Reliance Assure
Rest assured – you control your
data-at-risk
Embedded systems in safety critical domains – automotive, industrial, medical, defense, and avionics – contain increasingly complex software components from multiple vendors and sources. This complexity creates challenges related to software compliance, which is costly and time-consuming. Tuxera Reliance Assure™ helps you achieve your compliance and reliability goals for developing high-quality, safe systems. With Reliance Assure, we aim to help you reduce the time for certification of your embedded systems.
Reliance Assure embedded file system is specifically designed for applications where certifiability is a mandate and fail safety is paramount. Our transactional file system is precision-engineered to protect mission- and safety-critical data from corruption. Deterministic file system behavior gives you full control of your data-at-risk. Plus it works with a majority of safety-critical RTOSes.
Why choose Tuxera Reliance Assure
Deterministic data control
All the key file system operations of Reliance Assure are deterministic, providing unprecedented predictability. It's also a copy-on-write transactional file system, meaning live data is never overwritten – and makes the system extremely power fail-safe. True transactional architecture ensures complete metadata and file data integrity. Plus, Dynamic Transaction Point™ technology gives you full compile-time and run-time control over critical data.
Guaranteed compliance and traceability
Every line of code has been crafted to exact coding standards, such as MISRA C:2012, and was developed following the Automotive SPICE framework. This brings you full bi-directional traceability, code reviews, and verification. What's more – the available Design Assurance Package add-on gives you a solid document set to build your certification artefacts.
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 "uncontrolled shutdown" situations, there's no need to waste time or resources replaying a journal or performing file system cleanup. Whether shutdown is orderly or chaotic, Reliance Assure rapidly mounts to a known-good state, ensuring consistent and predictable boot times.
Award-winning support
Customer success is a cornerstone of our values. 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 to expectations and on schedule.
