Everything you wanted to know about SR-IOV in Hyper-V Part 2


In part 1, I discussed why Microsoft has been investing in SR-IOV for device I/O from virtual machines. The key points were to reduce latency, increase throughput, lower compute overhead, and for future scalability. Part two takes a look at SR-IOV from a hardware perspective.

For those who didn’t take up my offer of the light bed time reading of the SR-IOV specs (or don’t have access), let me summarize what SR-IOV is. And to be clear, when I say “SR-IOV”, take it to include closely associated specifications or additions to PCI Express specifications such as

  • ATS (Address Translation Services) – A PCI Express Protocol that allows a device to fetch translations from an IOMMU (Input/Output Memory Management Unit).
  • ARI (Alternate Routing Interpretation) – A PCI Express switch change and device change which allows a device to occupy more than eight RIDs on a single bus
  • ACS (Access Control Services) – A PCI Express switch feature that forces peer-to-peer traffic upstream so that it can be translated by an IOMMU.
