If either server module fails, results from the remaining server are used while the failed server is restored to proper operation. Repairs require no special training: an IT staffer merely slides out the failed module, and inserts a new one. Best of all, the entire process -- from failure detection to repair -- takes place with no application disruption. As far as the operating system and applications are concerned, the system has been operating continuously!
Cluster solutions typically require a separate license for each server -- plus the clustering software. Then there's configuring scripts to handle application failover and fail-back. FlashServer HA appears as a single server to OS and application software, meaning only one copy of operating system and application software needs to be licensed.
