LifeKeeper for Linux is SteelEye Technology's easy, flexible, and fast solution for high availability.

Today many businesses struggle to balance the need for systems that can support mission-critical applications and pressures to reduce total cost of ownership for IT infrastructure. SteelEye's Linux data protection solutions enable businesses to get the best of both worlds - Linux cluster high availability.

Linux provides a high performance, reliable, open-source solution and its low cost makes it the platform of choice for companies that are targeting the new Web economy. SteelEye enhances the stability and power of Linux with LifeKeeper - a commercially proven, high availability Linux data protection software solution that provides fault-resilience to support mission-critical applications.

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 Linux cluster 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.

Fault Resilience

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.

Proactive Protection

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.
