SANTA CLARA, CA -- Sun Microsystems, Inc. today announced that it has completed the acquisition of Clustra Systems, Inc., a leading developer of high-availability clustering technology that enables continuous real-time computing. The Clustra technology will enable multiple software products from Sun, beginning with the iPlanet Application Server, and is expected to extend the high availability of the Sun Open Net Environment (Sun ONE) solution by delivering a unified, self-repairing, massively scalable web services software platform. "The web is already mission-critical for many organizations, and with the acquisition of Clustra, we're taking an important step to dramatically extend the availability and scalability of Sun's platform for services on demand," said Mark Tolliver, Executive Vice President and General Manager, iPlanet Products. "Clustra's always-on technology will play a key role within the Sun ONE solution by extending the reliability and availability of the iPlanet Application Server. Clustra brings world-class software people and technology to Sun, and we are excited to have them join us." "This technology is a perfect match to help Sun achieve its three big bets: massive scalability, continuous availability, and an integrated software stack" said Gary Ebersole, Senior Director at Sun Microsystems and former CEO of Clustra. "We are very pleased to be joining Sun and are looking forward to driving innovation in the area of continuous system uptime for the company." Clustra's unique architecture, designed with application servers and services on demand in mind, builds availability and automatic self-repair into the core underlying design. By combining mirrored storage with redundant software processes, Clustra enhances service delivery during failure events and maintenance operations, allowing companies to easily grow and manage their web services environments without downtime. As part of the iPlanet Application Server, these high availability and scalability capabilities will deliver the unique session state management capabilities to approach continuous operation under fail-over circumstances. Clustra Systems was privately held, and headquartered in Oakland, California. Financial details of the acquisition were not disclosed. The Clustra acquisition demonstrates Sun's growing investment in the company's software product portfolio. Sun has taken a strategic approach to its acquisition activity by making deals that enhance and reinforce Sun's product, technology and open standards position in the industry. Recent acquisitions include HighGround Systems for storage software, LSC, for file system software, NetBeans for open source tools and Cobalt systems for Internet server appliances.
