Following on my previous post, today I focus on automated meter infrastructure (AMI) and field area network (FAN). Local area network (LAN) and wide area network (WAN) are well-known terms and do not need explanation. There are a few XANs to indicate the scope of the area covered. For example, a met...

Although I have not abandoned the green IT/data center field, I have also started following smart grid. Smart grid includes the three areas of power, IT, and communications. In this post, I’ll briefly touch on how ICT is used in smart grid.
The power system consists of generation, transmiss...

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...

We’ve talked quite a bit about PCI DSS compliance here. Generally, we’ve looked at what is going wrong, what can go wrong and from there, what organisations should be considering to do it better. Looking at it from a slightly different perspective here but not wholly new either - we̵...

It is often said that smart grid is the power grid superimposed on information and communications technology (ICT). To support smart grid, it is imperative that communications be improved and used for smart grid.
At ConnectivityWeek several weeks ago, a representative from the Federal Communications...

After his presentation, I sat down with Bob Heile, who was chairing one of the IEEE meetings colocated at the recent ConnetivityWeek. I first saw Heile’s name in an article about several wireless protocols, including ZigBee, Wi-Fi, Bluetooth, and UWB. After following that space for a ...

I remember when ZigBee was first officially announced in San Francisco. I was researching wireless mesh networking and attended the TinyOS workshop, which was hosted by Professor David Culler at UC Berkeley. The workshop was in 2005, and the ZigBee meeting was right after that, so it must have been ...

This is a quiz. What is the relationship between C++ and smart grid? One of Fujitsu’s smart grid symposium sessions this week was a keynote speech by Bjarne Stroustrup of Texas A&M University.
Bjarne Stroustrup
He is the creator of the C++ language.
C++ was conceived from C and Simula...

We all know how important it is to develop a Disaster Recovery/Business Conntinuity Plan. If you still don’t have one, consider this : relying on backup data that you have never tested and have no idea how long it would take to restore … is not a plan.

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...
