3. Hyper-V can’t run that many VMs per box (I don’t get the density) Hyper-V can’t perform under load I can’t/won’t run my business critical applications like SQL, SharePoint and Exchange on Hyper-V Try Hyper-V R2, it makes a big difference. Don’t compare against R1 of Hyper-V Windows Server 2008 R2 has incredible performance Hyper-V R2 is a phenomenal platform for your Microsoft business critical apps and your apps from other ISVs as well

4. iSCSI Performance with Intel® 82599 10G NIC with VMDq, Intel® Xeon 5580 Platform, Windows Server 2008 R2 and R2 Hyper V Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Microsoft Intel products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing. Read/Write IOPs and Throughput Test

7. * Used pre-release software (ESX Build 148592) and the iSCSI initiator in the VM (not pass-through). For Hyper-V, they used pass-through drives for data. **HP would likely see similar results when replacing their own older systems with new HP machines ***Consolidated and Virtualization Hardware platforms were the same in both tests Given the minor differences, Hyper-V is an extremely viable alternative to ESX, capable of competitive levels of VM density, even for customers who already have sunk costs in ESX licenses. For customers embarking on new virtualization deployments, Hyper-V is VERY competitive!
