SteelEye Targets Complex High-Availability, Disaster Recovery Needs

SteelEye’s new DataKeeper 7.1 and DataKeeper Cluster Edition 7.1 help customers with more complicated high-availability and disaster recovery requirements than in the past to ensure the continued availability of their data, said Dave Bermingham, director of product management for the San Mateo, Calif.-based storage vendor.

DataKeeper is a host-based volume replication clustering solution and prior to version 7.1 was limited to two nodes and would not work with existing clusters, Bermingham said.

The new version allows customers to extend their existing Microsoft and Linux clusters to remote sites for disaster recovery and to build a completely new second cluster in a remote site for complete failover, he said.

“With 7.1, partners can now go into environments where the customer has, say, an existing three-node SQL server cluster connected to a SAN who wants to add high-availability and replicate over multiple sites,” he said. “Now they can add a fourth node at a remote site and have remote failover.”

DataKeeper 7.1 and DataKeeper Cluster Edition 7.1 mainly target Microsoft applications such as SQL and Exchange, or any application that works with Microsoft Cluster Server, Bermingham said. It also plugs into Microsoft’s Hyper-V virtualization technology to provide high availability and disaster recovery using any type of storage including server-attached storage, he said.

Also new is the ability to support replication over three or more nodes for increased data availability. This also allows data to be replicated from one server to another in the same data center and remotely to a third server to provide both local and remote copies of data, he said.

About 80 percent of SteelEye’s business is through indirect sales channels.
