13. Capability Hyper-V (2012) vSphere Hypervisor vSphere 5.1 Enterprise Plus Dynamic Virtual Machine QueueYesNetQueue 1 IPsec Task OffloadYesNo SR-IOV with Live MigrationYesNo 2 Storage EncryptionYesNo 1 VMware vSphere and the vSphere Hypervisor support VMq only (NetQueue) 2 VMware’s SR-IOV implementation does not support vMotion, HA or Fault Tolerance. DirectPath I/O, whilst not identical to SR-IOV, aims to provide virtual machines with more direct access to hardware devices, with network cards being a good example. Whilst on the surface, this will boost VM networking performance, and reduce the burden on host CPU cycles, in reality, there are a number of caveats in using DirectPath I/O: Very small Hardware Compatibility List No Memory Overcommit No vMotion (unless running certain configurations of Cisco UCS) No Fault Tolerance No Network I/O Control No VM Snapshots (unless running certain configurations of Cisco UCS) No Suspend/Resume (unless running certain configurations of Cisco UCS) No VMsafe/Endpoint Security support SR-IOV also requires the vSphere Distributed Switch, meaning customers have to upgrade to the highest vSphere edition to take advantage of this capability. No such restrictions are imposed when using SR-IOV in Hyper-V, ensuring customers can combine the highest levels of performance with the flexibility they need for an agile infrastructure. vSphere Hypervisor / vSphere 5.x Ent+ Information: http://www.vmware.com/pdf/Perf_Best_Practices_vSphere5.1.pdfhttp://www.vmware.com/pdf/Perf_Best_Practices_vSphere5.1.pdf
