The user might get confused with SCM HA and Ratis if they don't have understanding on how HA is implemented.
We can remove this line completely as the end user doesn't have to know about Ratis to run single or multiple (HA) SCM.

There is a typo "all the Datanodes" in the English version
Datanodes are sending all the reports (Container reports, Pipeline reports...) to *all* the Datanodes parallel.

For "### Current SCM HA Security limitation", I think we can remove the first item, and change the second item to
"Un-secure HA cluster upgrade to secure HA cluster is not supported."
