Unlike VMware, Hyper-V’s SR-IOV support ensures the highest performance without sacrificing key features such as Live Migration

Dynamic Virtual Machine Queue Yes NetQueue1 NetQueue1

IPsec Task Offload Yes No No

SR-IOV with Live Migration Yes No2 No2

Storage Encryption Yes No No1 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.
