Current Ethernet Not Enough?

At the recent Ethernet Technology Summit, there was grousing going on about the need for more power-conservative switches, for more manageable switches, but most of all for faster Ethernet.

Facebook, for one, spoke of having 40Gbits coming out of each rack in the data center, and related how its 10Gb Ethernet fabric is not enough and won’t scale. There are new standards (100Gb Ethernet and Terabit Ethernet) but they are not yet finalized. Analysts suggest that there is a pent-up demand for 100Gb Ethernet, and the conference bore that out.

Supposedly, there is supp

Largest Data Center Consolidation Ever…

The United States federal government recently announced that there was to be a reduction in the number of data center facilities. The United States CIO Vivek Kundra sent a memo to agencies announcing the move and required preparations for it.

In 1999, there were 432 facilities; eleven years later, the number has nearly tripled to more than 1,100.

Reasons given for the massive reduction include costs and energy efficiency. With the changes in the federal government that happen every four years (otherwise known as “electing a new president”), it should not be a surprise that the consolidation is to happen by 2012.

With the economy as it is currently, any massive change like this will affect many sectors. Data center providers that have inefficient facilities will find themselves losing a major customer if federal agencies leave for other providers.

This shift to more efficient data centers, on the other hand, can spur the building of new data centers: this will affect the building trades in a positive way, and quite likely shift the related data center providers towards a more positive outlook.

Intel is also going through a data center consolidation; they’ve an entire web site dedicated to the process which has valuable information.

A Book Review: “Green IT”

The book Green IT: Reduce Your Information System’s Environmental Impact While Adding to the Bottom Line by Velte, Velte, and Elsenpeter is extremely interesting. Unlike some other books that might go in this direction, this is not a book of theory, nor of political change, nor of persuasion. This is a book for IT staff about how to create a “green” data center and more.

Because of the nature of IT, going “green” can mostly be summed up in one word: electricity. A vast amount of what makes an IT department “green” consists of using less electricity wherever possible. This includes such areas as the corporate data center, the corporate desktops, and much more.

However, the book also gives significant attention to the other big environmental impact of computing: paper. There are a lot of ways to reduce paper use, and this book seems to cover all of them.

The book is in five parts: part I explains why to implement conservation in IT; part II talks about consumption; part III discusses what we as IT users can do individually to help the environment; part IV covers several corporate case studies; and part V expounds on the process of becoming “green” and how to stay that way.

It would have been nice to see more information about how the authors exemplified their suggestions during the creation of the book. The only hint of any environmentally sound practices is the recycled paper logo on the back cover (100% post-consumer fiber). That leaves more questions: did they use thin clients? Did they work from home? Did they use soy ink? Perhaps lastly, where is the e-book?

There is a web site that is set up for the book, but the current breadth of the site is disappointingly anemic. Some of the best web sites for Green IT would be Dell Earth, Intel, as well as IBM’s Green IT and Energy, the Environment, and IBM web sites.

It was interesting to note that HP’s Eco Solutions web site is “heavy” compared to the others – that is, it requires much more processing power to display, and requires a lot more time to download – which translates into more power consumption to view the web site. In addition, IBM and HP are the #1 and #2 in Computerworld’s list of Top Green-IT Vendors – whereas Dell is #6… HP also topped Newsweek’s 2009 list of Greenest Big Companies in America (along with IBM, Intel, and Dell in the top 5).
