IT Briefcase: Enterprises Adopt SIOS Technology SANLess Clustering Software on Amazon Web Services for Cloud HA and DR

SAN MATEO, CA – May 11, 2015 – SIOS Technology Corp. (, maker of SAN and #SANLess clustering software products, today announced that leading enterprise companies are turning to its SANLess clustering software, SIOS DataKeeper Cluster Edition, to provide high availability (HA) and disaster recovery (DR) of critical data on business critical applications in Amazon Web Services cloud environments.  Some of these enterprises include Gulliver International, a Tokyo-based pre-owned car company; Epicure Selections, Canada’s leading direct sales company; andSpirent, a global leader in communications test and measurement.

“Business critical applications require high availability protection, regardless of where they are deployed,” said Jerry Melnick, COO, SIOS Technology.  “In the cloud, you need to protect applications from downtime just as you do in a physical server environment. However, traditional solutions, such as shared-storage clusters may not be practical or even possible in the cloud. With SIOS SANLess clustering software, enterprises are able to use traditional Windows Server Failover Clustering to provide high availability and disaster recovery protection for SQL Server and other enterprise applications in the cloud without the limitations of shared storage.”

Most cloud providers enable a measure of disaster protection by allowing enterprises to use multiple separate and redundant data centers or computing resources. However, they do not offer shared storage (i.e., a SAN), which is required to support traditional Microsoft Windows Server Failover Clustering (WSFC) for high availability. SANless software can be added to a WSFC to create a high availability cluster without the need for shared storage. With it, companies can quickly and easily run their business critical applications, such as SQL Server, SAP, Siebel Gateway, and others, in a cloud environment without sacrificing high availability protection.
