SANmelody^TM software converts PC servers into cost-effective expansion disk servers. Their added capacity appears as additional internal drives to disk-starved servers on LANs or SANs. Advanced options include point-in-time snapshots, auto failover across redundant disk servers, auto provisioning of disk space and long-distance asynchronous replication over IP WANs. These functions are host-independent and operate without occupying resources on the application servers.
