Introduction
In this blog post, we’ll show you how to configure high availability for the Software Update Point (SUP) in SCCM. This setup ensures that patching continues even if your primary SUP fails.
How SUP Failover Works in SCCM
When the primary SUP is unavailable, SCCM clients automatically connect to the secondary SUP for software updates. However, setting up a secondary SUP requires careful planning and configuration.
Adding a Secondary Software Update Point
To add a secondary SUP, follow these steps:
- Install the SUP role on an additional server.
- Configure WSUS synchronization.
- Verify clients can fail over to the secondary SUP.
Testing SUP Failover in a Lab Environment
To test SUP failover, temporarily disable the primary SUP and monitor client connections using SCCM logs or WUAHandler.log.
Conclusion
Configuring high availability for your SCCM Software Update Point is crucial for maintaining continuous patching in your organization. If you’re looking to master SCCM, check out our Microsoft MECM Training.
