ExpressCluster is a scalable High Availability (HA) clustering solution. It can cluster up to 32 nodes and supports your IT system environment with host of flexible functions.

ExpressCluster is well fit with complex LAN and WAN environment, comprising of physical and virtual servers as well as multiple cluster configuration.

Almost any application/database running on Windows or Linux platforms can be protected and covered by ExpressCluster.
ExpressCluster is designed to support latest technologies. ExpressCluster is one of the first software to demonstrate clustering on Microsoft Hyper-V Platform. It also supports other standard virtualization platforms like VMWare Server/ESX and Xen.

ExpressCluster is the first clustering software to implement Hybrid Clustering, i.e. mirroring of data in a shared disk for both LAN and WAN Environments.

In order to respond to the environmental issues, ExpressCluster also provides power management functions to enable Green IT systems.
 Product Overview
NEC ExpressCluster is an integrated High Availability (HA) and Disaster Recovery (DR) software solution that addresses fast recovery and continuous protection needs of business critical applications and data.

ExpressCluster minimizes system outages due to sudden events like hardware, software and site failures or planned outages due to hardware, software and site maintenance.

ExpressCluster enables easy to deploy and cost effective continuity solutions for critical systems running industry standard applications, OS, and virtualization platforms With ease of deployment and management as key design elements, NEC delivers a significantly reduced total cost of ownership when compared to alternative solutions.
 Data Protection
Robust disk mirroring capabilities including both synchronous and asynchronous mirroring modes. With flexible support for multiple configurations, ExpressCluster enables up to 99.99% data availability.
  • Ensuring data on both servers always synchronized and protected.
  • Multiple split-brain detection and resolution techniques to maintain data integrity.
  • Fast data mirroring technology replicating only updated blocks
 High Availability (HA)
ExpressCluster ensures High Availability (HA) to application and data in local area networks (LAN).
With full clustering capabilities and unique synchronous data mirroring technology, it delivers reliable data protection at all times.
  • Fast automated recovery against hardware and software failures minimizes unplanned downtime.
  • Support for low cost standard applications and hardware minimizes total cost of ownership.
  • Easy application and data workload migration minimizes planned downtime.
 Disaster Recovery (DR)
Powerful disaster recovery capabilities 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.
  • Fast application recovery with virtually no data loss maximizes business continuity.
  • Unified disaster recovery solution for multiple application systems magnifies manageability.
  • Support for standard application, OS, server, storage and network minimizes total cost of ownership (TCO).
