I am continually shocked that CIOs, data center design teams, infrastructure managers, and data center operators ignore the lack of cooling control systems in data centers. Data centers are mission critical facilities that require 100% uptime. Their cooling infrastructure requires continuous vigilant surveillance.
The cooling infrastructure for buildings, which are not mission critical facilities and can afford an hour or two of downtime, has been developed to monitor, control, and alarm when conditions become sub-optimal. Compared to the sophistication of building cooling infrastructure, data center cooling control systems are practically non-existent. In other words, if building cooling control systems just graduated with a PhD, data center cooling control systems would be stuffing envelopes as a college intern.
I had a chance to chat with Layla Monajemi, an energy engineer working for EMCOR Energy Services. Layla specializes in mission critical facilities such as data centers but also has experience with commercial buildings, labs, and campus environments. Layla was the first female to receive the Data Center Certified Energy Practitioner (DC-CEP) recognition from the Department of Energy.
Dan: In terms of energy efficiency, what are the three most common mistakes that you see in data centers?
Layla: The most obvious mistake that I see is cooling the hot aisle. More often than you would think, operators feel the need to place perforated tiles in the hot aisles because to them, hot is bad. Hot is bad in the cold aisle, hot is ok in the hot aisle.
How many photos do you think there are on Facebook? 500 million? 1 billion? 7 billion – one for each person on the planet? Current predictions have the number around 100 billion. That is 200 million uploads per day. Where do you think 100 billion photos are stored? What about all those Gmails, Tweets, or blog posts? They reside on the cloud, of course. Putting it on the cloud is the cool thing to do these days. Our photos, emails, bank statements, car payments, books, movies, video games, and our favorite YouTube videos are all on the cloud. All this good stuff isn’t stuffed into our iPhones…so where is it?
