asked on Deploying DAG on Exchange 2013 Standard edition
Hi All,
I’m about to deploy 2x new Exchange Server 2013 SP1 Standard edition DAG on the Windows Server 2012 R2 VMs.
I wanted to simplify the operational management as much as possible, hence I heard in the 2013 SP1 I can deploy the DAG without witness server (Dynamic Quorum) and also IP less DAG.
Can anyone here please share some pitfalls or disadvantage that I need to know before going through the path above ?
How many vNIC per mailbox server do I need it ?
Thanks in advance.

Todd,
Thanks for sharing the knowledge more about Exchange Server 2013. So it seems it is possible to combine the two feature:
IP-less DAG with Dynamic Quorum into the solution since I'm building the OS for the mailbox server on Windows Server 2012 R2.
OK, so if I install the additional Mailbox server in a new DAG config with 2013 SP1+CU16, can I still migrate my mailboxes to the new DAG-enabled DB ?

Regarding quorum (dynamic or otherwise), a witness server is required. In 2013 and 2010, if a witness server was not specified Exchange would attempt to locate an Exchange non-mailbox server to assign as a witness server. If no such server, then the creation of the DAG failed.
At the moment:
AD Site: HQ
PRODEXC01-VM - Stand Alone Mailbox + CAS
AD Site: Site-2
PRODEXC02-VM - Stand Alone Mailbox + CAS
AD Site: Site-3
PRODEXC03-VM - Stand Alone Mailbox + CAS
The proposed solution that I am building will be:
AD Site: HQ
PRODEXC01-VM - Stand Alone Mailbox + CAS
PRODEXC03-VM - Mailbox DAG1 - Member
AD Site: Site-2
PRODEXC02-VM - Stand Alone Mailbox + CAS
PRODEXC04-VM - Mailbox DAG1 - Member
AD Site: Site-3
PRODEXC03-VM - Stand Alone Mailbox + CAS
All of the mailbox DB is migrated accross to the DAG1 member. While the remaining CAS server is used for OWA & Active Sync.

Hi Todd,
Does placement of the Exchange transaction logs must also be on the same drive letter for the DAG member ?

The logs can be on a different drive from the databases but for a specific database must match for the other DAG members hosting that specific database. It may be best to have them on a separate drives depending on the type of storage/RAID is being used.
I assume that the second vNIC should have the different non-routable VLAN ?
