App and CM layer install

[Cognos8]

HI,

In C10.1 environment  we have installed  like below

Existing method
================
CM and dispatcher component installed in A server. BUt disabled the dispatcher component
CM and dispatcher component installed in B server. Disabled the CM services.
CM and dispatcher component installed in C server. Not disabled beacuse it acts as Dispatcher and SCM.

Proposed
===================
I am suggesting as Install CM alone in A  server.
Install dispatcher alone in B server.
install diaptcher and CM component in 2 different directory in C server. It will run in 2 different ( dispatcher and CM services) services.

My QUESTION is WHAT  harm in the existing method  and what advantages in proposed method. I wish to know direct answer. as far as i know it is avoid unecessary install, improve the performance or memory.. But how can i proove this proposed one is good.

It's better to install each seperately as they will each have their own Java process and that java process will be independant of all the other and use it's own memory space.

With Both the CM and App(dispatcher) installed in the same directory/install they have to share the java process and memory.

What you are proposing will add redundancy for the DM and much better utilization of the available memory.
