Hi,

We are thinking of purchasing a hardware network load balancer for our Exchange servers

https://technet.microsoft.com/en-us/library/jj898588%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396

We currently have two servers (both running as a client access server and a mailbox server) which are in a DAG, Mailboxes are shared between them over 8 databases. Is it possible to put a hardware based network load balancer (probably a Barracuda) in front of these servers?

I have read in the article below that using WNLB would not work in front of servers in a mailbox dag and that you would need to put the Client access role on a different server - but I wasn't sure if that just applied to the WNLB or any network load balancer such as a hardware based barracuda?

Thanks in advance

That applies only to the Windows Network Load Balancer.  Not only would I not recommend anyone use WNLB, but you cannot have the Windows Failover Cluster components exist on the same machine as the WNLB components.

Absolutely you can do that!

Thanks very much, that answers my question :)
