Configuring New Front End Servers
You are now ready to set up the consolidated Front End Servers that will be used in the load balanced array. These servers will be added to your existing pool, and they will use the same back-end database. Follow the standard setup procedure for an Enterprise Edition server, and add each server to your existing pool. In our example, this procedure would involve the following steps:
- Obtain a new physical server, assign it an IP address of
10.0.1.41, install the prerequisite operating system for Office
Communications Server 2007 R2, and then install IIS.
- Name the computer
ocsfe01.contoso.com, and then add it to your enterprise DNS
server.
- Run the Office Communications Server 2007 R2 Enterprise Edition
setup.
- Select the option to add a consolidated Enterprise Edition
server to an existing pool.
If your existing server is a Standard Edition server, you will need to create an Enterprise Edition pool on the associated back-end database at this stage. - Select
ocspool.contoso.comas the existing pool and add your new
consolidated Front End Server to the pool.
- When you request the certificate, set the Subject Name to
ocspool.contoso.comand add
ocsfe01.contoso.comand
sip.contoso.comas Subject Alternate Names.
- Run the Activation portion of the setup procedure on
ocsfe01and during the wizard
, use the existing service account and start all Office
Communications Server services.
- Configure IIS to allow load balancer FQDN loopback as described
in
Configuring IIS
to Allow Load Balancer FQDN for Loopbackin the Deploying Office
Communications Server 2007 R2 Enterprise Edition documentation.
- Repeat the above steps on a second physical server with IP
address 10.0.1.42 and named
ocsfe02.contoso.com.
Ensure the following requirements are met:
- The two Front End Servers must be capable of routing to each
other. There can be no NAT device in this path of communication.
Any such device will prevent successful intrapool communication
over RPC.
- Front End Servers must have access to the Active Directory
Domain Services environment.
- Front End Servers must have static IP addresses that can be
used to configure them in the load balancer. In addition, these IP
addresses must have DNS registrations.
