Neverfail for Exchange replicates the complete application environment to a secondary server to ensure no single point of failure. Neverfail for Exchange constantly onitors your Exchange service and underlying system and proactively manages application or component failures. If a problem occurs, Neverfail for Exchange can either fix the problem or switch-over to the secondary system. In the event of a major system failure, Neverfail for Exchange will immediately detect the absence of the primary server, will failover, and restart Exchange on the secondary server, continuing service provision without impacting end-users.
Comprehensive failure detection:
- Monitors operating system, hardware, data (file system), network and Exchange application
- Heartbeat between systems to ensure system & network integrity and rapid fault detection
- Monitors key email services (inc. POP3, IMAP, SMTP) as well as Exchange
Replicates complete Exchange environment:
- Captures logical I/Os and asynchronously replicates data to secondary server
- Replicates Registry information (including active directory settings)
- Verifies data contents are same on both servers
- Dedicated Neverfail Channel for robust and high performance server to server communications
Dynamic Recovery:
- Repairs failed services and applications to keep the Exchange service up and running
- For more serious problems, can restart Exchange or switchover to secondary server

- Simple automatic switchback to the primary
- Allows for maintenance and upgrades to take place while secondary runs Exchange
Failover
- Immediate transfer of control to secondary server in the event of a major failure on the primary
- Failover heartbeat can be run over a shared or dedicated network with single of dual channels
Switchback
- Seamlessly switchback after failover to normal application state
- Provides complete operational control after failover
Operational Benefits
- Easy to install - installation can be completed simply by IT staff with minimal downtime of your existing Exchange server
- Works across dissimilar hardware - secondary server can be dissimilar to primary
- Does not require specialist software - works with your existing Exchange software and at the logical I/O level so does not need clustering versions of Exchange or Windows.
- Uses standard networking technologies - servers can be physically separated for site protection.
- Replicates data - does not require shared storage infrastructure but maintains exact copy for greater availability and robustness. Only replicates changes to the data.
- Drastically reduces downtime for ongoing maintenance - Primary server can be upgraded and maintained while secondary server provides service. Primary server resumes service and changed data is automatically copied back.
