Datalight Invited to Present Two Sessions at Embedded World 2017


BOTHELL, Wash., – February 17, 2017 – Datalight Inc., the leading developer of file systems and flash memory drivers for the Industrial Internet of Things, announced that Technical Product Manager Thom Denholm has been invited to present two sessions at the Embedded World conference in Nuremberg, Germany, March 14-16, 2017.

The two sessions are “Reliably Committing Data to the Media Through the Linux Kernel” and “Avoiding the Brick – Seamless Updates in Embedded Devices.” Both topics are of particular interest to embedded engineers trying to develop fast, reliable and feature-rich devices for a variety of industries.

The first session (March 15, 5:00 – 5:30 p.m.) discusses the circuitous path from an application write instruction to the media commit in the Linux kernel. With more coders than ever building applications for a Linux or Android environment, a knowledge of how to reliably commit the data to the media is of vital importance.

This session will explain details of the Linux write-behind cache, flush and fsync calls, barrier requests and file system ordered writes. It will also explore how file systems behave in these situations, focusing on two reliability techniques – journaling and transaction points.

Thom Denholm’s second session (March 16, 3:30 – 4:00 p.m.) explores the risk of complete failure during an update of a device, and shares techniques that can be used to mitigate failures. This session explains how a transactional file system can seamlessly handle system updates of any size or scope. A power failure will never result in a brick, and no major changes are required to the design, even in a minimal embedded environment.

Denholm and other Datalight personnel will be available to meet on the exhibit show floor in Hall 4, Booth 544, co-located with Logic Technology.

The Embedded World Conference is the world’s largest exhibition and conference on the design and application of embedded hardware and software. The conference runs from March 14-16, 2014 at the Nuremberg Messe.
