106 Part 3: Databases HFSQL Client/Server cluster HFSQL Cluster is an extension of the HFSQL Client/Server database model. In a database cluster, all HFSQL servers contain a copy of the databases and are synchronized in real time. • The read load can be balanced across multiple servers. • You can make changes to the physical configuration without interruptions on client computers. • If one of the servers crashes, the client is automatically redirected to an operating server.
