AppFabric 1.1 Caching: Seed node onloading is recommended for clusters with three or more cache hosts

This topic is intended to address a specific issue identified by a Best Practices Analyzer scan. You should apply the information in this topic only to computers that have had the AppFabric 1.1 Caching Best Practices Analyzer run against them and are experiencing the issue addressed by this topic. For more information about best practices and scans, see Best Practices Analyzer.

Issue

Seed node offloading is configured for a cluster with more than three hosts.

Impact

Cache operations might be negatively impacted.

Seed node onloading allows the cache cluster to remain available even if the cache cluster configuration store becomes temporarily inaccessible. If offloading is used, the entire cache cluster is unavailable any time the cache cluster configuration store is unreachable.

Resolution

Configure seed node onloading for this cache cluster.

For more information, see Set the Cluster Management Role and Lead Host Designations (AppFabric 1.1).
