I had this question today, probably sparked by my post earlier where a showed a single-node cluster being able to leverage HCI Mesh to mount a remote vSAN Datastore. The question was if this also works with 2-node vSAN or with a vSAN Stretched Cluster. Unfortunately, the answer is no, a 2-node cluster or a vSAN Stretched Cluster is not supported with HCI Mesh today. Yes, this is a hard limit today, meaning that the “health check”, which is done before mounting the datastore, will actually report the issue and not allow it to progress. You can imagine that this is the result of the latency and bandwidth/throughput requirements there are in place for vSAN HCI Mesh today. This may, or may not, change over time.
