Around this time, analysts at ESG pull together a ten point list of predictions for the coming year. One of my areas of coverage and of expertise is in the Data Center around power, cooling, reliability and economics. So what’s different this year from prior years?
Strengthening fundamental drivers will likely make 2010 materially different from [...]
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 [...]

Be aware that compact fluorescents can take one to three minutes to reach full brightness. This is not a defect.
The place where people are most likely to use compact fluorescents, closets, may be a poor choice. Experts at Energy Star [...]
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 [...]

Often the simplest ideas are the best. People wandering around the data center with mucky shoes can spread dust and other contaminants that can be sucked into the airflow and end up causing problems. These adhesive floor mats located at all entry points into the data center are designed to capture the general filth that [...]
I 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 [...]
Continue ReadingI 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 at [...]
Zinc whiskers, although a catastrophic problem, are not new (they were discovered in 1948 by Bell Labs). They grow on many zinc coated components and structures commonly used in Data Centers. Zinc coating is used to slow the rusting of steel components. There are two types of zinc coating, Hot Dipped Galvanized (HDG) or electroplated. Only one [...]
Continue ReadingYou might think that your data center is under the spotlight, constantly monitored, secure and well designed but what if I told you that typically the second most common cause of catastrophic failures (after electrical) in your Data Center are water leaks?
Water can come from three main sources:
Leaks inside the Data Center from refrigeration equipment [...]

Fresh air cooled data centres simply draw fresh air from outside (via filters) and pump it under the plenum floor rather than the refrigerated and recycled air that is used in 20th Century Data Centres (see picture above). This approach can reduce the energy required to cool a site by 80% [...]
Continue ReadingHow did we get to the modern data centre design? Why do most data centres look the same? Why are they so inefficient in how they consume electrical power? Why do they typically have a raised plenum floor and air handling units that keep air at fixed temperature ranges and humidity levels?
I guess the first [...]
