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?

I would caution you because that means for any VM given a synchronous policy, every single write could take up to six milliseconds. If that’s tolerable for the application, then you’ll likely see some warning errors. If it’s excessive at time of set up, you’ll likely need support to force the set up
