Hi all, I am trying to setup zimbra (ZCS NE) with HA. Now as per the traditional document of zimbra I have to go through redhat cluster suite and setup the failover. My server setup is I have 10 servers in which I want to use 2 nodes of SMTP, 2 nodes of Mailbox, 2 nodes of LDAP and 2 Nodes of Load balancer (heartbeat). I have a 500GB of san coming and will only be mounted on the mailstore servers. For rest all they will be using the storage of machine itself. So update me if the designed solution is possible or not or else what are the challenges which we can face during deployment ??
