Kyoto Wheeling, or no Dealing?

Quick post today. The Kyoto Wheel has been around since 2007, so it is fair to assess this technology in cooling data centers as a 'mature' concept. Those of you who are already using it know the answer already: Yes, amazingly this somewhat cumbersome brute is actually quite effective in using outside air to cool your data centers.

Techtarget have written a sort of review of the Kyoto Wheel,… Continue

An Interesting Dutch Cooling Concept

(Well, to be honest: Spain did play better. Ok, back to business now, as the World Cup is over and we will have to wait four years)

Sometimes, one can come across a cooling concept which on the one hand seems too simple to be true, while on the other hand it is so simple it borders to elegance.

DatacenterWorks is reporting on the deployment of a data center that is based on a Dutch principle called DataCenterKoeling (translated: data center cooling). Apparently, it is… Continue

Hah! I was Right!

Now, I was at the Imagine Cup that took place in Warsaw this week. I have to say I am knackered.

Earlier, I posted a blog that some of the idea (especially in the embedded sphere) sounded very familiar. I mean, energy management on the level of devices, remote power down etc. etc.

Well, that was just a hunch. Yesterday, I got to talk to one of the team members from the Romanian squad. They had a smart solution that maps all the devices within a home or small office, tracks… Continue

VDI is a Useless Toy

That is not my opinion. It is the opinion of these two gentleman: Don Jones and Greg Shields, of Concentrated Technology.

They argue, in four bulletpoints, that VDI does not offer any value for any business whatsoever. It is a gimmick: It is not cost effective,… Continue

Data Center Economics 101: Cool when it's cheap!

OK, I have been doing a bunch of reading about the highly innovative approaches to energy management being tested in places like Arizona. Phoenix as you can imagine sees temperature extremes like few other places in the country. (I remember stepping off a plane at Sky Harbor Airport in June 1979 and seeing an air temperature of 118-degrees). HEAT is a major topic in…

What Data Centers mean for the World

Right now, I am attending the Imagine Cup competition in Warsaw. For those that don't know, the Imagine Cup is a Microsoft sponsored competition in which teams of students present software projects (based on Microsoft kits, of course) which aim for a better world. Specifically, they have to tackle one of the Millenium Goals of the United Nations. Today the six finalists from each categorie (I attended embedded and software design) got a… Continue

Why has it been so hard to deploy Data Center Monitoring?

Something Wet Leaks from Google

(as you might notice: the further the Dutch football team gets in the World Cup, the shorter my posts. The next match for the Orange Army is on sunday, so no worries there) Do you remember when Google disclosed their server technolody to the world? They did so on 1 April 2009, making everyone think it was some kind of prank. That was also helped by the fact that the Google servers seemed... duct… Continue

The Big Red Button that IT is NOT

This week's issue of the Economist (a newspaper that I hold in high regard for its ability of both analysis and opinionating comments) features a cover story about what it calls 'the war in the fifth domain': Cyberspace.

For some reason, even the most prestigious newspapers make amusing slip ups when it comes to technology. While the Economist article has some passages that will make you chuckle ("Computer bugs bring down military e-mail systems". With 'bugs', they probably mean… Continue

IT is the real James Bond

First of all, let me express my absolute astonishment on the match of today. Holland played so-so in the first half, but what a second half. I am not a chauvinist, but it was a thrilling match and a great result. So good actually, that the Dutch actually proved again that the Twitter data centers are far from reliable enough. I haven't seen so many fail whales in quite some time. What will happen if China starts to play football well???

But I digress. All I wanted to do was point to… Continue
