I usually do not write a blog reacting to real-time news. I leave that to other bloggers, such as Katie Fehrenbacher who covers those pretty well. I usually write a blog when the subject matter comes to cross my path. I cover the story in the intersection of where IT meets energy and express my [...]

Japan Data Center Council Visits Silicon Valley Power for New Ideas to Remedy Power Problems: Part 2
This is a continuation of my account of the Japan Data Center Council (JDCC) visit to Silicon Valley Power. After the disaster in 2011, power remains one of the biggest concerns for Japanese data center operators. Energy mix for power: Power can be generated from multiple sources, such as coal, oil, gas, and renewable energies [...]
Japan Data Center Council Visits Silicon Valley Power for New Ideas to Remedy Power Problems: Part 1
The Japan Data Center Council (JDCC) is a consortium of data center operators, vendors, and users in Japan consisting of 170 member companies. Even before the disaster in March 2011, the JDCC was trying to work with utilities to come up with a suitable pricing structure and other factors for their unique power usage. Data [...]
Canonical/Ubuntu and ARM towards Energy Efficiency
Technical guys are hard to understand unless you are one of them. They tend to be happier if technologies are difficult to understand and only they can understand them. I used to belong to that group and was very proud of it. Most technical details are complex and hard to understand, but that was a [...]
Very Small Footprint Java Development and Execution Environment with ARM Chips
As I reported before, this year’s ARM TechCon’s main theme was low-power computing. The ARM chip consumes less power and realizes low-power computing. Low-power computing is not realized with a chip alone. It needs collaboration from the OS, utilities/middleware software, and applications. And one more thing that is important is a development platform for software. [...]
What Is Cloud ?
I have heard James Urquhart talk several times in the past, but the talk he gave at the recent CloudScale, hosted by Plug and Play Tech, was by far the best and most interesting. He has obviously given this talk a few times elsewhere. CloudScale had a good assortment of presentations and discussions, although each [...]
Low Power Implies Lightweight Software on Processors
This year’s ARM TechCon’s theme was low power. As we reduce the power consumption of computer systems, we can apply them to many areas that we never even considered before. Reducing power involves several elements, including low-power processors and memory. But we tend to overlook software impacts. Software includes both utilities and applications. At the [...]
Japan Data Center Council Pays an Informative Visit to Vantage Data Center
The Japan Data Center Council (JDCC) is a consortium of data center operators and vendors in Japan with 170 members of various sizes. Because of the scarcity of news about Japanese data centers in English, there is seldom enough information about what Japanese operators consider challenges and new developments in their market. I tried for [...]
Low-Power Computing Is a New Trend!
As I cover the intersection of IT and energy, I go to many meetings and conferences. I cover software, hardware, applications, middleware, OS, services, as long as it is related to my coverage area. Recently, I was at ARM TechCon in Santa Clara, CA. ARM has become the dominant standard chip architecture and has been [...]
What’s Next with Data Center Energy Efficiency—Facilities or IT?
What is the next trend in data center energy efficiency? I may be biased because I am more of an ICT guy than a facility guy, when I talk about data centers. Based on my unscientific data, 70%–80% of people who attend a data center conference are facility folks; IT folks are a minority. When [...]
