Cooling
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 [...]
Continue ReadingIf you have been following the storage business for a while, you will have noticed a few changes:
Introduction of Flash Memory components as Solid State Disks
Serial ATA (SATA) disks becoming popular and growing in capacity (2TB soon)
There are lots of other disk technologies around like Fibre Channel and SAS but SSD and SATA are getting [...]
Continue ReadingBack in 2008, Steve O’Donnell wrote an article here on The Hot Aisle explaining one of the challenges he set his team during his time at BT, the difficult task of getting Asset Management right.
To summarise, Steve kicked off an audit of the whole estate, and where owners couldn’t be found for kit on the floor, [...]
For years I have been a prolific photographer of Data Centres all over the world. I have hundreds of images, some brilliant, some out of focus and under-exposed, (I am a data centre guy, not a professional photographer). I thought that I might publish some of the better ones with a bit of narrative about [...]
Continue ReadingLast week I met with my friend Steve Sole of Nubis who wanted to tell me about the work they have been doing in data centers around improving energy efficiency. Nubis make demountable Aisle Containment systems – they don’t care if it is Hot or Cold Aisle – the objective is to stop the air [...]
Continue ReadingRecently The Hot Aisle conducted an online survey asking the question -
“How do you currently choose where to place equipment in your data centre?”
As usual we got a very large response to the survey with 5,580 respondants.
The results are in and it shows quite clearly that equipment placement is (to say the least) unsophisticated. A [...]
Continue Reading…that cooling data centres using refrigeration is madder than a box of frogs.
Maybe he could have suggested, fresh air cooling or the new Iceotope liquid cooling solution and kept his job whilst avoiding the toxic blob.
Iceotope Unveils First Modular Liquid-Immersion Cooled Blade Server
Supercomputing 2009, Portland Oregon; 17th November 2009: Iceotope (www.iceotope.com) today launched its new liquid-cooled server technology. The system is believed to be the first to use modular “liquid immersion” of the server components and is able to reduce data centre cooling costs by 93%, saving hundreds of thousands [...]
I recently chaired a very interesting panel debate and discussion Hosted By BLADE Network Technologies in London.
The panel was made up of:
Harkeeret (Harqs) Singh, Global Head Data Centre Energy Optimisation, Thomson Reuters
Finlay MacLeod, VP IT Infrastructure, EMEA, First Data Corp
Charles Ferland, VP of EMEA, BLADE Network Technologies
Brian Peterson, VP International Operations, Emulex
Tikiri Wanduragala, EMEA xSeries [...]
Next week, Iceotope will announce that it has developed, patented and manufactured an extreme IT equipment cooling solution. The solution tackles the problems of cooling servers in data centres all the way from the actual source of the heat – at the processor and memory component level – to its final destination – outside air by [...]

From the coal or oil delivered to the power station all the way through to the energy that drives our business applications the efficiency story is woeful.
I met with Dr. Bruno Michel who is IBM’s, Zurich based, advanced thermal packaging manager yesterday. We spoke about IBM’s view of cooling technology in the 5 to 10 year horizon and what I heard was interesting and credible. IBM have been working with liquid cooling for some time, in the HydroCube, in the new [...]
Continue ReadingI 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 [...]
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 air [...]
My friend Dan Gatti who runs worldwide marketing at Verari sent me this picture showing the inside of a FOREST Data Center Scale computer rigged out with 26 Petabytes of disk storage. Verari are market leaders in Data Center Scale compute platforms and have shipped significantly more of these storage and compute units than other vendors [...]
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 [...]
Continue ReadingI am old enough to remember the 1960’s when IBM Mainframes used de-ionized water delivered by micro-bore pipes to cool the CPUs. (In fact I remember a spillage during a mainframe move that resulted in every single auto spares shop in south east England being raided for deionized water).
In a recent statement IBM claim that direct [...]
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 falls. [...]
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 to deploy [...]
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 [...]
Continue ReadingLast 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 sites that [...]
Continue ReadingThe 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 air and [...]
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 [...]
Continue ReadingI took these photographs a bit over two years ago at the BT Reuters Data Center in Nutley New Jersey. They show a large CRAC Unit in the process of being installed. Note the copper piping, solder joints, open floor void and general mess that is involved in installation and commissioning. This is not something [...]

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 to maximize the availability [...]
