Invensys and Stratus Technologies to Offer High-Availability Option for Systems Using ArchestrA Technology

October 242003
LAKE FOREST, Calif., Oct. 23, 2003 -- Invensys and Stratus Technologies today announced that the Invensys line of ArchestrA supervisory and plant intelligence software platforms with Wonderware software is now supported on Stratus(R) ftServer(R) fault-tolerant systems. This marketing and sales collaboration comes as part of an independent application software provider (IASP) agreement that Invensys has signed with Stratus.

"Because our customers rely on Wonderware software for a broad range of industrial application solutions -- from supervisory control to plant intelligence -- they need high-productivity software with optimum system availability at a number of price points," said Steve Lewarne, vice president of product marketing for the Wonderware and ArchestrA business units. "With the addition of the Stratus continuous computing option to Wonderware's latest products built on ArchestrA technology, customers have even more options for supporting some of the most demanding applications in the market today."

The Stratus ftServer family is a full line of Intel(R) processor-based servers designed expressly for critical processes and operations where business continuity, continuous information access and application availability are essential. Stratus servers offer better than 99.999 percent uptime performance on both the hardware platform and operating system, which includes either Microsoft Windows Server 2003 or Windows 2000. To keep operations online, ftServer systems address the primary causes of system downtime and data loss including single points of failure, hardware failover and recovery time, faulty device drivers, human error, component and software revision incompatibilities. The inherent reliability of the hardware's fault-tolerant design, coupled with unique software-availability features and integrated ActiveService(TM) fault detection and isolation technology, aggressively position Stratus against competitors' solutions where reliability and operational simplicity are important.

"As systems integration takes hold within departments, between departments, and throughout the plant, there is a complementary effect," said Jindrich Liska, Stratus director for manufacturing systems. "The availability of applications and the reliability of the IT support infrastructure increase exponentially in importance. Both Invensys and Stratus are very cognizant of their responsibility to help customers achieve productivity and financial goals, and meet regulatory obligations within their operations with reliable, robust, easy-to-deploy solutions."

Invensys' Wonderware software including the Industrial Application Server, which is built on the ArchestrA architecture, InTouch human-machine interface (HMI) software, and the IndustrialSQL Server plant historian, have been tested and validated on the Stratus ftServer 3300 series. The supervisory control systems of these critical production processes require continuous availability.

To date, customers with Stratus ftServer 3300 systems have run their applications with no unplanned downtime caused by the server or operating system since this model was launched in March 2003. This entry-level server is the company's most successful new product to date in terms of quality and user demand.

Only Stratus discloses actual recorded "availability" levels for its products based on reported sey
rvice incidents from the installed base. The ftServer Uptime Meter(SM) is updated daily and can be viewed on the Stratus Web site at The data is based on operating experience of both the hardware and Microsoft(R) Windows(R) 2000 operating system over the past six months.
