Like other people, I’ve been wondering how Oracle has integrated many of Sun’s technologies and hardware after buying that company. Oracle has just started a nationwide tour to inform us of just that. The first stop was in their neck of the woods, Palo Alto, California. The free semin...

When I started this blog about two years ago, there was a lot of discussion of direct current (DC) power distribution at data centers. It is very easy to see why DC is better than alternative current (AC) power distribution. AC power enters your data center from your utility. It then goes to a se...

I have done consulting work for MySQL as it enters the Japanese market for more than three years. I have not seen Marten Mickos for a few years. I wondered what his next move would be after he left MySQL. I heard he became CEO of Eucalyptus, which is gaining visibility in the crowded cloud compu...

There are a few technologies to make networking more energy efficient. But a more energy efficient Ethernet would have by far the biggest impact because of its ubiquity.
I visited Broadcom to meet with David Berry, senior marketing manager, and Wael William Diab, technical director, office of t...

I reported that container-based data centers are gaining some attention these days. At the recent DatacenterDynamics in San Francisco, Andreas Zoll of i/o Data Centers gave a talk on the modularization of data centers. What is the relationship between modularization and containers? Modularizatio...

After the departure of Andrew Fanara from EPA, a new person is in charge of Energy Star for data centers. She is Una Song.
She gave a talk on EPA’s efforts on Energy Star at the recent DatacenterDynamics in San Francisco.

I wrote about my first idea for a panel discussion in my previous blog, and here’s my second. When we analyze the power consumption ratio among servers, storage equipment, and networking, we find that servers consume far more power than storage and networking equipment combined. That is why th...

When NTT Facilities throws a party, it knows how to do it right. (NTT Facilities is one of many NTT companies, and it specializes in the inside infrastructure of data centers.) Following the conference presentation last week in Tokyo, the other attendees and I were bussed to their research cen...

I have covered many topics as they relate to energy efficiency for data centers. I want to extend that coverage by gathering the experts in each specific topic for a meeting. A panel discussion is a good way to do that.
I have a few ideas that I will use one by one in my blogs as proposals to poten...

I am always on the watch for interesting stories about green IT, cloud computing, and smart grid. When someone pitched me a story about the container-based data center (CDC), I did not pay much attention because, at the time, CDC was dismissed as only for large companies like Microsoft and Google. B...

It has been reported that both the airline and the IT industries are equally responsible for the emission of greenhouse gases—2% each of the total.
The volcanic eruption in Iceland grounded planes in most European airspace for six days. The "Information is Beautiful” website reporte...

I have participated in and run several sessions on the topic of data center energy efficiency here in the U.S. as well as in Japan. I will moderate yet another such panel at SRI at 10:45 a.m. on April 28, less than a week away. This one is a little bit different from the ones I’ve been involve...

In early February, Bloom Energy made quite a splash with the announcement of their fuel cell–based systems. There are several types of fuel cells, each using a different type of electrolyte. Knowing that fuel cells are very hot in Japan, I searched organizations working on the same type of fue...

I will be moderating a panel titled "Data Center Efficiency via IT Optimization, Standards, and Collaboration” at the BrightTalk Efficient Data Center Summit April 21, from 11 a.m. PDT, as you can see here. Energy consumption by U.S. data centers has been increasing, and some are running ...

Although the power usage effectiveness (PUE) metric is not without its problems, it is the de facto standard for measuring energy efficiency in a data center. Japan’s Green IT Promotion Council wants to improve on PUE with its own metric, data center performance per energy (DPPE). The co...
