VMware Outperforms Hyper-V

with 5 comments

All of you have probably heard of the VMware Cost-Per-Application Calculator which was launched a few weeks ago. To prove that VMware has a lower cost per application and a higher virtual machine density, The Taneja Group conducted a series of tests showing VMware’s free ESXi outperforming Microsoft’s Hyper-V in each of these areas. Feel free to read the entire document but for those who are time constrained, here is a summary of their technical findings:

  • Hyper-V is still an immature product with limitations such as memory overcommitment and limited SMP vCPU support for older Windows OSs and Linux. Did you know Hyper-V only supports one Linux flavor with only one virtual processor? Anyone actually running Hyper-V Linux guests in production?
  • Using a DBHammer workload in the guest, you can run up to 100% more VMs on ESXi than on Hyper-V. Actually, there was no technical limitation in creating even more VMs under ESXi, unlike on Hyper-V:

  • On a CPU intensive workload (SPECjbb), ESXi delivers 24% more performance than Hyper-V running on the same hardware. This is mainly due to ESXi leveraging large pages and RVI. Hyper-V does not support these technologies.
  • So what does this all mean to you? Utilizing VMware’s technology, VMware can be 5% to 29% less expensive than Microsoft.

We encourage everyone to try the calculator to see how much they can save with VMware. Here is a quick video demo on how to use the tool, presented by the creator himself, Alberto Farronato. You’ll find his accent quite sexy:

  2. Is that Patrick O’Rourke from Microsoft? Nice to see you comment on our blog! Thanks for stopping by.

  3. Thanks for the link Patrick. We’ll let the user comments to the video speak for themselves: http://tr.im/idLt

  4. Apparently the Microsoft myth busting exercise busted itself – http://www.gabesvirtualworld.com/?p=445

  5. Leveraging RVI, eh? So you can only get acceptable performance on CPUs that have been shipping for the last twenty minutes?
