do the same in their garages and other ad-hoc locations with little thought to scaling or efficiency.  But once those power costs started to add up, it was clear that they needed to relocate even if they did have to rent in a new space […]

Balancing Density & Size

By John Peterson | Dec 15, 2018

Data centers have become larger, more dense, and taller over the last decade. This growth is fueled by the expansion of data; of course, as every industry realizes how data can be used to improve their processes and every company collects and processes more information than ever before. But the deciding points of whether to […]

Densification: Power & Cooling

By John Peterson | Nov 09, 2018

Another option that continues to grow year-over-year is not going up or out at all, but solving the need for more compute by increasing IT density. The computing power density has risen from 5 kW per rack a decade ago to an average closer to 15 kW per rack for today’s new data centers. The […]

Land: A Shrinking Resource?

By John Peterson | Sep 04, 2018

The amount of land available to us is finite and we need to carefully manage how the land is deployed for the many things around us. This has led to the development of land use plans for cities across the U.S., and with the explosion of data this now includes adjustments for more land devoted […]

Waste Heat Reuse

By John Peterson | Aug 25, 2018

Servers have a wide range of energy use, depending on traditional use or specialized for applications, with a typical server using around 350 watts of power.  This average server also produces about 1,200 BTUs of heat every hour and for years many of us have aimed at capturing and reusing this heat.  With potentially 50 servers or more in a rack, this […]
