Sybase, the enterprise infrastructure and integration software company, and Sun Microsystems have announced that Sybase's Adaptive Server Enterprise (ASE) 12.5 database will now work in conjunction with Solaris Server clusters.
Solaris Server clusters use Sun's Cluster 3.0 middleware and the SunPlex platform, which uses a mix of third-party hardware and software to create resilient server clusters that ensure high availability of applications.
"ASE has all the features that businesses need for successful e-business, it is low on cost and it runs on all platforms," says Julie Tomlinson, sales and marketing manager at Sybase SA. "It is also easy to use and provides the best return on investment."
The SunPlex platform is based on the Sun Enterprise, Sun Fire and Netra server lines, Sun's storage arrays, and its cluster interconnect hardware. The SunPlex software stack includes Solaris 8, Sun Cluster 3 and its application program interface (API), and the Sun Management Centre 3.0 console.
In addition to this is the Solstice DiskSuite management program from Sun and various programs from storage software and file system specialist Veritas Software, including Volume Manager, Volume Manager Cluster Functionality (formerly known as Cluster Volume Manager for Oracle Parallel Server), and the Veritas File System. Sun Cluster 3.0 supports up to eight nodes per cluster, and these nodes can be any of Sun's current UltraSPARCII or III servers. EMC Symmetrix disk arrays and Brocade Silkworm switches are also supported.
The Sun Cluster-SunPlex support of ASE 12.5 includes an active-active node clustering option. Rather than have one node be a fail-over node for another in the event of node failure, the active-active configuration makes one node an exact duplicate of the other node.
"In the event that the primary node fails, the secondary node, which was doing the same work already, continues processing as if nothing happened," says Tomlinson. "Such an active-active configuration can significantly reduce application downtimes."
