Somehow I get this question a lot lately, and it seems there’s still some conflicting documentation and messaging out there, is vSAN ESA supported with 10GbE networking or not? The answer is simple, yes it is supported officially. Although you may see some, outdated, blogs and docs state that 25GbE is the minimum, this was actually revised with the introduction of the AF-0 Ready Node configuration for vSAN ESA.
Now, I can fully understand people want this in writing, and after some digging I actually found an update documentation page on the Broadcom website that describes the vSAN ESA and vSAN OSA networking requirements. You can find it here: VMware vSAN – Physical NIC Requirements.
Thank you for this blog post, Duncan!
I was one of the customers asking this question lately… So, can I assume that 10GbE is supported with vSAN ESA in general (as the linked article suggests), or is it only supported with AF-0 nodes (as I heard before)?

Yes, it is supported. I always just start with the lowest ReadyNode option and then increase what I need, much easier and means it is always supported.
