    1. Ahh, now I get it Google uses Clusters the way others use Containers

      Containers work if you want to have a unit of deployment with up to 2,000 servers.  Google used containers early on, but doesn't use them anymore.  Some of the biggest use of Containers is by Microsoft's data center group.  DCD covers Microsoft discussing how containers contain outages.

    2. 2011 data center presentation slides

      I found this presentation just sitting on Utah University's website for a 2011 data center project. Found it interesting that this was 4,000 kW facility with 2,400 kW for critical load for a 1.7 PUE in 2011. Here are pictures of the data center space during construction. I can't recall where I have ever seen Generac generators at a data center site. Generators to provide power in the event of a power outage Brand new facility and their hot/cold aisle containment is not that impressive.  I guess that would explain the 1.7 PUE at full load.  Got to think the PUE is 2.0 during the early phases. Once the racks were installed, airflow zones were created to channel cold air to the racks and contain and vent the hot air from the data center. Power is delivered to each row of racks ...

    3. Did Google Just Patent Hot Aisle Data Centre Cooling?

      Did Google Just Patent Hot Aisle Data Centre Cooling?

      If you feel chilly walking round a data centre, it is probably wasting energy. The data centre has to provide cold air to keep the servers cool, but if it is also cooling the space were people are walking around to an uncomfortably low temperature, then it is wasting energy. Now, it seems Google has a patent on a “hot aisle” containment system which should cut that waste.

    4. Benefits of Data Center Containment

      The data center is fraught with power and cooling challenges. For every 50 kW of power the data center feeds to an aisle, the same facilities typically apply 100-150 kW of cooling to maintain desirable equipment inlet temperatures. Most legacy data centers waste more than 60% of that cooling energy...

    5. Google Adopts Water as key to save Energy in Data Centers, pumps 3.85x better than fans

      Data Center traditionally uses raised floor and in room CRAC units to supply cooling. Google shared a month ago its hot aisle containment with water heat exchange which is the 5th iteration since 2006. Google shared its thinking in evaluating heat removal methods. So should you pump heat or use a fan?  Google modeled a 10MW IT load. The fans use 3.85x more energy than a pump!!! Google found what it had created was so unique they could patent the innovation.

    6. Approaches to Data Center Containment

      Approaches to Data Center Containment

      Legacy data centers employ a hot aisle/cold aisle arrangement of the IT racks. The fronts of the racks face each other and draw cold air into the rack to cool rack mounted IT devices (i.e. servers, switches, etc.). Conversely, the rear sides of the rows of racks face one another, expelling the hot air into the hot aisle. The issue with hot aisle/cold aisle designs is that the air is free to move wherever it will.

    7. Google shares its data center cooling best practice - water and hot aisle containment "hot huts"

      Google shares its data center cooling best practice - water and hot aisle containment "hot huts"
      Google has an end user friendly explanation of its data center cooling. Our emphasis on cooling systems might come as a surprise, until you consider how warm a personal computer can become during use. Data centers, which house thousands of computers, need to stay within a specific operating temperature range. Even though we run our facilities hotter than a typical data center, we need cooling systems - both to prevent server breakdowns and to provide a reasonable working environment for technicians working on the data center floor.After servers, the second largest consumer of power in a data center is the cooling system. We needed a cooling system which minimized our overall energy consumption. For this reason, we designed our own cooling systems from the ground up.  The interior of a hot hut row Google uses hot aisle containment (hot huts) creating a higher delta T  across the water cooling coils ...

    8. How Much Containment Is Enough?

      In an effort to create a more efficient data center infrastructure, IT and facilities administrators began working with hot air containment. Today, this more common practice is used in the industry as a design metric for a well-managed data center. Still, there are some questions around the use of air containment and how it can be best utilized. Since each data center is unique, the use of a containment design will differ based on demand, size, location, and other factors.

      Reducing data center energy waste? We're on it

      Published September 28, 2012 in Climate * Tweet * * Print * Email This week The New York Times began publishing an excellent series of articles examining the high energy demands of data centers -- those rarely-thought-of places that store all the precious information contained on our phones, tablets, and computers. Not only do these facilities use enormous amounts of energy, a lot of it is wasted, the series points out. Part of the problem is t

    10. Airflow Management for an Efficient Data Center

      Since the first computer rooms of the 60’s, airflow has been an important, but often misunderstood component of data center design.  With the low density computing of the past, it didn’t need to perform very efficiently to do its job.  Today however, with high performance servers doing many times the work of their predecessors in a much smaller space, data center airflow needs to keep pace. The first tenet of effective and efficient data center cooling and airflow is to “reduce or eliminate mixi
