Cluster Computing:

QLUSTERS PARTNERS W/ RACKABLE TO PROVIDE UTILITY COMPUTING

Qlusters, Inc. announced a strategic partnership with Rackable Systems to integrate and co-market a comprehensive enterprise management solution. The joint solution is based on Qlusters' ClusterFrame enterprise cluster management software and Rackable Systems' rack-mount cluster servers. The combined utility computing enterprise solution targets large-scale Linux- based data centers.

ClusterFrame minimizes IT costs by optimizing the operation of Linux clusters deployed on commodity hardware. The three components of ClusterFrame address three vital requirements of the enterprise data center: ClusterFrame QRM (Qlusters Resource Manager) provides policy-based management; ClusterFrame XHA (Xtreme High Availability) adds instant hardware and application fail- over; ClusterFrame SSI (Single System Image) completes the package with transparent hardware virtualization.

Qlusters and Rackable Systems will exhibit their combined solution at the upcoming Linux on Wall Street show on April 28. Held at the Roosevelt hotel in Manhattan, Linux on Wall Street focuses on financial market applications for open source, grid and utility computing. "Linux installations are expected to grow at an annual rate of 22% in the North American securities market over 2003 - 2006," according to Senior Analyst Dushyant Shahrawat at TowerGroup.

"Qlusters is forging key strategic partnerships within the exploding utility computing market." said Dave Martin, CEO and Chairman of Qlusters. "Partnering with Rackable Systems provides our IT customers a tightly integrated utility computing solution."

Utility Computing is the ability to provide computing as a ubiquitous service, adapting to changing user and application needs. Enterprise cluster management is an integral part of utility computing, an emerging paradigm for IT systems management. With ClusterFrame, Qlusters harnesses computing resources to provide a manageable, dynamically scalable and highly available data center for both hardware and applications.
