High Availability Operation
In High Availability (HA) operation, Stratus Redundant Linux automatically detects, isolates, and handles most hardware faults, thereby keeping your applications running. With HA remote-support technology, the software notifies the Stratus support center of various issues, indicating the type of fault and its exact location. This combination of automatic fault detection, isolation, and remote-support technologies ensures speedy access to expert support technicians and rapid problem resolution.
HA operation offers basic failover and recovery, with some faults requiring an (automatic) VM reboot for recovery, and return to HA operation:
- Eliminates downtime for many, but not all, CPU, memory, I/O, or other physical machine (PM) failures.
- Handles failures without IT intervention.
- Provides continuous, active validation of all components.
- Assures redundancy and recovery at all times.
HA is suitable for applications that can tolerate occasional interruptions of a few minutes.
