Windows Server "8" Hyper-V - Everything You Wanted to Know about Single-Root Input/Output

 

Really loved this series !!!!!

With Windows Server “8” Hyper-V we’re taking network performance to the next level. Need to virtualize scale up applications with high throughput, low latency requirements? No problem.

Windows Server “8” Hyper-V now provides Single-Root Input/Output (SR-IOV) Networking.

Part 1: https://blogs.technet.com/b/jhoward/archive/2012/03/12/everything-you-wanted-to-know-about-sr-iov-in-hyper-v-part-1.aspx 

Part 1 discusses emulated versus software devices, the pros and cons and constraints of each and why Microsoft is investing in SR-IOV.

 Part 2: https://blogs.technet.com/b/jhoward/archive/2012/03/13/everything-you-wanted-to-know-about-sr-iov-in-hyper-v-part-2.aspx 

Part 2 discusses the SR-IOV standard, physical functions (PFs) virtual functions (VFs) and the hardware requirements to make SR-IOV even possible.

Part 3: https://blogs.technet.com/b/jhoward/archive/2012/03/14/everything-you-wanted-to-know-about-sr-iov-in-hyper-v-part-3.aspx 

Part 3 discusses device drivers and how they function in an SR-IOV environment as well as screenshots of an SR-IOV NIC within a Hyper-V VM.

Part 4: https://blogs.technet.com/b/jhoward/archive/2012/03/15/everything-you-wanted-to-know-about-sr-iov-in-hyper-v-part-4.aspx 

Part 4 discusses some of the low level necessary firmware and motherboard changes to make SR-IOV function and provides a pointer to an interesting presentation given 4 years ago at WinHEC 2008 by Jake Oshins that provides further insight into SR-IOV.

Part 5: https://blogs.technet.com/b/jhoward/archive/2012/03/16/everything-you-wanted-to-know-about-sr-iov-in-hyper-v-part-5.aspx 

Part 5 explains the IO path with SR-IOV enabled, covers SR-IOV configuration via the UI and a deeper dive into PowerShell.

Part 6: https://blogs.technet.com/b/jhoward/archive/2012/03/19/everything-you-wanted-to-know-about-sr-iov-in-hyper-v-part-6.aspx 

Part 6 discusses SR-IOV and Live Migration in detail. It covers the engineering challenge of making SR-IOV work with Live Migration (not trivial folks) and even includes a video that demonstrates a virtual machine
with an SR-IOV NIC under load being Live Migrated. There’s even a link to a WinHEC 2006 presentation (told you we’ve been looking at this technology a while…)
