Sun, AT&T, Nortel Help Ensure On-time Delivery for Chicago Tribune

3/19/2004 - The advanced technology used by the Chicago Tribune is about to receive an upgrade from Sun Microsystems [NASDAQ: SUNW], AT&T [NYSE: T] and Nortel Networks* [NYSE/TSX: NT] to help ensure continued, on-time delivery for millions of its readers and advertisers.

Chicago Tribune Company, a subsidiary of Tribune Company, [NYSE:TRB], has selected Sun Microsystems, Inc., AT&T and Nortel Networks to deploy an enterprise continuity solution that will replace various servers and some mainframe equipment, providing greater security and reliability while reducing costs and complexity. The solution will link two Chicago sites, ensuring reliable access and real-time "mirroring" of data and applications.

Leveraging the alliance of three leaders in the networking and technology industry, the Chicago Tribune will be able to consolidate and protect its business-critical applications, including the production of the newspaper's editorial and advertising content, customer service and billing, warehouse management, production planning and management, and customer data. The new solution is expected to bring a high level of reliability and system availability.

"As our customers increasingly rely on the technology that supports their business strategies, Sun has continued to develop and deliver solutions that provide optimal performance, increased system availability and improved response times," said Scott McNealy, president, chairman and chief executive officer, Sun Microsystems. "Our Solaris Operating System offers the reliability, simplicity and affordability required by companies such as the Tribune."

"With this project Chicago Tribune is responding to changing market demands and is leading the media industry in the use of advanced technology solutions," said Darko Dejanovic, vice president and chief technology officer, Chicago Tribune Company and Tribune Publishing Company, which also owns the Los Angeles Times, New York Newsday and 11 other leading daily newspapers. "We're taking a leading position to further ensure uninterrupted service to our customers, while decreasing costs and improving operational efficiencies." Chicago Tribune Company will be one of the first companies to deploy this innovative solution to lower costs, mitigate risk of business disruption and maintain access to mission-critical applications.

"The integrated AT&T Ultravailable[R] Computing business continuity solution was a perfect fit for the Tribune Publishing Group because of the high levels of reliability and flexibility it offers," said Pat Traynor, vice president, Network Integration, AT&T. "As a leader in Network Integration, we have formed alliances with best-in-class providers, including Sun and Nortel Networks, to leverage their specialist knowledge making it easy for customers to get a one-stop solution for their business continuity and complex networking needs."

"The joint enterprise continuity solution truly represents an industry breakthrough in that it offers unprecedented levels of business continuity," said Brian McFadden, president, Optical Networks, Nortel Networks. "This new computing model allows enterprises of all sizes to break through barriers to productivity and leverage the power of optics to extend their computing and storage applications over industry-leading distances and ensure geographic resiliency."

The Technology
Chicago Tribune's new infrastructure will consist of two Sun Fire 15K servers running Sun Cluster 3.1 software and Sun's Solaris 9 Operating System. The solution has the capability of spanning more than 400 kilometers and has the potential to link into Sun's N1 Grid software.

Key to the solution is AT&T Ultravailable® Computing, a fully managed service that integrates a private, high-speed, highly reliable metropolitan area network with Sun's systems to help ensure uninterrupted access to critical data and applications. The network leverages Sun Cluster software and the DWDM-based Nortel Networks OPTera Metro 5200 Multiservice Platform.

Traditionally, clustered systems have been able to provide high levels of systems availability, as long as the complete cluster system was located close together, which was either prohibitively expensive or resulted in the servers being unable to operate across remote sites.

Customers looking for the reassurance offered by multiple site operations traditionally used an "active-passive" configuration, meaning one server was in operation while one would be on standby. It would take some time for the second server to come online. However, by leveraging the Sun, AT&T and Nortel Networks alliance, the Chicago Tribune Company is able to cost-effectively deploy an "active-active" distance clustering approach, providing it with a more efficient use of resources, and allowing it to quickly restore operations in the event of a disaster at the primary site.
