Tuning Failover Cluster Network Thresholds


Hi all,

Some time ago, I had an issue into Cluster environment, Windows 2008 R2, which caused some impact in the production environment. After investigate the root cause of that problem, I find out, network was the cause for failover between nodes. In some case, when we have overloaded infrastructure, or some issue into network, which cannot be resolved for us, we ourselves can create a temporary workaround. The task performed was increasing the Heartbeat threshold, and after the network problem issue resolved, I changed back for the default values. I found two web sites that helped me to know, the default and maximum values.

That’s all. 🙂
