Stratus servers will keep Beijing Olympic traffic flowing

0 comments

The challenges of transporting 3-million Beijing Olympic athletes, media and spectators efficiently to more than 300 sporting events and 1 000 cultural activities will be eased by a technologically sophisticated underground traffic system. 

Traffic control, monitoring and management of that system will be controlled by applications running on ultra-reliable servers from Stratus Technologies, the company has announced.
Stratus servers will host the traffic control, monitoring and management software for the underground transportation system linking Beijing’s Olympic venues.
The underground system is a circular 5,5km roadway connecting surface roads and vast underground parking facilities with the Beijing Olympic Park where major Olympic sporting venues are located, including the National Stadium, National Aquatics Center, Sports Center Gymnasium, and National Indoor Stadium.
A computerised tunnel intelligence management system located in the mission-control monitoring center provides realtime information that enables accurate, reliable and rapid response to ever-changing conditions in the loop, keeping traffic flowing efficiently and travelers safe.
System integrator and application provider, Shanghai Hi-Tech Control Systems (Hite) of Nanjing and Shanghai, partnered with the regional Singapore office of US-based Stratus Technologies to provide a complete traffic control and management solution on a fault-tolerant server platform.
The configuration includes two Stratus ftServer 4400 systems for database and I/O processing; a variety of workstations for operations, engineering, network management and maintenance; Ethernet switches; data acquisition devices; and other components and peripherals.
The constant collection of information from video monitoring and data collection devices throughout the tunnel system to the I/O server makes possible immediate analyses of input, evaluation of conditions, multi-point communications, and proactive traffic management.
Large video screens in the control center also display this data and video information to workers and supervisors on duty in real time. All information is stored to a unified database and used for data mining, activity reporting and operations management.
Each ftServer system contains the equivalent of two tightly coupled industry-standard x86 servers that run simultaneously in lockstep, with each processing the same data at the same time. To the operating system and application, the two physical server halves appear as one single logical server. Should one half suffer an issue that causes it to take itself out of service, the other half continues to run the operating system and application software without interruption, thereby eliminating unplanned application downtime, failover and data loss.
Stratus server uptime availability is field-proven to be better than 99,999%, the server industry’s highest uptime reliability for Windows and Linux applications.
