CLUSTRA DEMOS LINUX CLUSTER DATABASE

Linux received a huge boost in the enterprise market as Clustra Systems Inc, a leading provider of always-on technology for the 24x7 world, demonstrated its new Clustra DataCenter database appliance and the new 4.1 release of the Clustra Database at the LinuxWorld Conference & Expo. The Clustra DataCenter makes it easy to assemble a cluster of off-the-shelf Linux servers into a powerful, high-end database that rivals the performance of enterprise-class SMP servers at fraction of the cost while achieving continuous availability exceeding 99.999 percent uptime.

At LinuxWorld, Clustra will be publicly demonstrating the Clustra DataCenter for the first time, running on an ultra-high-density cluster from RLX Technologies, as well as the Clustra Database running on a heterogeneous cluster of computers from several manufacturers. Clustra offers the only Linux cluster database that delivers continuous availability, scales to hundreds of gigabytes, and runs on any Linux hardware -- including the new, ultra-high-density RLX ServerBlades and mixed clusters of commodity hardware -- without the need for complex, expensive SMP configurations.

"Clustra introduced the first Linux cluster database more than three years ago, and today we're previewing the Clustra DataCenter, the only self-managing, continuously available cluster database for Linux," said Dan Leighton, vice president of product marketing for Clustra Systems. "The DataCenter virtually installs itself, and is exciting for Linux users because now they can easily run non-stop, industrial-strength database applications on low-cost hardware."

The Clustra DataCenter is so easy to deploy that it can be installed and maintained by anyone. It is the first industrial-strength, zero-downtime cluster database appliance that runs on low-cost, off-the-shelf hardware. Release 4.1 of the Clustra Database includes a number of new features to further enhance operations and performance, and to make the database more flexible and easy to use.

According to IDC, Linux's market is expected to reach 38 percent by 2004 and is the fastest growing operating system in the market.

Expected to attract more than 20,000 attendees, LinuxWorld Conference & Expo, being held at San Francisco's Moscone Convention Center, is the ##1 event focused on Linux and Open Source solutions and is the world's largest marketplace for Linux products and services.
