This is my guide on installing Microsoft Exchange Server 2010, the guide is intended only to deliver a know how about installing a highly available Exchange Server,
which means if you find this article useful for you, then you are going to need to do all the pre-calculations for installing to a production environment including , Software/hardware Requirements, Database Sizing … Etc..
So before i begin with installing Exchange Server , i would like to talk a little bit about Exchange Server Roles, for those who are new to Exchange Server 2007/2010 there has been a major change in the Exchange Server architecture starting Exchange 2007 and above, Exchange 2007 introduced server roles where each handles specific operations in the Exchange organization, those roles are
- CAS Client Access Server is responsible for handling authentication and redirection for Exchange server clients like outlook, OWA, and AciveSync for mobile devices, The CAS server handles those clients connection to their respective mailboxes.
- Hub Server is typically the email router, it routes all incoming or outgoing emails to their destinations.
- Mailbox Server hosts the Exchange Server Databases which includes users mailboxes and public folders
- Edge Server performs the same role of the HUB Server but placed typically in the perimeter network adding a layer of Security and protection provided by installed agents
- UM Server Unified Messaging server is used to integrate Exchange Server with and existing PBX system so that user mailboxes can be accessed by the telephone
Having explained the different roles for Exchange Server let’s start with deployment, i am going to deploy this lab in a virtual environment which is also supported in production environment by Microsoft see here so let’s take a look at our topology
Okay, so as we can see we are going to install a total of 4 servers for our Exchange environment , we are going to combine the CAS and HUB Server roles on a single server , and since we are doing a highly available solution we are going to install 2 nodes for this EX-HC-01 and EX-HC-02 , the other 2 nodes are going to carry our Exchange Databases therefore holding the Mailbox Server role .
EX-HC-01 : Exchange Server CAS/HUB Roles 1st Node [Server with 2 NICs]
EX-HC-02 : Exchange Server CAS/HUB Roles 2nd Node [Server with 2 NICs]
EX-MBX-01 : Exchange Server Mailbox 1st Node [Server with 2 NICs]
EX-MBX-02 : Exchange Server Mailbox 2nd Node [Server with 2 NICs]
DAG-01 : Database Availability Group ( will talk about this more later)
DC-01 : Active Directory Domain Controller
DC-02 : Active Directory Domain Controller with Certificate Services installed
Operating System Used for all servers : Microsoft Windows Server 2008 R2
okay, i’ll see you guys in Part 2 where we are going to start with preparing those servers for Exchange installation
