About

OpenText Availability continuously replicates physical, virtual, and cloud systems at the byte level, capturing real-time changes with a Recovery Point Objective of seconds, and maintains duplicated Windows and Linux servers at secondary locations for near-zero downtime. In the event of an outage, it offers automated or on-demand failover with integrated heartbeat monitoring and DNS management, followed by seamless failback when systems are restored. Data is secured with AES 256-bit encryption in flight, while three tiers of compression and bandwidth-throttling options minimize network impact. An extensive API allows integration with other applications, and built-in alerting, reporting, and non-disruptive failover testing ensure administrators can monitor health, troubleshoot, and validate disaster-recovery plans without affecting production workloads. OpenText Availability supports any hypervisor, including VMware ESXi/vSphere and Microsoft Hyper-V, and any major cloud platform.

About

Failover Clustering in Windows Server (and Azure Local) enables a group of independent servers to work together to improve availability and scalability for clustered roles (formerly known as clustered applications and services). These nodes are interconnected via hardware and software, and if one node fails, another assumes its roles through an automated failover process. Clustered roles are actively monitored and, if they stop functioning, are restarted or migrated to maintain service continuity. The feature also supports Cluster Shared Volumes (CSVs), which provide a unified, distributed namespace and consistent shared storage access across nodes, reducing service disruptions. Typical uses include high‑availability file shares, SQL Server instances, and Hyper‑V virtual machines. Failover Clustering is supported on Windows Server 2016, 2019, 2022, and 2025, and in Azure Local environments.
