regarding the chapter dedicated to availability domain in Nutanix Bible (http://nutanixbible.com/index.html#availability-domains-WnIbC8TM)
I have questions from a customer i was not able to answer.
This chapter begins by : Availability Domains (aka node/block/rack
awareness) is a key struct for distributed systems to abide by for determining component and data placement.
Node awareness is the default feature : ok
I understand block awareness as described in the bible.
But nowhere else bible's team talk about rack awareness
I will be audacious : would it be possible to create a Nutanix cluster on two sites (latency = 60microsecondes) with rack awareness (rack = site) ?
and more audacious : a customer with three sites (latency of each with the others = 60microsecondes). Is that to create a 3 sites cluster with rack awareness ? In case of failure of a site, the reconstruction will be done between the 2 stayed alive.
Is that possible ?
if yes how ?
if not why ?
