On-premises, in the Cloud and in hybrid cloud environments
SIOS DataKeeper Cluster Edition allows you to build a cluster using your choice of industry standard hardware and locally attached storage in a SANless configuration in a wide range of configurations. SIOS SANless clusters not only eliminate the cost, complexity and risk of a single point-of-failure from a SAN cluster, but also allow you to take advantage of the latest flash and SSD storage for performance and protection in a single cost-efficient solution. And you can add SIOS software to an existing hardware-based SAN cluster to achieve disaster recovery to a remote server in a recovery site or to the cloud.

Scale Out File Server (SOFS) and Storage Spaces Direct (S2D), two technologies offered in Microsoft Windows for disk sharing, cannot be used in a cluster to share disks across cloud regions and availability zones. This limits your configuration to one data center (availability zone) and if an outage occurs, access to application services may be lost.

In contrast, SIOS DataKeeper Cluster Edition simulates fully clustered shared storage and is capable of providing fully certified high-availability cluster protection across cloud regions and availability zones – giving you significantly greater protection against a wide range of failures.
