Load Balancing SCOM sdk service with Microsoft NLB Cluster

In SCOM, High Availability can be achieved at Management Server, Gateway Server and Agent level. If we drill down further more, we can even find ways to configure HA for SCOM console for uninterrupted monitoring

The sdk clients which connect to SCOM console can be made continuously available with Network Load Balancing. So, even in case of Management Server failure, the SCOM console will be operational

The SCOM Operations Console connections can be Highly available with Microsoft Network Load Balancing ( NLB ) , or using hardware Load Balancers or DNS aliases.

In this demo, I have chosen to use Microsoft Network Load Balancing

 

Prerequisites:

  1. Assign Static IP address instead of DHCP  to the SCOM Management Servers
  2. Microsoft Network Load Balancing feature to be enabled in the Management Servers
  3. Create NLB Cluster
  4. Add Nodes to the  Cluster
  5. Add cluster DNS-record to DNS zone

 

Primary Management Server: Server1.kartik.com

Secondary Management Server: Node2.kartik.com

Enable Microsoft Network Load Balancing Feature in both the Management Servers

After successful installation of NLB feature, open Network Load Balancing Manager from Administrative Tools and create NLB Cluster

Access SCOM Console with NLB Name SCOMConsole.kartik.com

Now, we see that SCOM Console is operational with the NLB Cluster Name

Test the Functionality:

To test this functionality, I have stopped the Data Access Service in Secondary Management Server. This SDK Service is the core for accessing the SCOM console

SCOM console is connected to SCOMConsole.kartik.com

Let us stop the SDK Service

We can see that the SCOM Console is still operational
