What We Do

SIOS software solutions make clusters easy use and easy to own. They add efficient replication for disaster protection to SAN-based environments and enable cluster protection in environments where shared storage clusters are impossible or impractical.

SAN and SANless Clusters

SIOS SAN and SANLess clustering software is an essential ingredient in any cluster solution that delivers the configuration flexibility to protect both Windows and Linux environments and any combination of physical, virtual, or cloud public, private, or cloud.


SIOS DataKeeper lets you add replication for disaster protection in a Windows environment. Use SIOS Protection Suite products to create a complete cluster and replication solution with advanced monitoring of the entire application stack.
