SIOS Protection Suite/LifeKeeper for Linux – Integrated Components
SIOS Protection Suite includes the following software components to protect an organization’s mission-critical systems.
SIOS LifeKeeper provides a complete fault-resilient software solution that enables high availability for servers, file systems, applications, and processes. LifeKeeper does not require any customized, fault-tolerant hardware. LifeKeeper simply requires two or more systems to be grouped in a network and site-specific configuration data is then created to provide automatic fault detection and recovery.
In the case of a failure, LifeKeeper migrates protected resources from the failed server to a designated standby server. Users experience a brief interruption during the actual switchover. However, LifeKeeper restores operations on the standby server without operator intervention.
SIOS DataKeeper provides an integrated data replication capability for LifeKeeper environments. This feature enables LifeKeeper resources to operate in shared and non-shared storage environments.
Application Recovery Kits (ARKs)
Application Recovery Kits (ARKs) include tools and utilities that allow LifeKeeper to manage and control a specific application or service. When an ARK is installed for a specific application, LifeKeeper is able to monitor the health of the application and automatically recover the application if it fails. These Recovery Kits are non-intrusive and require no changes within the application in order for it to be protected by LifeKeeper.
There is a comprehensive library of ‘off-the-shelf’ Application Recovery Kits available as part of the SIOS Protection Suite portfolio. The types and quantity of ARKs supplied vary based on the edition of SIOS Protection Suite purchased.
