Why CRCs Are Important

Datalight's Reliance Nitro and journaling file systems,such as ext4, are designed to recover from unexpected power interruption. These kinds of "post mortem" recoveries typically consist of determining which files are in which states, and restoring them to the proper working state. Methods like these are fine for recovering from a power failure, but what about a media failure?

fsck and chkdsk

Before embedded devices, file systems were designed to work in servers and desktops. Power loss was an infrequent occurrence, so little consideration was given to protecting the data.

Reliability with ext4

The challenge - making ext4 just as reliable as Datalight's Reliance Nitro file system, within limitations of the POSIX specification. Unlike most real world embedded designs, performance and media lifetime are not a consideration for this exercise.

Multithreading in Focus: Performance & Power Efficiency

We're constantly on the lookout for ways to help our customers boost performance and improve power efficiency, and often our inspiration comes by way of the conversations we have with them. Recently, several of these discussions highlighted user scenarios where the complexity of the application would benefit from an enhancement to the classic Dynamic Transaction Point™ technology found in our Reliance Nitro file system.

Help! Why are my devices failing?

In conversations with the embedded OEMs we work with, a common issue affects almost every manufacturer - the cost of diagnosing and fixing causes of field failure. This impacts time-to-market and pulls resources from development for field diagnostics and post-mortem analysis. This issue is especially relevant due to the following reasons:
