We are all trying to fix the unfixable in the Data Centre. How do we get more cooling capacity from sites we built a decade ago for low power density applications? One of the biggest problems is that everyone is trying to work against a basic law of physics; hot air rises, and cold air [...]
I was delighted to hear today that my friends, David Wright (CEO) and David Driggers (CTO) at Verari Systems have been recognized for their great work on driving Data Center energy efficiency. For some time it has been apparent that the modular, containerized data center holds huge promise: Ability to deploy new capacity extremely rapidly Ability [...]
I met with David Wright from Verari yesterday and we were talking about high density computing and power particularly about Verari’s data center in a container product. That got us to talking about power distribution problems and the fact that some of the big firms have been buying up sites in old US steel towns [...]
Last quarter, Google posted information about the efficiency of Google data centers and promised to update this information every quarter. They have now kept that promise and published the collected data for the fourth quarter of 2008 to sustainable computing website. Here are the rules: The data center has to have been Google designed (many are colocation [...]
The California Institute of Technology – also known as Caltech — is installing monitors and developing metrics to determine the efficiencies and savings of Hot Aisle Containment enclosures recently installed in one of their data centers. The partitions and dividers were designed and manufactured by Simplex Isolation Systems of Fontana, CA, to isolate hot [...]
Taking social responsibility seriously is a core value at The Hot Aisle so starting today we are launching a new FREE service to advertise IT Jobs with a Environmental component. If you are an employer or agency who is offering a full time or contract position anywhere in the world and that position has a [...]
Interxion, a European operator of carrier-neutral data centres, announced today that the first 1,200 m2 of its new 7,000 m2 Amsterdam data centre—its fifth Amsterdam-area centre—is now operational. 70% of the first phase has been pre-sold to online retail, finance, and ICT customers. Growing customer demand has accelerated the construction of an additional 1,100 m2 [...]
The Pionen White Mountains underground data center has fog, waterfalls, German submarine engines, simulated daylight and …. …… was also designed to withstand a near hit from a Soviet nuclear weapon. It is not a joke, this is a serious and real data center, a newly opened high-security site run by Banhof, one of Sweden’s largest ISPs, [...]
I picked up a really interesting website from KyotoCooling that has a very interesting new approach to low energy cooling systems. The firm takes it’s name from the Kyoto Conference where our governments met and agreed Carbon reduction targets that none of them had any intention of meeting. The Hot Aisle is firmly of the [...]
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 read a very interesting article from fellow blogger Christian Belady, who is Principal Power and Cooling Architect at Microsoft. Christian decided to take the PUE challenge and see if he could build a data center with a PUE of one! That is to have all of the power delivered to computing equipment and none [...]
Chicago Business News reports that Microsoft plans to open another massive data center, in Northlake near Chicago in 2009 that will be central to the software giant’s war with Google Inc. for Internet supremacy. The Data Center, large enough to hold eight football fields, is mooted to cost more than $500 million to build, sources familiar [...]
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 met up with the Mike Klayko the CEO of Brocade last week in the restaurant of the St Regis Hotel in New York (famous for creating the best burgers, bar none, in the city) for an exclusive Hot Aisle interview. Mr Klayko is an industry veteran with decades of experience starting at IBM, [...]
Recently we have been writing a lot about how hot-aisle/cold aisle containment. It is important to be aware this strategy, fire detection and protection requires special attention. A recent article in Search Data Center gives some good advice: Hot-aisle/cold-aisle containment – a variation on the traditional data center best practice of hot-aisle/cold-aisle design – is a way [...]
Today we are going to look at how fire detection systems can be used in Data Centers to prevent catastrophic loss and damage; we will focus on Very Early Smoke Detection Systems, (VESDA – Very Early Smoke Detection Alarm). Without an efficient and safe environment, there is no way to be assured of business continuity. [...]
My friend, the inventor and green innovator, Peter Hopton from VeryPC has a unique view on how to be environmentally responsible whilst deploying PCs into an office environment and he is presenting his ideas at The Carbon Footprint Energy Efficient IT Summit on the 4th and 5th September. Peter says that there are three basic [...]
IT Infrastructure specialist Richardson Eyres recently issued a press release to help drum up some consulting business in the Retail market but make some generally applicable and interesting points worth looking at. Even though most organizations are making energy cuts a top priority for 2008/9, many are not taking green issues seriously enough and are adopting a [...]

RSS (Really Simple Syndication) is a protocol and method for delivering frequently changing web content. Many news-related sites, weblogs (such as The Hot Aisle) and other online publishers syndicate their content as an RSS Feed to subscribers. RSS solves a problem for people who regularly use the web. It allows them to stay informed by retrieving the latest content [...]
Today we are going to look at practical changes that we can all make to our data centres that will improve cooling efficiency, to enable us to install more equipment in the same space or reduce our electricity bills. There are a few basic rules that will help us become more efficient. The first is [...]
The Hot Aisle readership have reported that they have significant constraints on existing data centers with 56% reporting cooling constraints and a further 17% reporting more than one constraint. Significantly only one reader reports space as a constraint which agrees with my hypothesis that there is plenty of Data Center space, just no M&E left.
AVIVA (aka Norwich Union) is set to open its third data centre – Data Centre 3 (DC3) at the Broadlands Business Park near Norwich, UK this September. Although the site uses some modern design principles to minimize energy use, AVIVA have been far too conservative with the design and the opportunity to really go green has been missed. The [...]
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 [...]
