The company’s new exFAT file system plug-in is a hardware feature for Android and Linux-based embedded systems that improves data resiliency in devices like DVRs, drones, cameras and data recorders.
Nuremberg, Germany, April 9, 2024 /PRNewswire/ — Unexpected power loss can cause serious data loss in data recording devices. In response to this challenge, Tuxera announces an innovative and low-cost hardware data resilience and failsafe feature for embedded system designers. Tuxera Persistence Manager™ is the premium feature of Tuxera’s Microsoft exFAT add-on for enterprise deployment of the exFAT file system. The feature is intended for embedded system designers working with Linux-based data recorders, especially in automotive, industrial applications, consumer electronics, and commercial drones.
Tuxera launches Persistence ManagerTM: optimizes hardware costs and prevents data loss on recording devices.
Applications of this technology cover use cases where continuous video recording is required and data must be preserved and accessible. In these cases, the data recorded via video is crucial for decision-making and can serve as evidence, for example, in the event of a traffic accident. Devices such as digital video recorders (DVRs) and car surveillance cameras, industrial cameras used in security or vision systems, and commercial drones that collect environmental data are possible target devices for this innovation.
The Tuxera Persistence Manager allows the embedded systems designer to use software to control how much data is written to the cache before its contents are committed to the storage medium and at what time interval.
Data flushing is the process of committing all data from memory buffers to storage media. It prevents data loss in the event of a sudden power outage and is therefore crucial in ensuring system security against power failure. “Normally, recording devices store data in non-volatile memory,” he says Teem Sivonen, product manager at Tuxera. “If the device suddenly loses power, such as unplugging or hardware failure, the data in the recording process has not had time to flush to disk and is lost forever.”
In a power loss situation, super- or ultra-capacitors are typically used to provide a small amount of power while data flushing takes place. But supercapacitors can be very expensive depending on the capacity, voltage and other special requirements. Based on the actual user scenario, in a car DVR system, the price may vary up to 4 USD or more per supercapacitor. In addition, hardware components are subject to supply chain changes and vulnerabilities, and therefore may delay product release to market in accordance with required product plans.
With this feature, the dependency on supercapacitors can be optimized to ensure safety in the event of a power failure and prevent data loss. The software gives system designers the flexibility to specify the size of chunks of data to flush and when, ensuring that data is safely stored in the event of a power crash or loss.
An additional benefit for exFAT users of Tuxera is achieving a longer lifetime of flash storage media compared to implementing more complex alternatives – such as implementing application-level flushing or tweaking the system configuration. Continuously writing, erasing, and rewriting data to storage fragments and consumes flash, reducing the number of P/E cycles it can withstand. Tuxera’s exFAT solution features patented allocation techniques that mitigate the problem of early flash burnout – working in tandem with Tuxera’s Persistence Manager.
“If a vehicle crashes while recording video with a dashboard camera, the resulting loss of power can cause the last 30 seconds or more of footage to be lost,” adds Sivonen. “Tuxera Persistence Manager ensures that if the recording device unexpectedly loses power, as much data as possible is saved and stored. The user can adjust software settings to control how often the device flushes data to disk, reducing both the size of the supercapacitor required and the amount of data in dangers.”
Tuxera Persistence Manager will be presented at Tuxera’s booth at Embedded World 2024, in Hall 4, Booth 4-438. The company welcomes interested customers, partners, media and analysts to speak with their experts at the booth or send an inquiry to [email protected].
