My current setup is having all exchange roles on single server in each site . ie 2 servers with DAG.

Now, i want to change the setup and make it more meaningful with HA option for all the roles. I am having 130 users but with hugh mailbox sizes.

I want to calculate load on these servers,so that i can ask for more servers in the setup.
Please suggest me. how should i procced and what will be ideal setup for me.

    You should use the Exchange 2010 Mailbox Server Role Requirements Calculator to determine the requirements for each of your servers. The calculator can be found here -

    The calculator will require some input regarding your current user profiles. You can use this script to gather that information from your current environment -

    The calculator will give you the requirements for those roles as well.
