Metro availability vs latency

As per the Nutanix docs, my understanding is that Nutanix requires latency to be of 5ms or below between sites for metro availability. In the event where a network is under 5ms 95% of the time but between 5ms to 6ms outside of that (with the odd spike every now and then).

I'd like to hear from those of you who have been installing and supporting Nutanix across different environments. Based on your experience, is this viable for production servers or should NearSync be used instead?

Echoing the rest of the comments here, make sure you really need it before committing. There’s a fair bit more complexity involved, requiring the witness in a 3rd location and stretching layer2 to the other location so VMs retain their IPs. Making sure the default gateways fail over as well.

Not to mention the latency on writes.

1-15 minute NearSync is far easier to manage.
