Tandem Implements Enterprise Windows NT Strategy with New, Market-Leading Clustered Servers; First Product in Family of Clustered Servers Brings Tandem Fundamentals of High Availability and Manageability.

CUPERTINO, Calif.--(BUSINESS WIRE)--Aug. 13, 1997--Tandem Computers Incorporated, an industry leader in business-critical computing, today announced a major milestone in its strategy to lead the market in clustered Windows NT(R) Server systems.

The company introduced the CS150 ("CS" for Clustered ServerNet(TM)-enabled) as the first product in a family of clustered servers to be delivered in the coming months.

The new CS150 and subsequent clustered servers represent Tandem's commitment to extend traditional Tandem(R) fundamentals of high availability and scalability from its NonStop(R) Himalaya(R) platform to the open, industry-standard enterprise Windows NT Server market.

CS150 highlights Tandem's Windows NT Server clustering strategy

Roel Pieper, CEO of Tandem, said, "Just a year ago, Tandem announced an intent to leverage our NonStop technologies and become a key market player in the emerging Windows NT space, particularly in clustering. The far-reaching alliance with Microsoft was the foundation. Additional partners, including Computer Associates, were announced along the way. Now, in the last two months, the multiple building blocks of our strategy have come together."

"ServerNet technology, already the de facto cluster interconnect standard, was enhanced in June with a six-node switch for scaling Windows NT Server clusters; our open, clustered middleware for Windows NT Server, especially the NonStop SQL/MX database, was launched in May with an impressive demonstration of its power; and today, we introduce the first product in a planned family of clustered Windows NT Server-based systems. The CS150 is our first truly 'Tandem-ized' Windows NT Server -- it incorporates many of the high-availability characteristics that Tandem has pioneered over the last 22 years."

Pieper concluded, "The cluster is the computer, and Tandem is leveraging its clustering heritage to provide one-stop shopping for all the products that customers need to build reliable, scalable, and cost-effective Windows NT Server clusters."

Tandem recently demonstrated the world's largest Windows NT Server cluster, using key Tandem components. Tandem's open, clustered NonStop SQL/MX ran a two terabyte database with a 30 billion row table (based on a data warehouse from Dayton Hudson); the cluster itself consisted of 64 processors on 16 Tandem Windows NT-based servers linked by Tandem's ServerNet cluster interconnect. Code-named "2Ton" ("two terabytes on Windows NT"), this huge clustered system is generating a valuable body of experience that is accelerating Tandem's ability to bring multi node commercial Windows NT Server clusters to the Windows NT Server marketplace.

"Compaq strongly supports industry standards, and in particular, is committed to making ServerNet technology as an industry standard that is available to all vendors," said John T. Rose, senior vice president and group gffers high bandwidth is required to realize the full benefit of clustering technology."
