Yesterday Chris Leahy (my Technical Facilities Manager) and I were agonising over why we had low plenum pressure in our Data Center and why we were seeing symptoms of hot air trapped in the roof void. We looked at all the normal stuff: Leaks in the plenum space Badly sealed floor Cable access holes improperly […]

There are a lot of them around, Data Centres. A few of them are designed and operated very well and deliver great Power Usage Efficiency. Some could do a bit better, perhaps an airside economiser or two, or some hot or cold aisle containment, or maybe some DC power. Some are just a nightmare and […]

Data Centre design is an evolutionary process and we can see the first signs of significant change in the latest sites. Co-generation, liquid cooling, cloud computing, high density are all likely to feature in the 2020 Data Centre. How are you placed with your existing Data Centre investments to take advantage of these changes? Will […]

Here is a video from my friend Professor Masood Amin @Massoud_Amin who is the world authority on Smart Grid. If we want to save the planet from global warming, prevent terrorists shutting down our economy and prevent catastrophic failure of our power distribution systems. This is the template of what we need to do and […]

I recently had a conversation with Mark Anzani, IBM’s CTO for System z, the mainframe platform. Regular readers will know that cooling technology is a favourite subject here on the hot aisle and I was keen to get an answer to how IBM plan to cool their next range of machines, the z11 series. IBM […]

At ESG we’ve teamed up with Dell, Microsoft, Symantec, VMware, and Intel on the Virtualization Tour show that’s all over North America (for now)! From September 29th pretty much every day through the end of October, we’ll be in a US city! The content is excellent – based on some killer ESG research and analysis […]

Sometimes the IT business and technology in general gets it right by looking back into history for sensible solutions to intractable problems. By combining modern engineering with old designs we get something extremely smart. To provide stay up power whilst our engines get up to speed we can now use flywheel technology to store kinetic […]

Here is a photograph of my ESG colleague Taya Wyss and Cesar Orosco from NetApp in Sunnyvale standing in a smart cold aisle containment system. This is an aftermarket fitting in a relatively old data centre but nevertheless a useful improvement to cooling efficiency. The photograph shows cabinets facing front to front so that the […]

I am on the West Coast of the US this week visiting with NetApp in Sunnyvale again. On this trip I had the opportunity to visit a couple of NetApp’s internal data centers (B11 and the impressive B2 sites) with Cesar Orosco, NetApp on NetApp IT Architect. Cesar is charged with using NetApp technology in […]

I recently met with Mark Shirman, CEO and Founder of Glasshouse Technologies and had the opportunity to get another exclusive Hot Aisle interview. Mark is uniquely placed to comment on the recent changes in the Data Center and Storage markets with particular emphasis on Green issues. For many years Glasshouse has been the leading independent […]

      I picked up an interesting article on the Executive Business Lifestyle website. (You have no idea the lengths that The Hot Aisle goes to in order to deliver interesting content!) Scouring through rubbish tips for reusable items and materials is nothing new. We see the practice on TV regularly, usually accompanied by […]

      Our atmosphere (the air around us) is made up of gasses consisting of nitrogen (78%), oxygen (21%), carbon dioxide (0.3%) and water in the form of vapor (humidity). The amount of water in the atmosphere is measured as a Relative Humidity (RH) Data Center air should contain the proper amount of water vapor […]

I wrote about Elean Park Data Center some time ago on The Hot Aisle where we looked at the use of absorption chillers that use the waste heat from a biomass power station and gas generation plant on site to drive them. Howard Phelby of 5 nines kindly sent me the attached diagram that shows […]

I was reading an article about the recent Silicon Valley Leadership Group (SVLG) Data Center Energy Summit, in San Francisco, engineers and data center pros gathered to study 11 case studies on energy efficiency. The data center studies varied, but one green data center tactic stood out: hot-aisle/cold-aisle containment. The Hot Aisle readers know that data center […]

  Dry coolers are used in many air cooled refrigeration systems. In case of low outdoor temperatures, outdoor air can be applied for cooling applications. In dry coolers, large fans create a forced airflow along air-to-water heat exchangers. Subsequently, the water circuit can be used for cooling of data centers, office buildings and industrial processes.  Dry coolers play an important […]

I had two great questions from Hot Aisle readers following the latest article on Cold Aisle containment. Dan asked about the impact on fire suppression and Mark asked about where we got the transparent curtains. Lets start with the impact on fire systems of having either hot or cold aisle containment. The safety of personel […]
