Ok, what about the plan, is one MBX and CAS in each site is fine?

Vijaya Babu Sekar

Yes it is more than enough. before. could you please confirm your organization strength that means how many mailbox required for your concern so that i can tell you how many mailbox server required.

Each site has one CAS server, it s more than enough.

Thanks

Ok,
My plan is to have 1400 MBX, im planning to use two Exchange servers each with MBX,CAS, one in the primary site and one in DR, is that fine.

Vijaya Babu Sekar

its small environment, you can use one CAS\MBX\HUB, If you want redundancy, you can use

2 CAS- Each site one CAS with CAS Array
2 MBX- with DAG ( with in site or site resilency)
2 HUB- for load balance purpose

Thanks

Thanks, I will eliminate the HW balancer at this stage and I will do dns changes in case, can I have just three servers ( two in the primary site and one in DR ) with DAG between the three?

If you are going to have no users in the second site, then that would work. That will allow you to have active/active/passive with a load balancer. Just ensure that all three servers are scaled to take all of the users.

@sembee2, Yes, No CAS Array in exchange 2013, because no longer using RPC Client Access Service, i thought Exchange 2010. sorry for typo error.

Thanks

Last question before I accept , can I have one MBX/CAS in the primary and one MBX/CAS in the other location and add the third one later in the primary site.

Thanks
