MDSM with VSX Architecture Recommendations and Configuration Guide

[Vladimir]

This is sanitized version of the document describing multi-site MDS with VSX clustered deployment I have been working on about a year ago.

While it was done with R77.30, I believe most of it may still be relevant with R80.X.

In the beginning it addresses the utilization of the older equipment that is being replaced or upgraded and possible ways to maximize its usefulness. You may skip it if it is not applicable to your situation.
