SIOS LifeKeeper for Linux

Protect Essential Linux Applications from Downtime and Disasters

SIOS LifeKeeper for Linux is a simple, cost-efficient clustering software that provides complete high availability (HA) and disaster recovery (DR) protection for SAP, SAP S/4HANAOracle, MaxDB, and other essential applications. Applications protected by LifeKeeper keep running through a wide range of fault, failures, and local, site-wide, and regional disasters, enabling you to meet your availability SLAs with ease.

SIOS LifeKeeper supports all major Linux distributions, including Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Rocky Linux, and Oracle Linux and accommodates a wide range of storage architectures.

Continuous Monitoring of the Entire Linux Application Stack

Unlike other clustering solutions that only monitor server operation, SIOS LifeKeeper monitors and protects against issues in the entire application environment – server, storage, operating system, network, database, and application.

Complete Application-Aware Protection

Powerful application recovery kits (ARK) enable SIOS LifeKeeper to ensure fast, safe recovery or failover of complex applications and databases. When a problem is detected, SIOS LifeKeeper automatically manages the response according to one of three preselected options – alerting the administrator, restarting the application, and/or managing a complete failover to another node. ARKs ensure application operations continues on secondary cluster node(s) quickly and seamlessly.

Web Management Console Designed for Easy Management

The SIOS LifeKeeper Web Management Console was designed to take the complexity out of implementing and managing high availability clusters.

  • Information cues provide self-help for all functionality
  • Setup progress tracking speeds implementation
  • Easy Installation – No need for additional installations or add-ons
  • Simplified firewall management – access on only 2 TCP ports
  • Responsive design enables use with tablets and smart phones

SIOS LifeKeeper supports a wide range of options for customers who need advanced security, including:

  • LifeKeeper can be run in an environment with IMDS2 (Instance Metadata Service) in AWS. The latest version of IMDS2 provides enhanced protection for programs accessing sensitive instance metadata including cloud instance ID, IP address, and the security group to which it belongs.
  • Security-Enhanced Linux (SELinux) in all three modes: enforcing, security, and disabled. SELinux provides access control to the Linux kernel as required by the U.S. National Security Agency (NSA).

Wizard-Driven Setup Simplifies Linux Clustering

SIOS LifeKeeper software provides an intuitive setup wizard that lets you setup your Linux cluster in minutes not hours in a wide range of configurations.

Complete Configuration Flexibility

Build a traditional shared-storage cluster or use SIOS software to synchronize local storage in a SANless cluster configuration. SIOS LifeKeeper supports a wide array of storage devices, including direct-attached storage, iSCSI, Fibre Channel and more. SIOS LifeKeeper also gives you complete configuration flexibility, including Physical-to-Physical (P2P), Physical-to-Virtual (P2V) and Virtual-to-Virtual (V2V) clusters.

SIOS Protection Suite

SIOS LifeKeeper comes with SIOS DataKeeper, and multiple Application Recovery Kits (ARKs) in a bundle called SIOS Protection Suite.

SANless Clustering for Performance or Cloud

Use SIOS software to synchronize local storage on all cluster nodes for SANless failover clustering protection where shared storage solutions are impractical or impossible, such as in a cloud, a virtual environment, a high-performance SSD storage or a hybrid storage environment. Use SIOS clustering software to protect critical applications in AWS, Azure or the Google Cloud Platform.
