What is best for use with Vsphere 7: VxRail or Nutanix nodes?


The purpose is academic - we want to install GPU cards to test Automation with access to vGPU.

While both systems do a very good job within the nodal limits for scaling a compute environment - it is the networking layer that has the most impact on GPU sharing across a cluster.  From a practical perspective, VxRail nodes will typically offer a discount over native Nutanix nodes.  With Nutanix you also need servers, disk, networking and GPU's.  VxRail will be more integrated with sized nodes, Dell, Cisco or other networking and often the VSphere 7 licenses can be integrated - achieving a lower net cost.  


Testing for optimizations on either VSAN or Nutanix to see which favors a vGPU system would be something I would like to see quantified.  My guess is they are network constrained and differences between VxRail and a build your own Nutanix environment will be negligible for the same network.  Would be good to confirm if there is an optimal point - say 40Gbps vs 10Gbps or 100Gbps for the inter-GPU message passing.

"Nutanix node you will be running vSphere on top on the underlining Nutanix software" This description is incorrect. 


There is no "layer" between the hardware and the OS which is ESXI hypervisor on both cases.

Best option for vSphere 7 is the VxRail as it designed on VMware technology and built in integrates with vSphere, on a Nutanix node you will be running vSphere on top on the underlining Nutanix software.
