Hi Yogesh,
We are going down the same path as you had. I wanted to see if you were able to find a solution. The only solution we have found is running MSCS on VMWare which our infrastructure team will not support because it is cumbersome to support and maintain. We were looking for any other solution to have HA and 99.99% uptime.
Also, FYI, the note which Deepak refers to actually gives the details on how to set up HA for MaxDB 7.8 and 7.9. We actually originally made the same mistake as you in reading the note incorrectly. The Reason and Prerequisite is "there is no tool-supported cluster integration for the Content Server databases". The solution for the problem is the note.
Hope this helps!
Avi
