Issue/Introduction
Virtual Machine Compatibility “ESXi 7.0 ad later” (vHW v17) introduces support of Intel Xeon Scalable Gen2 processor, Cascade Lake (82xx, 62xx, 52xx, 42xx). The i3en.metal host type uses Intel Xeon Platinum 8259CL CPU. Intel Cascade Lake provides new capabilities such as DLBoost, AVX-512 and VNNI that are available in i3en.metal instances. The Virtual hardware version used by the VM needs to be at Version 17 or above for these new features to be exposed to the workloads running in the VM. This KB provides further details about these new CPU capabilities of i3en.metal and guidance on creating virtual machines with hardware version 17 to leverage these features.
Symptoms:
“VMware Cloud on AWS uses Virtual hardware version 14 as default, set to ESXI 6.7 and later”. If the VM on a VMware Cloud on AWS SDDC is built with default settings, your applications within the VM may not run efficiently on the i3en.metal host type with VMware Cloud on AWS.
