Configuring Hardware Resource Settings

You can configure and allocate expansion card resources for different software QTS applications in Hardware Resource Settings. You can also configure Thunderbolt expansion cards, TPU modules, or network expansion cards that support SR-IOV.

For details, see Viewing Single Root I/O Virtualization (SR-IOV) Settings

  1. Go to Control Panel > System > Hardware > Hardware Resources.

    QTS lists the available expansion cards.

  2. Identify the expansion cards you want to configure.
  3. Under Resource Use, select an OS or an application.

    Some functions are only applicable for certain models and expansion cards.

    OS or Application



    QTS applications share expansion card resources for transcoding.

    • Select Hardware Transcoding to allow QTS software to use expansion card resources to speed up transcoding tasks. Only one card can be assigned to hardware transcoding.

    • Select Output to use expansion card resources for video output of HD Station or Linux Station. Only one card can be assigned to output.

    Virtualization Station

    Virtualization Station has exclusive use of all expansion card resources.

    Container Station

    Container Station has exclusive use of all expansion card resources.

  4. Click Apply.

Configuring TPU Settings

You can configure the priority level and maximum number of Tensor Processing Units (TPU) allocated to an app.

  • The system will not run apps with lower TPU priority levels until the TPU resource is released from running higher priority apps.

  • The maximum number of TPUs you can allocate to an app is 4.

  1. Go to Control Panel > System > Hardware > Hardware Resource.
  2. Locate the TPU device from the list.
  3. Click on the TPU device.

    The Priority window appears.

  4. Select an app.
  5. Select a TPU priority level.
  6. Select the maximum number of TPUs.
  7. Click Apply.

Viewing Single Root I/O Virtualization (SR-IOV) Settings

You can view all Single Root I/O Virtualization (SR-IOV) devices mapped to your virtual machines on the Control Panel > Hardware > Hardware Resources page. The SR-IOV interface is a hardware specification that allows a single PCIe device, such as a network adapter, to appear as multiple physical devices to the hypervisor. Because each device is directly assigned to an instance, it can bypass the hypervisor and virtual switch layer to achieve low latency and performance matching in nonvirtualized environments. SR-IOV achieves this through the following types of functions:

  • Physical Function (PF): These are PCIe devices that have SR-IOV capabilities. PFs are managed and configured in the same way as PCIe devices.

  • Virtual Function (VF): These are lightweight PCIe functions that only process I/O. Because each VF is derived from a PF, the device hardware limits the number of VFs a device can have. A VF shares one or more hardware resources of the device, such as a memory or network port.

    The following table lists all SR-IOV functions you can view in Hardware Resource:





SR-IOV Devices

Lists all the SR-IOV devices that are mapped to your virtual machine (VM).



Displays the physical function (PF) or virtual function (VF) configured to the SR-IOV device.



Shows the virtual machines that are mapped to the PF or VF.



Click to enlarge or minimize the SR-IOV device panel window.


Show or Hide

Click to show or hide the list of SR-IOV device details.



Shows the slot/port type and slot/port number.
