It was originally designed and developed by
AT&T Bell Labs in 1992 to ensure high availability of their worldwide voice network system running on Unix-based Star Servers. After AT&T divested the LifeKeeper division to
NCR, SteelEye acquired the technology in 1999. SteelEye was later renamed

Description
High availability clusters (HAC) improve application ''availability'' by ''failing'' them over or ''switching'' them over in a group of systems—as opposed to
High Performance Clusters, which improve application ''performance'' by running them on multiple systems simultaneously. SIOS LifeKeeper provides continuous monitoring of the entire application stack and will recover a service or application locally or on another cluster node at the same site or another geographic location. It supports all major Linux distributions and accommodates a wide range of storage architecture. SIOS clustering software synchronizes local storage on all cluster nodes creating a cluster in a cloud where shared storage is not available. SIOS LifeKeeper is SAP-certified for SAP NetWeaver and SAP S/4HANA to monitor the critical services and automatically apply SAP best practices for nonstop operation of critical SAP environments.
