Virtualization drag



This article walks through several scenarios and yet another attempt to warn users. Why they used the title "VMware: the..." is something I can't comprehend. In many ways this article is repetetive.

Oddly enough, then, when we recently asked readers which tech buzzword they most despise, virtualization came in a strong second, just behind SOA. One in four respondents threatened bodily harm to the next salesperson who mentioned it, and 20 percent said they didn't realize expected benefits.

Still, virtualization is here to stay, and that's a good thing despite its apparent image problem. Whether you use Microsoft Virtual Server, VMware, Xen or another package, virtualization delivers a raft of benefits, from better use of physical assets to improved management of applications to the ability to divvy up resources across machines in a way that the sum of a virtual assigned resource--such as memory--exceeds actual physical memory. Using virtual machines may reduce physical server count by moving older applications off older hardware to newer systems that are less likely to experience hardware failure or, in the event of failure, have better parts availability. We found ways to boost the payoff from virtualization technologies, and our testing highlights which areas will suffer least from performance drags.


Since VMware's ESX is under spotlight everytime someone wants to talk about virtualization. A lot of people are indeed getting a bit tired with the "overuse" of the term Virtualization.

You ought to talk to the clients who have used VMware VI3 successfully in their environments. Go to VMworld this year and see and hear how they have squeezed all the servers without compromising on performance. Read the rest of the article here.
