Fault-Tolerant High Capacity File System for Mentor Graphics Nucleus
Reliance Nitro gives developers precise control over file system behavior to optimize performance for diverse use cases while ensuring data is free from corruption even in the event of a power failure or unexpected shutdown.
Datalight Inc., leading developer of file systems known for fast performance and solid reliability, today released a version of its flagship Reliance Nitro file system pre-ported to Mentor Graphics Nucleus RTOS v3.x.
Reliance Nitro is the choice of leading OEMs who build devices where data reliability is critical. As the Internet of Things gives rise to more devices that capture and store data from their environment in real-time, developers are demanding systems that have the real-time features of Nucleus RTOS but also robust data storage capabilities. Reliance Nitro gives developers precise control over file system behavior to optimize performance for diverse use cases while ensuring data is free from corruption even in the event of a power failure or unexpected shutdown.
“Customers appreciate the quality and reliability of Datalight software and the responsiveness of their technical team,” said Scot Morrison, General Manager of Embedded Runtime Solutions for Mentor Graphics “‘the integration of Reliance Nitro allows embedded developers to use Nucleus RTOS in demanding environments which require the reliable management of significant quantities of data in their embedded devices..”
“We are excited to offer a pre-ported version of Reliance Nitro for Nucleus, helping our mutual customers complete their projects faster,” said Ken Whitaker, VP of Engineering for Datalight. “The collaboration with the Mentor Graphics Nucleus team has enabled us to make a great operating system even better.”
Reliance Nitro integrates with the Virtual File System (VFS) in Nucleus Ready Start, enabling developers to use Reliance Nitro as a completely reliable replacement for the default Nucleus FAT-compatible file system or run Reliance Nitro alongside it to provide enhanced reliability just for critical system and user data.
Devices today are storing more data and have need for large volume sizes. Reliance Nitro surpasses the Nucleus FAT file system by supporting volume sizes up to 32 TB (terabytes) which allows use of SDHC (high-capacity) and SDXC (extended capacity). Developers also have the flexibility to use sparse files or expand a file without deleting and recreating it. These features make writes faster and use disk space more efficiently.
Reliance Nitro offers POSIX-compatibility and supports standard C-libraries, giving developers a high level of configuration flexibility. Its unique tree-based metadata and extent-based architecture also provides fast file performance. A system of configurable transaction settings the company calls Dynamic Transaction Point™ technology allows developers to balance performance with the amount of user data at risk for a wide variety of different use cases. It is also capable of working with virtually any storage medium, and is highly efficient whether an OEM is designing with hardware-managed or software-managed storage media.
Reliance Nitro file system diagnostics offer full metadata and optional file data CRCs (Cyclic Redundancy Checks), which enable developers to continuously monitor data reliability in any embedded system, and provides early warning of imminent media failure to avoid data corruption.
In addition to the new Nucleus version, Datalight products are also available for Linux, Android and other embedded operating systems allowing complex systems that use multiple operating systems to share a common data store.
Reliance Nitro ships in ANSI C source code and includes a robust set of developer tools and complete documentation. Technical support from Datalight’s highly-respected support team is available via phone and email. Runtime distribution can be licensed per unit or per project.
