Everything you wanted to know about SR-IOV in Hyper-V Part 8

This part of the series is all about determining why SR-IOV may not be operational. As you will discover, there are several reasons, some of them obvious if you’ve followed all the parts so far, some more subtle. By the end of this part, you will be an expert! Assuming you have a switch in…

Everything you wanted to know about SR-IOV in Hyper-V Part 7

Only a few more topics in this series remain uncovered. This part of the series looks at resiliency with SR-IOV. By resiliency, I mean, of course, NIC teaming, otherwise known as Load Balancing/Failover (LBFO), the ability to aggregate network links or fail over should a link fail. I won’t get into the details of configuring…

Everything you wanted to know about SR-IOV in Hyper-V Part 6

Summarising the series so far, we’ve answered “Why SR-IOV?”, looked at hardware and firmware dependencies, and run through the user interface and PowerShell cmdlets to configure SR-IOV. Next on the agenda is how SR-IOV and Live Migration co-operate. In addition, there’s a video showing covering the configuration aspects of SR-IOV from the previous part which…

So far in this series, we’ve looked at the “why” question, and the hardware aspects of SR-IOV, and identified that to use SR-IOV in Hyper-V it is necessary to have system hardware support in the form of an IOMMU device, and a PCI Express device which has SR-IOV capabilities. Now it’s time to start taking…

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…
