VMware is going on the attack yet again, slamming Microsoft in a 2,000-word missive on its Virtual Reality blog.
In case you forgot, Virtual Reality is the blog VMware set up specifically to defend itself from criticism by the media, analysts and competitors. The most recent post targets the Microsoft Integrated Virtualization ROI Tool, an online calculator that partners can use to make the business case for Microsoft virtualization.
“Unfortunately we had to give it a failing grade,” writes VMware blogger Tim Stephan.
The post features a pretty in-depth analysis of the assumptions and calculations that Microsoft’s tool makes in “proving” that the upcoming Hyper-V hypervisor is a better value than VMware’s products. (Microsoft’s site doesn’t mention VMware, only a “competitive server virtualization solution.” As Stephan writes, “Gee, I wonder who the competitive solution is?”)
But the best part of the blog are the no-holds-barred shots that Stephan takes at Microsoft throughout. They include:
- “Of course the results were all hypothetical, because Hyper-V is not yet available.”
- “Like most Microsoft version 1.0 products, the initial release of this calculator has numerous errors, contains critical design mistakes, and completely misses its mark. … Maybe we all need to wait for the SP1?”
- “Microsoft’s tool assumes that Hyper-V will run as many VMs as VMware VI3 and deliver the same performance – we can’t wait until Hyper-V ships and prove (sic) this wrong.”
The blog also features this quiz:
Why did MSFT release such a misleading ROI/TCO model?
A) Microsoft did a sloppy and hasty job with the calculator
B) Microsoft is deliberately fudging the facts
C) Both A and B
Microsoft has been promoting its calculator to partners as they prepare to sell Hyper-V and try to chip away at VMware’s server virtualization market lead. I’m in no position to say who’s right and who’s wrong about the tool and its assumptions, but Microsoft partners might want to check out VMware’s stance before they start relying on the calculator too heavily.
