High Availabilty for Linux
LifeKeeper
SteelEye LifeKeeper for Linux offers application-focused data replication, high availability clustering and disaster recovery solutions. SteelEye LifeKeeper enables enterprises of all sizes to ensure continuous availability of business-critical applications, servers and data.
High Availability on Linux
SteelEye's LifeKeeper for Linux is a software application that ensures the continuous availability of applications by maintaining system uptime. LifeKeeper maintains the high availability of clustered Linux systems by monitoring system and application health, maintaining client connectivity and providing uninterrupted data access regardless of where clients reside - on the corporate Internet, intranet or extranet.
To enable automatic system and application recovery if the system goes down, LifeKeeper allows applications to failover to other servers in the cluster. This helps LifeKeeper minimize the risk of a single point of failure and allows Linux systems to meet the stringent availability requirements of mission-critical operations by creating a fault resilient environment.
Proactive Protection
With LifeKeeper, hardware component or application faults are detected in advance of a full system failure through multiple fault-detection mechanisms. LifeKeeper monitors Linux clusters using intelligent processes and multiple LAN heartbeats. By sending redundant signals between server nodes to determine system and application health, LifeKeeper confirms a system's status before taking action. This reduces the risk of a single point of failure and minimizes false failovers. LifeKeeper also limits unnecessary failovers by recovering failed applications, without a full failover to another server, if the hardware is still active.
