In my series of building a Lync Server 2013 High Availability environment, we have in the last three parts been setting up Load Balancing for the internal Lync Servers.

In Part 14 we have setup the Kemp Load Balancers that is uses internally

In Part 15 we have setup Load Balancing of the Office Web Apps Servers

In Part 16 we have setup a combination of DNS Load Balancing for the Lync Services and Hardware Load Balancing for the Web Services.

 

In this part we will look on how to setup the other alternative to the load balancing method in part 16, which is Load Balancing of all the Lync Services.

When using this method you must be sure that the Load Balancers can handle all the load of all the Lync Services.

Let’s first have a look at the topology builder, which you should configure like this:

I will not override the Internal Web Services, instead I will be using the default setting, which means that I will use the internal Frontend Pool Name for my web services.

Navigate to the top and set the monitor port to 5060 – this will prevent the Lync services to go crazy in the eventlog when the load balancer checks the sip port (5061/tcp)

In DNS your record for the Frontend Pool Name only points to the Virtual IP on the Load Balancer:

You should also have the other web service records in the exchangepro.dk dns zone:

 

Start by creating the Web Services like we did in Part 16.

Next we can setup the Lync services in the load balancer.

Below is an overview of the Lync Services that we need to create – Line 2-5 is created in the Part 16 guide.

I will in the below only create Line 7 so you can see the process.

overview1

Navigate to Virtual Service and Click Add New

Type the VIP, Port numver and give it a name. Then Click Add this virtual service

The Service Type must be Generic

Set the below parameters

Under Real Servers click Add New

Add the three frontend servers

Click Back twice and the service should be up a running.

Continue on the rest of the service in the above table.

Regarding the FE SIP (Line 10) you should set the Checked Port under Real Servers to port 5060 like below:

 

When all the services is created and the DNS records has been created you are now ready to enjoy you Load Balanced frontend servers.

 

In the next part we will be looking on how to Load Balance the Director Server.
