1. What's New in Windows Server 2012 Hyper-V, Part 2 Jeff Woolsey Windows Server & Cloud Microsoft Corporation VIR309

5. Windows Server 2012 Networking

6. How do I ensure network multi-tenancy? IP Address Management is a pain. What if VMs are competing for bandwidth? Fully Leverage Network Fabric How do I integrate with existing fabric? Network Metering? Can I dedicate a NIC to a workload?

17. Dynamic Virtual Machine Queue (VMQ) is a feature available to computers running Windows Server 2008 R2 with the Hyper-V server role installed, that have VMQ-capable network hardware. VMQ uses hardware packet filtering to deliver packet data from an external virtual machine network directly to virtual machines, which reduces the overhead of routing packets and copying them from the management operating system to the virtual machine.

22. IPsec Task Offload: Microsoft expects deployment of Internet Protocol security (IPsec) to increase significantly in the coming years. The large demands placed on the CPU by the IPsec integrity and encryption algorithms can reduce the performance of your network connections. IPsec Task Offload is a technology built into the Windows operating system that moves this workload from the main computer's CPU to a dedicated processor on the network adapter. SR-IOV is a specification that allows a PCIe device to appear to be multiple separate physical PCIe devices. The SR-IOV specification was created and is maintained by the PCI SIG, with the idea that a standard specification will help promote interoperability. SR-IOV works by introducing the idea of physical functions (PFs) and virtual functions (VFs). Physical functions (PFs) are full-featured PCIe functions; virtual functions (VFs) are “lightweight” functions that lack configuration resources. Dynamic Virtual Machine Queue (VMQ) is a feature available to computers running Windows Server 2008 R2 with the Hyper-V server role installed, that have VMQ-capable network hardware. VMQ uses hardware packet filtering to deliver packet data from an external virtual machine network directly to virtual machines, which reduces the overhead of routing packets and copying them from the management operating system to the virtual machine.

26. Complete VM Mobility

27. Don’t provide new features that preclude Live Migration. I want to be able to securely move any part of a VM anywhere at anytime. No Limits. No Downtime Servicing SAN Upgrades/Migrations When VMs migrate, move the historical data with the VM Fully Leverage hardware to speed migrations
