Hi, Just wanted to see what others in similar scenarios are doing with similar setups.
We have a 2x Server 2012 R2 node Cluster with Hyper-v role with shared ISCSI storage supporting 40 users with around 60 mailboxes running the following VM's :
Active Directory, Exchange 2013, GFI Mail Archiver and File & Print.
Going Office 365 was not an option to consider for us at the time of implementation (nor is it now) for various reasons and On-Premise was the only option.
We understand Microsoft's Preferred Architecture and recommended best practice for Exchange 2013 High Availability inside a Virtual Machine requires a DAG and not to make the machine Highly Available at the Hyper-v cluster level. However we see running the additional DAG member as an extra resource and an overkill for such a small setup. We appreciate that High availability comes at a cost but just wanted to see what everyone else is doing and whether or not anyone else has steered away from the preferred architecture and made Exchange 2013 Highly Available at the Hyper-v cluster level without a DAG.
Our concerns are mainly around Database Integrity, etc.. during Live Migration.
Any help, advice or experience is greatly appreciated
