Manage GPU devices
|
|
ARM hosts do not support GPU device management. |
CAS integrates the NVIDIA Virtual GPU technology to provide GPU virtualization services for VM users in Windows 10, 3D graphic design, and multimedia environments. GPU virtualization increases GPU resource usage by allowing multiple VMs to share a physical GPU resource.
The typical vGPU application procedure is as follows:
Add vGPUs on hosts.
Add a vGPU iRS service.
Add vGPUs for VMs.
Install the NVIDIA driver on VMs and connect to the vGPU license server.
Restrictions and guidelines
Before virtualizing a physical GPU, disable the Error Correcting Code (ECC) feature. After editing the ECC state, restart the host to make the new ECC state effective.
A physical GPU can be virtualized into only one type of vGPUs.
A physical GPU no longer supports passthrough after being virtualized into vGPUs. A physical GPU in passthrough mode cannot be virtualized into vGPUs.
