GPU Specifications

A GPU specification defines the specification of the frame count, video memory, resolution, and other parameters of a GPU. A GPU specification can be either a physical GPU (pGPU) specification or a virtual GPU (vGPU) specification.

GPU Specifications Management Page

In the navigation pane of the ZStack Private Cloud UI, choose Resource Pool > GPU Specifications. Then, the GPU Specifications management page is displayed, as shown in Figure 1.
Figure 1. GPU Specifications Management Page


The GPU specifications management page has the following two tab pages:
  • pGPU: Displays a list of pGPU specifications scanned on all hosts in the cloud and the basic information about these pGPU specifications.
  • vGPU: Displays a list of available vGPU specifications generated from virtual segmentation and the basic information about these vGPU specifications.

pGPU Specifications

A pGPU specification defines the specification of the frame count, video memory, resolution, and other parameters of a pGPU.

pGPU Operations
You can perform the following operations on a pGPU specification:
  • Enable:

    Enable the pGPU specification. After enabled, the pGPU specification can be used to allocate a pGPU to a VM instance.

  • Disable:

    Disable the pGPU specification. After disabled, the pGPU specification cannot be used to allocate a pGPU to a VM instance.

  • Set ROM:
    Set ROM for a pGPU that corresponds to the pGPU specification for GPU passthrough.
    • You can obtain the required ROM file on the official website of the graphics card vendor.
    • After a ROM file is uploaded, it will be directly updated to the pGPU device corresponding to the pGPU specification you added before.
    • The newly uploaded ROM file will overwrite the previously uploaded ROM file.
  • Share To All:

    Share the pGPU specification to all accounts or projects. Then, the accounts or projects can use the pGPU specification to allocate a pGPU to VM instances.

  • Recall From All:

    Recall the pGPU specification globally. After a pGPU specification is recalled, the resources in use are not affected. However, the pGPU specification cannot be used to allocate a pGPU to a VM instance.

vGPU Specification

A vGPU specification is generated from a pGPU through virtual segmentation, and defines the specification of the frame count, video memory, resolution, and other parameters of a vGPU.

vGPU Operations
You can perform the following operations on a vGPU specification:
  • Enable:

    Enable the vGPU specification. After enabled, the vGPU specification can be used to allocate a vGPU to a VM instance.

  • Disable:

    Disable the vGPU specification. After disabled, the vGPU specification cannot be used to allocate a vGPU to a VM instance.

  • Share To All:

    Share the vGPU specification to all accounts or projects. Then, the accounts or projects can use the vGPU specification to allocate a vGPU to VM instances.

  • Recall From All:

    Recall the vGPU specification globally. After a vGPU specification is recalled, the resources in use are not affected. However, the vGPU specification cannot be used to allocate a vGPU to a VM instance.
