Exchange 2013 and Server Roles

One of the biggest surprise in Exchange 2013 is the reduction on the server roles. I remember days when Exchange server had to do all in once ( Exchange 5.5) later version of Exchange Servers 2007 and 2010 had server roles separations , the major roles ( HTS, CAS and MBX) Hub transport, Client Access, and Mailbox , also ( UM and EDGE) Unified messaging and Edge Server roles and when the most latest and greatest version Exchange is almost on the way ( it is listed in MSDN for download today) out Exchange 2013 let's take a look at the server roles…

• CAS ROLE ( Client Access Server)
• MBX ROLE ( Mailbox Server )

That is it, there will be no more roles, much simpler and efficient in a way and the future best practices as far as deploying roles may change , and all in one deployments might be recommended officially ( we will see (-: how that goes )

What happen to HTS , UM and EDGE roles ? The HTS ( Hub transport role) has been distributed in between CAS Server and MBX Server roles see below

UM role story is the same, so does EDGE, UM and EDGE roles are not there anymore (-:

I will get into more details in remains these two roles and their functions…..

CAS Array HLB or NLB

If you are planning or implementing  CAS Array and wondering what are the options for load balance your CAS servers here is quick reference to remember.

Options

• HLB ( hardware load balance ) solution, This is what is being recommended.
• SLB ( Software load balance) solution, This is also recommended.
• Windows NLB ( network load balancing) This is no longer recommended

If you have not see Rose Smith video presentation do not miss it , How Outlook connects to Exchange 2010 Client Access Server

The main reason why HLB & SLB  are recommended , these solutions provides “ Application awareness” and also managing CAS servers behind these type of deployment is very easy and efficient.

MAPI Request comes to HLB , HLB has CAS servers published within , Administrator easily can stop MAPI request going specific CAS server etc. These deployments are also far more stable and easy to configure IMO. I think we will see more official statement soon and expecting to see ending support recommendations to HLB with CAS in the near future.
