LifeKeeper provides fault resilience for Linux cluster environments by enabling other servers in a cluster to take over for failed servers or failed applications. Total cost of ownership is reduced, because LifeKeeper supports an active-active and N+1 server configurations. These models eliminate the need for extra servers dedicated for hot backup and allow clients and applications to failover to other production servers in the cluster.
With LifeKeeper, hardware component or application faults are detected in advance of a full system failure through multiple fault-detection mechanisms. LifeKeeper provides Linux data protection by monitoring 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.
