Apart from managing a distributed caching environment, PowerCache also provides a high-reliability, fault-tolerant configuration as well. New servers can be hot-added and hot-removed from a PowerCache infrastructure. Additionally, in the case of a network failure, servers running the PowerCache caching provider can continue to operate in stand-alone mode until network connectivity is restored. Once network conectivity is restored, the web servers will automatically reconnect to the PowerCache SyncServer and then synchronize their own cache with the cache of all of the other servers in the cluster.
