Continuous business operations depend on reliable access to critical data and applications. This dependency means that high availability is essential to servers that power complex,
large-scale transactional applications or databases. Within data centers, it is essential to have a back-up plan should a server fail, to ensure no data is lost and that applications are available at all times. NEC ExpressCluster LAN is a high availability clustering solution that ensures application and data availability in local area networks. With full clustering capabilities and unique synchronous data mirroring technology, ExpressCluster LAN delivers reliable data protection at all times.
Synchronous Data Mirroring Technology Closes the Gap
Many products only offer asynchronous replication. If a failure happens before data can be copied, data will be lost. By contrast, NEC's proven synchronous data mirroring technology protects against both hardware and software failures, ensuring that critical data and applications are always available for quick recovery. Any time data is added or changed, the new data is automatically copied from the primary system to the standby system in real-time, so there is no gap during which data could be lost. Moreover, ExpressCluster LAN data mirroring is storage independent so no external storage system is needed to provide
data protection.
