FalconStor Active-Active Failover

Automatic System Failover For Your Storage Infrastructure

NASI Storage Core with IPStor offers an active-active failover feature, which builds high availability into your storage architecture.

Eliminate single-point-of-failure within your storage architecture with redundant NASI Storage Core systems. If one storage manager experiences system failure, the active-active failover feature of IPStor will automatically detect it and transfer all processing functions to the working storage server, until the failed system is back up and running.

This active-active failover feature uses a more robust failure detection system. Many competing active failover system simply use a “ping”- or “heartbeat”-based detection of system failure, while the IPStor active-active failover meachnism utilizes self-monitoring and intelligent information gathering functionality to determine if a failure condition exists on the primary system.

Continuous operation in the planned or unplanned downtime of a NASI Storage Core appliance

Achieve 24x7 availiability by eliminating this potential point-of-failure. You can upgrade and update firmware, hardware and software at ease too, without interrupting your backup process.

Seamless integration into redundant architecture

Each NASI Storage Core server is completely indepedent of one another, and can be run in active-active mode to balance loads, which helps performance, and can switch to active-passive mode when one experiences downtime for failover in the event of systems failure, or planned downtime for upgrades and/or maintenance.

If this active-active failover module is combined with the FalconStor Synchronous Mirroring option, you can even provide high-availability to non-high-available single-port storage devices with the front-end high availability of this feature.

Stay platform-independent on multi-path drivers

With the IPStor active-active failover, customers don't need to deploy multi-path drivers at all of the host servers, which are available on limited operating systems, and can severely limit your potential choices of storage vendors if your business requires a high availabile storage configuration.

The IPStor active-active system failover solution Eliminates the need for expensive and proprietary multi-pathdrivers, by having the failover NASI Storage Core appliance simply by taking over the downed IPStor appliance’s World Wide Name (WWN) and identity.

This way, from the host server’s perspective, the downed IPStor appliance is still “up-and-running”, and all pending data transfers are simply delayed slightly. NASI Storage Core can also make use of multi-path drivers to defend against HBA or wire failures.
