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

SIOS DataKeeper is a host‑based, block‑level replication solution that delivers real‑time, synchronous or asynchronous redundancy for Windows Server environments, integrating seamlessly with Windows Server Failover Clustering (WSFC). It enables "SANless" clusters—eliminating dependency on shared‑storage arrays—by replicating data across local, virtual, or cloud servers, including VMware, Hyper‑V, AWS, Azure, and Google Cloud Platform, while offering optimized performance without requiring hardware accelerators or compression devices. Once installed, it provides a new SIOS DataKeeper Volume resource in WSFC, supporting geographically dispersed clusters via cross‑subnet failover and configurable heartbeat parameters. Built-in WAN optimization and efficient compression maximize bandwidth use over local and wide‑area networks.
