Suggested Answer: B

The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10.

vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6815-sub3

Hmm, 10 Gb/s seems a bit low for a new all-flash vSAN cluster. I'm going with 25 Gb/s, that should give us the performance we need.

Wait, so we need at least 25 Gb/s for each host? That's a lot of bandwidth! I hope my home network can handle it.

Hmm, I'm not sure. I'll have to double check the documentation to confirm the correct answer.

I believe it's actually 10 Gb/s per host, based on the vSAN Original Storage Architecture.
