Single route I/O virtualization is introduced as a performance-enhancing feature for virtualization. The roles of hardware and operating system are presented.
- [Instructor] A couple of chapters ago,…we were configuring Receive Side Scaling,…and I told you to make sure that SR-IOV was turned off.…Well, we've reached a point where I want to explain why…and show you what SR-IOV is and what it does,…so that you can make the decision…about which is best for your environment.…Remember that RSS is a technology…to better utilize your processors…and virtual machine queues, including multi-queues,…are an even smarter way of how to use…the multiple cores in a server…and how that can help in a Hyper-V situation.…
Now single route IO virtualization…is another way to speed things up.…In single-route IO virtualization…we're going to take the hypervisor,…including the virtual switch out of the process altogether.…In fact, this technology is designed to take the CPU…of the host out of the process as much as possible.…What happens is this,…SR-IOV groups the queues into pools…that can be recognized by both the motherboard chipset…and by Windows Server,…then each is mapped directly to the memory space…
