ExpressCluster WAN is a powerful disaster recovery solution for business critical transactional applications and data. It ensures near-instant recovery after system failure for full data protection,
even over standard T1 WAN spanning hundreds of miles. Unlike other solutions, ExpressCluster WAN dramatically simplifies the backup server recovery process thus reducing maintenance and
operational costs. With ExpressCluster WAN's intuitive GUI and remote management capabilities, administrators benefit from streamlined cluster control and improved visibility. Enhanced
monitoring agents for databases, web servers and network services are also available. By simplifying deployment and management of clustering solutions, NEC's ExpressCluster WAN
significantly reduces total cost of ownership while dramatically improving critical application and data availability.
TRANSPARENT PROTECTION FOR APPLICATIONS AND DATA
ExpressCluster WAN provides protection for all standard applications and data. Standard applications such as databases, web severs, and ERP server applications are supported without
requiring source code changes. Standard data repositories such as file and databases are also supported without requiring data format changes.
ExpressCluster WAN recovers all data committed to disk without loss in case of a site outage. Using either a periodic network request or heartbeat signal, it automatically executes failover procedures if a server on the network fails to receive a signal from another server. The backup system takes over all application processes and resources, so that business critical applications and data are recovered within minutes, instead of hours or days. Once a failed server is detected and repaired, the system
