Technical white paper | Microsoft Windows Server 2012 SR-IOV Introduction Microsoft® Windows® Server 2012 supports Single Root I/O Virtualization (SR-IOV) as a new feature for Hyper-V. SR-IOV is included in a Peripheral Component Interconnect Special Interest Group (PCI-SIG) specification for partitioning PCI Express (PCIe) adapter bandwidth. Windows Server 2012 supports SR-IOV through SR-IOV capable PCIe network adapters (NICs).
PAGE 3
Technical white paper | Microsoft Windows Server 2012 SR-IOV must be of the same type because the Virtual Function inherits its Vendor ID and Device ID from its associated Physical Function’s configuration space fields. Windows Server 2012 recommended system configurations The PCI subsystem and the Windows Server 2012 kernel contain the core SR-IOV implementation, so both must support SRIOV. In addition, the PCIe NIC driver must support Virtual Functions and Physical Functions.

Technical white paper | Microsoft Windows Server 2012 SR-IOV Enabling the SR-IOV feature Figure 1 provides an overview of the process for enabling the SR-IOV feature. Figure 1: SR-IOV enablement process overview Prepare Materials As preparation for enabling the SR-IOV feature, make sure that your server and components are supported with Windows Server 2012 and SR-IOV: • Select a server from the recommended system platforms listed in Table 1 of the “SR-IOV-compliant ProLiant servers” section.

Technical white paper | Microsoft Windows Server 2012 SR-IOV Configure System After your server is prepared, you are ready to install the NIC. For information about the supported HP SR-IOV NICs, see the “ SR-IOV-compliant NICs” section. 1. Complete the following steps to install the SR-IOV-compliant PCIe NIC: A. Install SR-IOV stand up NIC into one of the PCIe slots. B. Insert the two GBIC modules into the ports. C. Connect the fibre cables.

Technical white paper | Microsoft Windows Server 2012 SR-IOV The Sriov Support field should report Supported as in Figure 6. Figure 6: Verify NIC support for SR-IOV If the Get-NetAdapterSriov does not report “Supported” and your NIC should support SR-IOV, check the following: • Make sure that your server supports SR-IOV. • Make sure that your server has the latest System ROM and firmware.

Technical white paper | Microsoft Windows Server 2012 SR-IOV Set up a virtual switch Complete the following steps to set up a virtual switch in SR-IOV mode using the Virtual Switch Manager: 1. 2. 3. 4. 5. Type a name for the virtual switch. See item A in Figure 6. We use the name “HP SRIOV” in this example. Click on the radion button for External network. See item B in Figure 6. Choose port to which you want to connect to the virtual switch. See item C in Figure 6.

Technical white paper | Microsoft Windows Server 2012 SR-IOV Enable SR-IOV on a Virtual Machine To enable SR-IOV on the VM, complete the following steps: 1. 2. 3. Choose the virtual switch that you created previously. See item A in Figure 8. Under the Hardware Acceleration option, click the check the box to Enable SR-IOV. See item B in Figure 8. Click Apply, and then click OK. Figure 8: Enable SR-IOV for your VM 4. 5. 6. 7. Verify that there no boxes checked in the Advanced Features.

Technical white paper | Microsoft Windows Server 2012 SR-IOV Figure 9: Start the VM Making sure that the VM is enabled To test the SR-IOV physical functions (PF) and virtual functions (VF), complete the following steps: 1. 2. Launch Windows PowerShell 3.0. To confirm that IOV support and IovVirtualFunction are enabled, type the PowerShell command: get-vmswitch | fl 3. 4. Verify the VM name. Verify the following parameters.
PAGE 13
Technical white paper | Microsoft Windows Server 2012 SR-IOV To confirm that the VM is active in Hyper-V Manager, click the Networking tab of the test VM and confirm the Status indicates OK (SR-IOV active). See Figure 10. Figure 10: Confirm the VM’s PF and VF functionality 5. Connect the fibre cables to the switch as necessary for your network environment.
