I have no experience with data centers and ‘Mission Critical’ HVAC systems, but the topic combines three things I’m interested in: Computers, HVAC, and Systems. When I was just a kid I spent a week at Control Data Corp. in Minneapolis. During one of the hottest weeks of the year, my mentor taught me programing. There was no air conditioning at home but in the equipment rooms it was 68 degrees. You almost had to wear a sweater.
Jump forward forty years, and the equipment rooms are jam packed with servers. The cooling load is larger than the equipment load, and they’re cooling 365 days a year, even when it’s -20 degrees outside. Some brave souls are starting to think twice about how they cool their servers. Companies like Google and Facebook have so much invested in their server farms, that any savings translate into millions of dollars.
Kevin Dickens, P.E. in the April 2014 Engineered Systems looks at opencompute.org and their Open Compute Data Center Mechanical Specifications. Open Compute Project is an open source consortium of data centers and equipment manufacturers and interested partners including Facebook. Dickens muses on were all this experimenting has taken us and where it might lead.
For most of us, change has to be incremental. Our risk model does not allow us to step too far outside of our, our management’s, or our client’s comfort zones. But when we can learn from those on the bleeding edge, we should have the courage to step out onto the leading edge. We do that not by stepping out of our comfort zone but by educating ourselves and expanding it instead.
