"Web and network managers can now create and maintain high-availability server clusters at a breakthrough price point."

"PolyServe today announced Understudy, a high-availability server clustering software suite for e-business. This new software product provides: sophisticated process monitoring, server failover, network administrator notification, content replication/synchronization and reintegration."

"Understudy monitors IP services including HTTP, SMTP, TCP and FTP. Upon detection of a failure, Understudy removes the failed server from the cluster and fails-over to the secondary backup host. Understudy then generates a network administrator notification via email and/or page. Understudy also includes the first commercial application of InterMezzoTM, state-of-the-art distributed file system software developed by Stelias Computing. Via InterMezzo, Understudy provides sophisticated data replication and content distribution. InterMezzo ensures that all servers in the cluster always have the most up-to-date version of every relevant file. Thus, if a server fails and drops out of the cluster, all file activity from that server prior to failover will have been accurately replicated on the other servers in the cluster, enabling uninterrupted service. Upon recovery, a failed server can be re-integrated into the cluster where it will be immediately and automatically updated with all relevant file changes."
