SIOS General Availability of Protection Suite for Linux V.9.5.2 Clustering Software

Features enhanced HA for SAP S/4HANA in cloud environments, also Protection Suite for Windows V.8.8.0 with improved HA for critical Windows applications in cloud.

SIOS Technology Corp. announced the GA release of Protection Suite for Linux version 9.5.2 clustering software, featuring enhanced automation and application failover orchestration that makes creating and managing HA clusters in complex SAP S/4HANA environments easier and more reliable for enterprises.


The company also recently released Protection Suite for Windows version 8.8.0 clustering software featuring innovations designed to make HA clustering in the cloud faster and easier.

For many IT managers, creating a failover cluster to protect critical applications is a complex, time consuming process, often with unreliable results. Protection Suite clustering solutions deliver HA and DR protection while eliminating this complexity and uncertainty by automating manual tasks and providing application-specific failover orchestration.

The latest releases are focused on making clustering in public clouds – Microsoft Azure, AWS, and Google Cloud Platform (GCP) – faster and easier,” said Masahiro Arai, COO. “These new features give enterprises additional confidence that the HA they have always trusted from SIOS can be achieved in the public clouds.

Features and capabilities in SIOS Protection Suite for Linux 9.5.2, include:

  • Enhanced, support for HA in GCP. Enhancements include SIOS Internal Load Balancer tool designed to orchestrate efficient IP management during switchovers and failovers.

  • All functions of GUI are available via CLI. Allowing customers who use products such as Ansible the ability to automate their interactions with SIOS LifeKeeper.

  • Near-Zero Downtime for switchover during planned maintenance. Supports a new HANA ‘Takeover with Handshake’ feature enabling near-zero downtime time during switchovers by eliminating the potentially time-consuming process of shutting down the primary HANA server database. As a result, customers can perform planned maintenance without disrupting ongoing service to end-users.

  • Empowering customers by making SAP logging easier to use. Updates existing messages to make error messages and logs clearer and easier for customers to understand and act on.

Also in version 8.8.0:

  • DR protection for critical applications on AWS EC2. Application recovery kits enable failover across availability zones for reliable HA failover and protection from site-wide and regional disasters. Enhanced configuration flexibility – with new IP Recovery Kit enabling the use of cluster nodes in multiple availability zones.

  • Enhanced support for Microsoft Azure Cloud internal load balancer for fast, reliable cluster failovers.

Protection Suite for Linux and SIOS Protection Suite for Windows, include:

  • LifeKeeper – Flexible failover clustering software that monitors the entire application stack and orchestrates application-aware failover.

  • DataKeeper – Fast, efficient host-based, block level data replication for mirroring local storage in a SANless cluster configuration or replicating to remote locations or cloud for DR.

  • Application Recovery Kits (ARKs) – Extensions to LifeKeeper that integrate with applications to provide intelligent methods for simplifying setup, automating manual tasks and handling diverse application recovery events. They detect application level failures and ensure applications-specific best practices are maintained throughout the failover process.

DataKeeper Cluster Edition, includes:

  • Maintenance updates for our replication software which enables SANless clustering in conjunction with Windows Server Failover Clustering.

Protection Suite for Linux version 9.5.2 is available.
