Im planning an Exchange 2013 Installation with maximum high availability and easy upgrade when users are getting more and more.
Im thinking of 2 servers for each role for Start.
2 CAS to create a cas array and 2 MBX to create DAG.
Also im thinging to install 2 EDGE Servers ( exchange2010) with forefront antispam.
Any ideas about the load balancing of the CAS Array ? Also any tips maybe for the whole installation ?
