I just need clarification on how to setup DAG for exchange servers with shared storage (if supported). With the scenaric below, do I present that same 4TB LUN to both EX1 and EX2 or do I need to create a separate LUN for each server (EX1 & EX2). Also, what is your opinion with HAProxyas a VM load balancer? We're kind of short with our IT budget and would like to implement it as a temp. solution. Thanks
SAN : created 4TB LUN for mailboxes
EX1: mailbox role
EX2: mailbox role
EX3: witness server
