Sybase gets into the cluster-database game (InfoWorld)

San Francisco - Sybase Tuesday launched its strike in the cluster-database market, releasing Adaptive Server Enterprise Cluster Edition to compete with the likes of Oracles Real Application Clusters.

Sybases offering is aimed at IT shops that require high availability from their datacenters. It uses shared-disk clustering, where a number of ASE server instances is grouped into a cluster seen as a single system managing the same set of data. This allows application workloads to be balanced among the instances. The software automatically migrates connections if a node fails, according to the company.

Noel Yuhanna, a Forrester Research analyst covering database technologies, said Sybase has made a wise move.

"Theyve realized they need to innovate to stay competitive and theyre doing that," he said. "I think its a good move and makes them comparable in certain situations with Oracle RAC."

While most companies employ some type of failover technology in their data centers, it may take effect in minutes, not seconds, Yuhanna said. "Companies who want it to happen really fast, thats when shared-disk clustering can really help," he said.

"Its only about five to 10 percent of the applications in an organization that would really need that up-to-the second [performance]," Yuhanna added.

Sybase hasnt necessarily surpassed Oracles capabilities, according to Yuhanna. Its new product might be more suitable for "smaller environments, or those that are only focused around Linux and Solaris," he said, adding that word hasnt yet circled back from customers regarding the products performance.

David Jonker, senior product marketing manager in the ASE group at Sybase, said the company worked with 12 large companies on a technology preview version of the software. He declined to name them, and said none had agreed to speak to the media.

ASE Cluster Edition is compatible with systems running Red Hat Enterprise Linux 4 and 5 (x86_64); Solaris 9 and 10 on Sparc (64-bit); and SUSE Linux 9 and 10 (x86_64). Sybase did not release pricing information.
