After I posted a blog on software energy efficiency recently, I realized from some of the comments from readers that most people did not get it. When I talk about software energy efficiency, most people think I am talking about using software to make other things greener. Yes, software can be used t...

Some time ago, container based data centers got good attention because of its time to market, availability of high power density and focused cooling. As recent as last December, Tier-1 indicated that there is little traction by this technology. Lately, a lot of buzz on this subject are in the media ...

What constitutes a market? Really, take a moment to think about it. Done?
I’ve been asking myself this question for the past several weeks. Seems like I run into a new glassy-eyed IT guy that has heard the words "Fibre Channel over Ethernet" and they’ve been swept off their fee...

If you were as shocked as many of us were to see Ms Clinton speak out about China’s
handling of the Internet, in general, and then the Google debacle too, join the crowd. We described last week in The Informationization Age how the modernization of China’s nation included a plan on...

As I write my daily blog, some readers contact me via several media, such as LinkedIn and email. My blog covers the United States and Japan, but not Europe, for the simple reason that I live in the U.S. and originally came from Japan. When you cover a market of a specific country or region, you need...

I met Jose Iglesias of Symantec when I hosted one of the sessions at the Green Software Unconference in August 2009.I talked to him briefly then and found out that his team was doing a lot in the green software area as well as in the overall sustainability work at Symantec. I finally had a chance to...

Virtualization of computing resources in the data center has yielded significant operational efficiency gains for IT administrators. However, it has also brought several challenges along with it. One of those challenges is the persistent assignment and allocation of appropriate network resources as ...

The quest for efficiency improvement raises questions regarding the optimal air temperature for data centers. The ASHRAE TC-9.9 committee has recently adopted an extension of the recommended thermal envelope for server inlet temperature and humidity. A popular hypothesis suggests that total energy d...

The trend of increasing heat densities in data centers has held consistent with advances in computing technology for many years. As power density increased, it became evident that the degree of difficulty in cooling these higher power demand loads was also increasing. In recent years, traditional co...

Traditional methodologies for monitoring the data center environment are no longer sufficient. With technologies such as blade servers driving up cooling demands and regulations such as Sarbanes-Oxley driving up data security requirements, the physical environment in the data center must be watched ...

High-density servers offer a significant performance per watt benefit. However, depending on the deployment, they can present a significant cooling challenge. Vendors are now designing servers that can demand over 40 kW of cooling per rack. With most data centers designed to cool an average of no mo...

Despite advances in computer technology, power outages continue to be a major cause of PC and server downtime. Protecting computer systems with Uninterruptible Power Supply (UPS) hardware is part of a total solution, but power management software is also necessary to prevent data corruption after ex...
