Native SQL server failover clustering in the Amazon Cloud

New SteelEye DataKeeper Cloud Edition delivers complete data protection, high availability, performance and cost savings in Amazon EC2 environments with no SAN required.

SIOS Technology has announced the launch of SteelEye DataKeeper Cloud Edition, the first and only high-performance data replication solution to deliver unmatched, real-time SQL Server data protection in Amazon EC2 environments. A joint effort with Amazon, SteelEye Datakeeper Cloud Edition is the only solution to enable native SQL Server failover clustering in the Amazon Cloud without requiring shared storage (SANs).


SteelEye DataKeeper Cloud Edition enables easy deployment of high-availability systems in the cloud. As a result, companies can now take advantage of the flexibility and scalability of Amazon Web Service (AWS) cloud deployments, enabling Amazon customers to achieve optimal performance while lowering total cost of ownership.


“SIOS understands the inhibitors that prevent users from taking advantage of disruptive technologies like the cloud,” said Celia Catani, SIOS vice president of America sales. “Through our partnership with Amazon and the introduction of SteelEye DataKeeper Cloud Edition, not only are we the only company to make opportunities like failover clustering in the Amazon Cloud possible, but we make it easy for customers to reap the benefits of a cluster, without an expensive SAN.”

Because SteelEye DataKeeper Cloud Edition eliminates a cluster's requirement for shared storage, it reduces cost, complexity and the potential single point of failure in clustering architectures. In the Amazon Cloud, failover of SQL instances is enabled within and across EC2 availability zones, and real-time copies of data are kept in sync across multiple nodes. As a result, users benefit from maximum uptime and complete data protection with zero data loss, at a fraction of the cost of a SAN-based solution.

SIOS’ SteelEye DataKeeper utilises block-level replication for highly efficient and optimised performance. This enables DataKeeper Cloud Edition to achieve over 90 percent bandwidth utilisation and offers nine levels of integrated compression and bandwidth throttling. The new solution can be easily integrated into Microsoft ecosystems without proprietary file systems or technologies and is fully integrated with Microsoft Cluster Services (MSCS) and Windows Server Failover Clustering (WSFC). SteelEye DataKeeper Cloud Edition provides full support for Standard or Enterprise Editions of SQL Server 2005, 2008, 2008R2 and 2012.
