IT architects needing a solution to deliver high availability and disaster recovery for mission-critical applications
About SIOS DataKeeper
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.

Windows Server Failover Clustering
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.
