While both Microsoft and VMware are working hard to convince existing and potential customers on why they should buy their products, it’s hard to find non-biased comparisons nowadays comparing the features of the current VMware hypervisor vSphere 5 and the just released Hyper-V 3.0 part of Windows Server 2012.
Marcel van den Berg has written a series of blog post making that comparison. And we recommend people who want to make the comparison to read these series of articles in order to get an idea of what each product can do.
You can read the articles here:
Please note: due to the fact that VMware most probably will get rid of the vRAM aka vTax licensing, the article comparing the costs could soon be outdated. Also keep in mind that VMware will most probably announce the release of vSphere 5.1 containing new features at VMworld later this month.
In the near future, virtualization.info will post more non-biased articles comparing the different features of the main hypervisors and the management systems surrounding them.
