What We Do

Unparalleled Reliability

SIOS clustering software provides true “four nines” (99.99%) application high availability on premises, in the cloud and in hybrid cloud environments for both Windows and Linux environments. Use SIOS clustering software to create a traditional shared-storage cluster or use our powerful replication software to enable SANless clustering where shared storage is impractical or impossible.

High Availability 

SIOS protects essential applications such as SAP, SAP HANA, Oracle Database, MaxDB, and SQL Server from downtime and disasters.

Powerful Application Awareness

SIOS’s unique Application Recovery Kits (ARKs) bundled with SIOS LifeKeeper provide application-specific intelligence that automates and dramatically simplifies cluster configuration and ongoing management. Right-click convenience makes it easy to allocate resources and specify recovery policies with automatic and manual failover/failback options. These options also help simplify HA and DR testing and enable planned maintenance to be performed with minimal downtime.

ARK technology detects application-specific issues early and ensure failovers maintain application-specific best practices for fast recovery.


Disaster Recovery

SIOS provides advanced disaster recovery protection from local, sitewide and regional disasters. SIOS products failover across cloud Availability Zone, cloud regions, and across geographically separated on-prem datacenters for complete DR protection from local, site-wide and regional disasters.

Data Replication

SIOS DataKeeper Cluster Edition is a software add-on that integrates simply and seamlessly with Windows Server Failover Clustering (WSFC) to add performance-optimized host-based synchronous or asynchronous replication.

SANless Clusters

SIOS DataKeeper allows you to easily create a SANless cluster to achieve high availability and disaster recovery for your most important applications operating in the cloud, in virtualized environments such as VMware or on physical servers using only local storage. Use SIOS DataKeeper Cluster Edition software to protect your business-critical Windows environments, including Microsoft SQL ServerOracle, SharePoint, Lync, Dynamics, and Hyper-V from downtime and data loss in a physical, virtual, or cloud environment.

IT Resilience

IT resilience is the ability of an organization to maintain acceptable service levels when there is a disruption of business operations, critical processes, or IT ecosystem. High availability and disaster recovery are essential to IT resilience. Unlike OS-based HA solutions, SIOS offers HA solutions for all critical workloads, regardless of OS, platform, or application. SIOS enables companies to reduce cost and complexity by applying the same, consistent HA/DR protection throughout their organization.
