This produces the VIB name in the first column of output, such as You can determine whether the NVIDIA ESXi Host Driver is present, when logged in to the ESXi server If the NVIDIA ESXi Host Driver (that supports vGPUs) is not installed for earlier pre-MIG uses then MIG by definition will not be present. Enabling the MIG Feature for a GPU on the ESXi Hostīy default, MIG is disabled at the host server level. It applies in exactly the same way for MIG as it does for pre-MIG vGPU environments (i.e. This part of the setup is described in full section 1.1 of the original vGPU usage article and we won’t repeat it here. A GPU Instance is associated with an SR-IOV Virtual Function at VM/vGPU boot-up time. ![]() Think of SR-IOV and the vGPU driver as wrappers around a GPU Instance. SR-IOV is not a pre-requisite for MIG in itself. SR-IOV is a pre-requisite for running vGPUs on MIG. In the UI above, the important entry to note is the enablement of the “SR-IOV Global” value, seen in the last line. This may be different on your own host servers, depending on your vendor.įigure 2: Configure SR-IOV Global using the iDRAC user interface on a Dell server. Here is an image of how this is done in the case of a Dell R740 server, using the iDRAC interface. Pre-requisites for MIG Enablement Global SR-IOVīefore we can enable MIG, we first need to enable the “Global SR-IOV” feature at the vSphere host BIOS level through the server management console, or iDRAC. vCenter 7 Update 2 along with vSphere 7 Update 2 will automatically create the correctly sized GPU Instance for you and the associated Compute Instance, when you choose a vGPU profile for a MIG-backed vGPU. NOTE: The process for creating GPU Instances and Compute instances described below is now much more automated with vSphere 7 Update 2 and later. As a reminder, we include the outline MIG architecture again here for your reference. ![]() ![]() We already understand from part 1 that a GPU Instance represents a slice of a physical GPU capturing memory, a fraction of the overall streaming multiprocessors (SMs) or cores and the hardware pathways to those items, such as the crossbars and L2 cache. Or they can dedicate a full GPU to one VM and one user, if the need is there to do that. The vSphere administrator can give assurance to the vGPU consumer, a data scientist or machine learning practitioner, that their portion of the GPU is isolated for their use only. This allows the vSphere administrator to treat their GPU power in a cloud provider way and to maximize the utilization of the physical GPU by packing workloads onto it that are independent of each other. As a brief recap, the value of MIG to the vSphere user is MIG’s ability to do strict isolation between one vGPU’s share of a physical GPU and another on the same host server. In this second article on MIG, we dig a little deeper into the setup of MIG on vSphere and show how they work together. MIG works on the A100 GPU and others from NVIDIA’s Ampere range and it is compatible with CUDA Version 11. Right-click on the VM and select Edit Settings.In part 1 of this series on Multi-Instance GPUs (MIG), we saw the concepts in the NVIDIA MIG feature set deployed on vSphere 7 in technical preview. The first setting we need to change is to reserve the memory. Have your VM powered off to perform these steps. It can be helpful to reference the release notes for the various versions in case you are looking for a feature that was added. ![]() The VM that I’m prepping will be used for a Horizon Instant Clone desktop pool, but the process is similar for full-clone virtual machines as well.īe sure your VM is at least hardware version 11. After installing the NVIDIA drivers we won’t be able to use the vSphere console so having RDP or another tool available will be critical to complete the configuration. I’ll cover the basic steps here, but more information can be found on Tech Zone.īe sure that you have a way to remote into the virtual machine other than using the vSphere console. You have an NVIDIA GPU installed in your server and the NVIDIA licensing server configured, now you need to prep your virtual desktops to utilize the GPU.
