Power fail-safe file system for resource-constrained systems
Tuxera Reliance Edge™ is the only embedded file system designed to capture and preserve decision-quality data with deterministic behaviour required by today’s autonomous systems. A transactional file system, Reliance Edge protects critical system and user data from corruption, especially for systems where power loss may occur. When paired with a flash memory manager like Tuxera FlashFX Tera, Reliance Edge delivers the functionality of a complete flash file system.
Reliance Edge for INTEGRITY, Free RTOS, and other RTOS es
Protect critical data
Reliance Edge is a copy-on-write transactional file system, meaning live data is never overwritten. This makes the system extremely power fail-safe. True transactional architecture ensures complete metadata and file data integrity. Dynamic Transaction Point™ technology gives developers complete compile-time and run-time control.
Our software provides substantially faster overall performance compared to alternatives. Tuxera’s general-purpose file system I/O testing showed Reliance Edge to have a significantly higher performance in all read tests, as well as nearly all write tests. Our FSIO Test measures a variety of file I/O types, working with virtually any file system, and is included with Reliance Edge.
Ultimate control with determinism
Our configuration options allow developers complete control over which features are included, providing ultimate customizability – allowing our file system to fit your specific use case just the way you need it. Regardless of how it’s configured, its key file system operations are deterministic, providing unprecedented predictability.
Small footprint fits anywhere
Our file system is small and portable, ideal for resource-constrained embedded systems like microcontrollers. It can be configured to use as little as 4 KB of RAM and 11 KB of code.
Fast mount time
After power loss or a system crash, the system must recover rapidly to keep the data stream flowing. In these so-called “dirty” situations, no need to rely on replaying a journal or performing any other file system checks. Reliance Edge ensures your decision-quality data is safe, while mount times are lightning fast.
Tuxera’s team of file system experts will support you all the way from evaluation to implementation, going above and beyond to ensure your project performs flawlessly and on schedule. Our annual support subscriptions for Reliance Edge are available with a choice of service level options, so you can select the right degree of support that suits your needs.
Never overwrites live data. Once data is written, it’s always in a determinate state.
Rapid recovery times
Mounts quickly and consistently after unexpected shutdown/power loss.
Ported to many RTOSs including FreeRTOS, SafeRTOS, μC/OS, ARM mbed, MQX, INTEGRITY, and eMCOS.
