Interesting article in NetworkWorld talking about market shares gains of alternative hypervisors to VMware.

According to the article and IDC, Hyper-V grew last year at 62%. Also in the article, Gartner states Hyper-V market share will be 27% of the market, up from 11% two years.
Those are some significant changes.
This data makes sense especially in light of the technical advances in Hyper-V over the past few years. Our Senior Systems Engineer, Jonathan Klick, created a compelling chart showing some interesting characteristics between vSphere 5 and Hyper-V 3:

You can read his entire blog post here.
The market share numbers are interesting in that they reflect a diversification of hypervisors. What they don't reflect is diversification of hypervisors within an organization. We are clearly starting to run into these organizations, and believe they are growing. Application affinity, open source dedication, cost, tiering strategies, acquisitions, all drive organizations to adopt multiple hypervisor technologies. So whether you are operating as a monolithic hypervisor company, or you run multiple hypervisors, or are using one of the emerging vendors, it looks as though you are in good company. Greater hypervisor diversity in the market is a good thing and will continue to accelerate.

It's nice to have competition in the virtual arena but the chart is meaningless. vSphere 5.0 is here now, people can enjoy all the nice features mentioned. Hyper-V 3.0 is a long way from being released. Probably end 2012 but knowing MS this is anything but sure.
If you want a real comparison between vSphere, Hyper-V and XenServer with features available now, check out http://www.vmguru.nl/wordpress/2011/11/updated-enterprise-hypervisor-comparison/

I often see this comparison table with exactly the same wrong info on Hyper-V v3 Max VM Disk. The maximum size currently is 16TB which is still open for change because we are only looking at the pre-beta. For Erik: 2012 will show considerable growth for the Microsoft Private Cloud ecosystem based on Hyper-V & System Center which will reach far beyond the question which only the hypervisor is capable of. VMware still has some work to do to compete on the application and management level. Merry Christmas!

Thank you for the comparison. As shared by Hans, the max VHDx size is 16TB. Would you have a comparison or can extend the comparison to cover the following too.
Enhanced CPU support, eg NUMA in the VM, etc
Maximum running VMs per host, eg 1024 for Hyper-V v3
Number of vNICs
Storage and storage HA capabilities
Supported storage types, eg NAS, NFS, iSCSI, FC etc
Green IT type capabilities, eg Core Parking
Thanks.
