In our last article, I showed that the current power management does not seem to work well with the Windows Scheduler. We got tons of interesting suggestions and superb feedback. Also several excellent academic papers from two universities in Germany which confirm our findings and offer a lot of new insights. More about that later.The thing that is really...

As promised for a long time, we've been working on pitting Xen and OpenVZ against eachother in a little "battle of the free virtualization solutions". (If you can't quite recall what this OpenVZ business is all about, we suggest you go read our article on container-based virtualization)
Though development of our vApus FOS benchmark suite is moving...

I've been using Dish Network for quite a few years now. Recently, I went through a forced upgrade to their latest ViP 722 high definition DVR. (I say "forced" because the older ViP 622 I had died, and Dish no longer supported the older unit. I didn't have to extend my contract, though.)
I haven't paid a great deal of attention to how rapidly IPTV services...

Cloud Computing was probably the most popular buzzword of 2009. There was a lot of hype, but basically, cloud computing is about using the large datacenters of the Internet to your advantage. Either by copying the methods they use to be very scalable and available and applying them in your own datacenter (what VMware is partly trying to do with their...

Agner Fog, a Danish expert in software optimization is making a plea for an open and standarized procedure for x86 instruction set extensions. Af first sight, this may seem a discussion that does not concern most of us. After all, the poor souls that have to program the insanely complex x86 compilers will take care of the complete chaos called "the x86 ISA",...

If you've been keeping up with our articles for a while, you might have picked up on vApus Mark I: the virtualized stress test we created for internal use at the Sizing Servers testlab.
As detailed in Johan's article, this bench consists of 3 separate applications, all of which we are very familiar with due to extensive optimization and stress testing...

First of all, we were pretty excited to see so many comments and votes (5000!) on our last IT poll. It is good to see that professional IT is so much alive at Anandtech.com. So yes, we should have updated this blog quicker, to keep the momentum going. The reason why this update comes rather late is -once again - that we are working on the much delayed hypervisor...

If you read our last article, it is clear that when your applications are virtualized, you have a lot more options to choose from in order to build your server infrastructure . Let us know how you would build up your "dynamic datacenter" and why!

Take two Nehalem dies, turn them 90 degrees, add a lot of system interface logic and 8 MB extra of L3-cache and you get - very oversimplified - the impressive Nehalem EX, alias "Beckton". The new Xeon MP is an impressive monster, just like it's predecessor Dunnington. Dunnington consisted of 1.9 Billion transistors, the Xeon MP based on the "Nehalem"...

We promised you a new datapoint, a new independent virtualization benchmark in "a few days". Those "few days" have become a week in good "IT at Anandtech" tradition. :-) But this wednesday, unless Murphy strikes us hard, the article will be online. It will offer a refreshing look at the virtualization performance, the result of months of work. Liz...

In our last article about server CPUs, I wrote:
"the challenge for AMD and Intel is to convince the rest of the market - that is 95% or so - that the new platforms provide a compelling ROI (Return On Investment). The most productive or intensively used servers in general get replaced every 3 to 5 years. Based on Intel's own inquiries,...
