This video will step you through the process I followed in my own environment running Dell PowerEdge R650s. Prior to recording this video, I experienced a few different errors due to not having an up to date bios and attempting to enable SR-IOV with three GPUs installed:
– SR-IOV Enabled / Needs reboot
– PST0208 System BIOS has halted
– UEFI0036 Unable to initialize the iDRAC Shared Memory Architecture (SMA) interface
– UEFI0134 Unable to allocate Memory Mapped Input Output (MMIO) resources for one or more PCIe devices because of insufficient MMIO memory
The video shows How to:
– Install the Intel Flex 140 / 170 GPU drivers on ESXi
– Upgrade the BIOS on Dell R650 using iDRAC 9
– Enable SR-IOV in Dell PowerEdge R650 BIOS
– Enable SR-IOV in vCenter
Completing the above steps is required in order to allow the GPU resources to be shared across multiple Virtual Machines (VM) in a vSphere 7 or vSphere 8 environment. To get the most out of the Intel Flex GPU line, it is recommended to use vSphere 8
0:00 – Intro
1:50 – ESXi and vCenter view with no drivers
2:50 – Download Intel Drivers for ESXi
4:00 – Place ESXi in Maintenance Mode
4:53 – How to enable SR-IOV using iDRAC
5:53 – Update Dell R650 BIOS using iDRAC
6:56 – Install Intel Drivers for ESXi
8:05 – BIOS update progress via iDRAC
8:34 – Enable SR-IOV in Dell R650 BIOS
10:15 – Confirm ESXi recognizes GPU
11:15 – Enable SR-IOV using vCenter
1. Place host in maintenance mode using the ESXi Host Client, vCenter, or the following command at the console:
esxcli system maintenanceMode set -e true
2. Verify host is in maintenance mode:
esxcli system maintenanceMode get
3. Open a console or SSH to your ESXi host and install the Intel drivers:
esxcli software component apply –no-sig-check -d /tmp/*Intel-idcgpu_*.zip
esxcli software component apply –no-sig-check -d /tmp/*Intel-idcgputools*.zip
4. Use iDRAC to upgrade your BIOS to latest version. If iDRAC is unavailable, use your available method to upgrade the BIOS
5. Enable SR-IOV in your BIOS. Using iDRAC, this is found under: Configuration BIOS Settings Integrated Devices SR-IOV Global Enable
6. Reboot your host after enabling SR-IOV
7. Exit maintenance mode: esxcli system maintenanceMode set -e false
8. Using either ESXi Host Client or vCenter, enable SR-IOV on each GPU listed in under PCI Devices, setting VF to 6 for FLEX 140 (I’m not certain about this)
9. Verify that all VFs show as Passthrough PCIe Devices
