Exchange 2016 - High Availability RRS feed

  • Question

  • Dear Folks,

    For a customer we are in the process of proposing solution for Exchange 2013 to Exchange 2016 On-Premises Migration. Customer has over 25000/- mailboxes and pretty large infrastructure. Customer also wants to keep primary and DR site plus customer wants to have LAG database copies for up to last 2 days.

    We have done the initial assessment and we are proposing 8 servers in primary site and 8 servers in DR site - so there will be single DAG with 2 more servers for LAG copy at primary site and 2 more servers in DR site. It will make total 20 servers in Single DAG.

    This is how customer is insisting to propose but as per my understanding single DAG can have up to 16 Servers. please suggest is this correct understanding. secondly, what should be better design along with LAG copies of databases.

    Thanks, Sheeraz
