Im here to just ask you about some tips and best practices when setting up a cluster HA setup on a certain costumer.
The customer already have a EG 5000 running in standalone mode but im setting up a new virtual machine for host a new virtual email gateway appliance which will be used to build a high avaiability cluster between these two nodes (Master/Failover)
I dont have any expertise with mcafee email gateway, but im looking for learn how to achieve this job as fast i can by reading the product guide (which i did not find any information about clustering) and also on this community
What will be necessary to setup a new HA cluster for this setup above?
Is there any requirement about setting up a new entry on the external DNS pointing a new record for the new machine or it would not be necessary when it relates for cluster HA (high avaiability, active, Standby) ?
Is there any requirement on the customer enviroment (firewall, dns, routers, microsoft exchange) which must be configured to set up a new MEG HA cluster to receive and send emails?
Accept as much tips you could gave me to help me, really thanks guys!!!!
