DataKeeper with High Availability – Cluster Edition Overview

SIOS DataKeeper is a highly optimized host-based replication solution which ensures your data is replicated as quickly and as efficiently as possible from your source server across the network to one or more target servers.

SIOS DataKeeper Cluster Edition is a highly optimized host-based replication solution which integrates seamlessly with Windows Failover Clustering. Windows Failover Clustering features, such as cross-subnet failover and tunable heartbeat parameters, make it possible for administrators to deploy geographically dispersed clusters. SIOS DataKeeper provides the data replication mechanism which extends Windows Server Failover Clustering, allowing administrators to take advantage of these advanced features to support high availability and disaster recovery configurations.

SIOS DataKeeper Cluster Edition is a separately licensed product. Once installed, a new storage resource type called DataKeeper Volume is available in Microsoft Windows Server Failover Clustering. This new SIOS DataKeeper Volume resource can be used in place of the traditional Physical Disk shared storage resource to enable geographically dispersed clusters.

Important Consideration: Prior to installing SIOS DataKeeper Cluster Edition, your Microsoft Windows Server Failover Cluster environment should be installed and created. This product requires a SIOS DataKeeper Cluster Edition License. SIOS DataKeeper resource type registration occurs 60 seconds after detecting a Failover Cluster configuration.


Some of the features include the following:

  • Synchronous or Asynchronous block level volume replication.
  • Built-in WAN optimization enabling SIOS DataKeeper to fully utilize a high speed/high latency network connection without the need for WAN accelerators.
  • Efficient compression algorithms optimizing use of available bandwidth.
  • Intuitive MMC 3.0 GUI.
