To virtualize or not to virtualize

With Intel introducing their 45nm Xeon processors, which now have up to 6 cores, servers can now scale up to 16 processor sockets which means 96 cores on a single server.

The exponential growth of the Internet, the accessibility of information and the expected richness (real-time streaming video) means we need more powerful servers to cater for our needs. More servers mean more physical space, and in turn mean more power being used. But with the new processors they pack much more punch but emit less power. Less power also means less heat emission from the processors which require less cooling.

Virtualization is becoming the preferred way for hosting these days and by utilising more powerful servers with more memory and disk space; multiple copies of server operating systems can be installed on a single machine. Packing more virtual servers on a single server enables us to use less physical space and power consumption than we normally would. Tests have shown that for virtualization this type of setup delivers almost a 50% improvement in performance and up to 10% less power consumption.

With Microsoft Server 2008 and true hyper virtualization using processors from Intel (and AMD) true virtualization is now ever more possible. Now it’s not only like likes of Amazon with their EC2 cloud-comuting server architecture but smaller companies too and ISPs that can offer virtualized servers for their own and clients’ use. The Geeks at How-To-Geek have got an aritcle on this very topic explaining hyper-v and virtualization in more detail, read on and find out more and see what true virtualization has to offer and see how it has now become possible to have hyper-v solutions with up to 2TB of physical memory and 64GB of memory per virtual server instance!

  1. i was debating with a work colleague last week that “cache” and “refresh” are not synonyms … no really … he used it “refresh” as an alternative explanation for “cache” … crazy thing is, he wasn’t even using “cache” properly (he thinks it a database) … so i am not even go close to the words “vitualisation” and definitely not “hyper-virtualisation” … i fear for my sanity at work.

  2. @S – I think we’ve all encountered, at some time or other, colleagues or even managers who use certain technology buzz-words as if they really do understand their meaning and usefulness, but in reality don’t have a clue!
