Why Current Network Security Fails

Why is it that advances in data center technology have so far failed to produce decent digital security for enterprises? Even with the newest firewalls, encryption schemes and what more, breaches are an almost daily occurence.



The answer is actually quite simple, as we can read in this article in Processor Magazine. The whole model that has… Continue

Point of discussion: should less be more?

Quick post today. I came across a blogpost by Doug Mohney at Green Data Center News today. He took aim at a new solution by Alcatel Lucent.



Basically, it's very simple: it concerns a network of piping that transports heat from the racks to the heat sink. Nothing special really. The main problem is that is could well be less green as advertised. Mohney could very well be right about that: installing it might be very energy intensive.



My question to the community is: is he… Continue

Another Small Win for Standards

We all know the need for standards within the data center sphere. But with standards, you also need enforcement and incentives for companies to apply them. Unfortunately, that advances slowly.



Sometimes however, a small but significant step is taken. Take the recent news that SGI is redesigning their ICE Cube container data centers to fit standard… Continue

Hurray! The Crisis is at an End! (or is it?)

At least, that is if I can believe Gartner, who just send me this bit of news:



"Worldwide server shipments grew 23 per cent year over year in the first quarter of 2010, while revenue increased 6 per cent, according to Gartner, Inc."



Hurray! That means the crisis (at least in IT) is fading. It is about time, because server shipments were hitting rock bottom the last year.



However, that is not the whole story:



""We've seen a return to growth on a worldwide… Continue

A New Metric to Keep Uptime High

This is a bit of 'breaking news' I got from Techtarget today: The Uptime Institute has drawn up a new metric to measure the ability of a data center to keep running without interruption. Called the Operational Sustainability benchmark, it is to published on 1 July.



We know the Uptime Institute for their… Continue

The Ever Lasting IT-Facilities-Management Conflict

In the world of data centers, the IT department, the facilities department and general management seem to be constantly at odds with one another. Each one has different goals, and different ways of doing things. This article on data center journal is the most recent one exploring this theme. The article links back to many… Continue

The Future of the Data Center is not Green, but another Colour

Would this been posted to Data Center Knowledge about one-and-a-half month ago, I would have ignored it. But as it is not 1 April, this is way to good to pass up: HP have done a study about utilising cow manure as a source for power. The paper can be found here, and here is a video where Chandrakant Patel from HP… Continue

The Westmere and GPU's make a Push

This year was bound to be a year of server refreshes, and in short succession HP and IBM have done just that. Respectively the HP ProLiant ranges and IBM System x have had an overhaul to take their servers forward another two years or so.



In both cases, the most important upgrade is the processor. The start of this year saw the release of the new Westmere architecture by Intel, and the big three can't afford to let the processor slip by. Its six cores (although four cores are still an… Continue

Multi-tenancy explained

Sreedhar Kajeepeta, CTO of Computer Sciences Corp., has written an column for Computerworld explaining the concept of multi-tenancy.



That concept really isn't all that much. It just constitutes the core of the whole cloud computing model.



While I can reproduce the article briefly in my own words, I don't think that's necessary. It is a quick read, comprehensible and it offers some examples. You can read it… Continue
