Hi,

I have all exchange role installed all is working fine without edge role. CAS is load balance with nbl and MBX is with DAG. If i involve edge do i have to deploy multiple role and do same NBL for load balance, if i invovle what would be my dns setting will this point to edge role, what owa url will point to edge or remains on cas if on edge do Edge have to redirect to cas or ressovle itself the request. 

Your Guideline regarding edge

thanks 

Edge has nothing to do with CAS. It only handles SMTP traffic which has communication with hub transport service running on mailbox role. You do not need load balancer. Multiple MX records serve the purpose HA and LB.

Hi shani,

Thank you for your question.

If i involve edge do i have to deploy multiple role and do same NBL for load balance

A: if we want to receive/send email from/to Internet though Edge, we could deploy Edge server in DMZ, if we want to configure Edge server  redundancy and load  balance, we could install multiple Edge servers in DMZ. We suggest we put a Hub Transport server into each site, and then establish a 1:1 ratio of Hub Transport to Edge Transport servers. In such a configuration, each Hub Transport server is synchronized to only one Edge Transport server. And each Edge Transport server connect to a separate Internet connection through different ISPs. Servicing multiple Edge Transport servers with a single ISP creates a potential single point of failure. Using multiple ISPs ensures that if you will still have Internet access, even if there is an ISP problem.

what owa url will point to edge or remains on cas if on edge do Edge have to redirect to cas or ressovle itself the request.

A: As zhens said, we didnt modify the URL to point to Edge. We just have MX record in ISP.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim
