자세한 설명

The Get-NetAdapterSriov cmdlet gets the Single-Root I/O Virtualization (SR-IOV) properties of network adapters that support SR-IOV. SR-IOV enables network traffic to by-pass the software switch layer of the Hyper-V virtualization stack. As a result, the I/O overhead in the software emulation layer is diminished and can achieve network performance that is nearly the same performance as in non-virtualized environments. Run this cmdlet to display how the hardware is set to support SR-IOV. This cmdlet will display the properties of the network adapter that relate to SR-IOV, such as the number of ports, and virtual functions (VFs). The property SriovSupport indicates potential reasons for SR-IOV not functioning properly. The possible values for SriovSupport include the following.
- Unknown: Ensure that the computer has hardware support for SR-IOV and that I/O virtualization is enabled in the BIOS. Also ensure that the computer is running Windows Server® 2012 and later.
- Supported: SR-IOV is supported and should be functioning properly.
- MissingAcs: SR-IOV cannot be used on this network adapter as the PCI Express hardware does not support Access Control Services (ACS). This device may work in an alternate PCI Express slot. Contact your hardware vendor for further information.
- MissingPfDriver: SR-IOV cannot be used on this network adapter as the device or device driver does not support SR-IOV. If the network adapter supports SR-IOV, contact the hardware vendor for an updated driver.
- NoBusResources: SR-IOV cannot be used on this network adapter as there are not enough PCI Express bus numbers available.
- NoIoMmuSupport: SR-IOV cannot be used on this computer because of one or more of the following reasons.
- - The processor does not support second level address translation (SLAT). For processors manufactured by Intel Corporation™ (Intel™), this feature might be referred to as Extended Page Tables (EPT). For processors manufactured by Advanced Micro Devices™ (AMD™), this feature might be referred to as Rapid Virtualization Indexing (RVI) or Nested Page Tables (NPT).
- - The chipset on the computer does not do Interrupt and/or DMA remapping, without which SR-IOV cannot be supported.
- - This computer has been configured to disable the use of I/O remapping hardware.
- NoVfBarSpace: SR-IOV cannot be used on this network adapter as there are not enough PCI Express BAR resources available. This may be due to incorrect or partial configuration in the computer BIOS for Interrupt and DMA remapping. These settings may be referred to as SR-IOV or input/output memory management unit (IOMMU) support. If the computer BIOS is correctly configured, this device may work in an alternate PCI Express slot. Contact the original equipment manufacturer of the computer for further information.
- NoOscSupport: To use SR-IOV on this computer, the computer BIOS must be updated to allow Windows Server 2012 and later to control PCI Express using _OSC HandOff. Contact the original equipment manufacturer of the computer for an update.
