Tuxera Reliance™ family preserves critical data in demanding automotive environments, while ensuring peak device performance.

The challenge

Magneti Marelli, leading supplier of high-performance automotive systems, was commissioned by several Formula One teams to develop a “black box” data logger – a recording device for race data on their Formula One cars. The number one customer requirement was of course speed, but it was also vital that the solution not sacrifice reliability in preserving critical race data. Further complicating the issue of performance vs. reliability, Formula One systems must survive brutal, computer-hostile environments, and are under strict regulation for system attributes like size, weight, processor and memory type. The Magneti Marelli system uses a CompactFlash card for memory with the Wind River VxWorks 6.6 operating system. Engineers tried several file systems including HRFS for VxWorks, but were unable to configure the file system to meet the customer’s requirement for throughput speed.

The results

As the Magneti Marelli engineering team discovered, Tuxera Reliance™ offers a custom-tunable architecture known as Dynamic Transaction Point™ technology, which allows the developer a high degree of flexibility in finding the optimal balance between performance and data-at-risk for any use case. Whereas other file systems the team tried were either fast or reliable, Reliance enabled Magneti Marelli to offer their Formula One customer significant performance gains without sacrificing the reliability that they needed. Reliance accomplishes this with an architecture that performs regular transactions where data is moved from a “working state” to a “known good” state. Developers can control how often transactions occur and what triggers them according to time, system events (like file close), or through run-time application control.

By implementing Reliance, Magneti Marelli easily met the Formula One customer’s requirements for speed and reliability. Riccardo De Filippi, Magneti Marelli Motorsport head of electronics product line had this to say; “Using Tuxera Reliance allowed us to meet the performance requirements of our Formula One customer while maintaining the failsafe operation they needed. We won’t hesitate to use Tuxera software again when performance and reliability are top priorities.”
