[All 5V0-21.21 Questions]

As a part of a network hardware refresh project, all the network switches have been replaced with a newer, high-performance model. After the replacement, the company users started experiencing slowness on the applications hosted on their vSAN-backed VMs.

The vSAN administrator checked the vSAN Network Health status and noticed that the "Hosts large ping test" has failed.

What could be the cause of this performance degradation issue?

Don't forget about the vDS switch - if it doesn't have MTU 9K configured, that could be the issue too.

It could also be a problem with the ToR switch not having the correct MTU configuration.

But what if the MTU 9K is actually not configured on the hosts VMnic ports?

I agree, it's likely that the MTU 9K is not configured on the hosts' vSAN vMKernel ports.

I think the cause of the performance issue could be related to the MTU configuration.
