Guidance for Using Network Load Balancing in System Center 2012 - Service Manager
Updated: January 17, 2012
Applies To: System Center 2012 - Service Manager Release Candidate
You can use network Load Balancing (NLB) in Windows Server 2008 to configure a pool of computers so that they take turns responding to requests. In System Center 2012 – Service Manager, the initial Service Manager management server that you deploy is the server that processes workflows. You can deploy additional management servers to provide failover for a failed initial management server and to provide load balancing for handling Service Manager console. For more information about Windows Server 2008 NLB, see the Network Load Balancing Deployment Guide. For more information about additional Service Manager management servers, see Deploying Additional Service Manager Management Servers.
As a minimum, you have to deploy an initial Service Manager management server—the management server that hosts the workflow processes—and at least one additional Service Manager management server. In an environment of this kind that consists of two Service Manager management servers, configure NLB to use both management servers, as shown in the following illustration.
If you deploy two or more additional Service Manager management servers, you can isolate the initial Service Manager management server from the NLB pool. This reduces the workload on the initial Service Manager management server, resulting in better workflow performance. It also load-balances all of the Service Manager consoles across the remaining Service Manager management servers. This scenario is shown in the following illustration.
