Dell PowerEdge R740xd, AVX, and VMware ESXi 6.5
Hi,
I have a VMware virtual machine that requires the AVX instruction.
Have Dell PowerEdge R740xd - Qty: 2 Intel(R) Xeon(R) Platinum 8268 CPU @ 2.90GHz
1. Is the AVX enabled by default in the BIOS?
If not, which settings in the BIOS or in the iDRAC9 - Configuration do I enable AVX?
2. After enabling the AVX at the Dell R740xd BIOS level, is there a VMware ESXi 6.5 setting that I have enable AVX?
Thank you very much in advance,
Dean

Hi,
Thank you, DELL-Young E and DELL-Chris H.
I got the AVX instruction working for the VMware virtual machine.
1. In the VMware vSphere or vCenter, do "Upgrade VM Compatibility" on the virtual machine if needed.
2. In the VMware vSphere or vCenter, Enable EVC for Intel Hosts at the cluster level.

Hello, thanks for choosing Dell and welcome to our community.
Have you had a chance to have a read on this?
AVX(Advanced Vector Extensions)
https://dell.to/4bJZkYa
Can you also check you can see in BIOS as well?
Respectfully,

Hi DELL-Young E,
I have set the following:
"Dell Controlled Turbo" to Enabled
"Dell AVX Scaling Technology" to 2
"AVX ICCP Pre-Grant" 128 Heavy
I have saved and restart the Dell PowerEdge R740xd.
The VMware virtual machine still is not see the AVX.
Are there any other BIOS settings to be set?
Thank you,
Dean

DeanMichIT,
That should be what is required, so what I would suggest is that you also ensure that the sever is up to date on BIOS, iDrac, CPLD, etc.
Let us know if it is visible, if not then have you considered a newer version of ESXi to test?
