Is there a minimum or recommended switch port buffer size? I plan on using eth0 and eth 1 to be connected to two different 10G switches but was wondering if there is a minimum buffer size or switch port requirement?

If anything, you may occasionally need to change the buffer size for the Nics on the hyperviosr hardware side. Please review:

Based on document above, the number you look for might be 4096 bytes, but as I mentioned I would not change things on switch side, as I mentioned most switches should be able to handle the type of traffic hyper converged systems will generate.

Hi
You can read the AHV Networking best practices guide to better design your network infra for Nutanix HCI.
this is from the best practices guide above :
“To prevent packet loss from oversubscription, avoid switches that use a shared port-buffer architecture.”
we don’t have an exact port buffer size recommendation.
Normally with HCI and SDS deployments, it is good to use Line-rate, non-blocking switches with larger buffers for production workloads.Use an 802.3-2012 standards-compliant switch that has low latency, cut-through design and provides predictable, consistent traffic latency.
Hope this helps
