TernFS: New Linux File System Unveiled by a Retail Giant

In a context where big data management has become a strategic issue for retail companies, the open source release of the new Linux file system TernFS by one of the largest algorithmic trading firms marks a turning point. This technological advance illustrates the rise of open source solutions in enterprise IT infrastructures, meeting the needs for interoperability and robustness. TernFS, developed by XTX Markets, does more than offer a simple distributed file system: it offers a major digital innovation, capable of managing colossal volumes of data with flawless reliability and large-scale adaptability, particularly for sharing critical data between multiple geographic locations. The democratization of this collaborative technology under GPLv2+ and Apache 2.0 licenses thus paves the way for a new era of high-performance middleware in Enterprise Linux environments. TernFS’s Technical Specifications and Architecture for Massive Data Management in Linux

At the heart of TernFS’s innovation lies its ability to efficiently manage large, immutable files in a distributed environment. Unlike traditional systems like NFS, whose scalability quickly reaches its limits, TernFS was designed to meet the requirements of an IT infrastructure reaching up to 10 exabytes of logical storage, with a capacity to manage approximately one trillion files and 100 billion directories.

This system uses a distributed architecture based exclusively on standard hardware and a traditional Ethernet network, making TernFS an accessible solution for businesses without the need for expensive proprietary equipment. Its design is based on:

Data distribution among multiple nodes

, which optimizes load distribution and improves overall resilience.The absence of a single point of failure
for metadata, ensuring service continuity in complex environments. Data redundancy
to protect information against frequent hardware failures in large enterprise data centers. Native support for a multi-region architecture
, essential for companies with internationally distributed data centers.Furthermore, the system management prioritizes immutable files, i.e., files that, once created, are never modified. This technical choice simplifies consistency and replication mechanisms, while being perfectly suited to data used in trading algorithms and machine learning models, where historical data must be kept intact.

The middleware thus implemented allows TernFS to ensure efficient interoperability between various enterprise applications, facilitating data exchange and sharing in a native Linux environment. This innovative architecture adapts perfectly to the constraints of large companies and opens up numerous opportunities for this use, particularly in sectors with high volume and reliability requirements, such as mass retail.

The impact on the optimization and security of corporate IT infrastructures

By leveraging TernFS, IT departments can now manage hundreds of petabytes of data related to inventory management, sales forecasts, and customer behavior analysis. This system plays a key role in the development of IT infrastructures, ensuring fast transfers and secure storage.

Notable benefits include:

Increased fault tolerance

thanks to data distribution and replication across multiple nodes.Concurrent access for a large number of users
up to one million clients, facilitating collaboration and parallel work within the enterprise.Simplified access and permission management
via integrated authentication mechanisms and compatibility with Enterprise Linux standards for security. Finally, the adoption of TernFS in Linux file systems illustrates a strong trend toward open source and modular tools in modern IT infrastructures. This fosters digital innovation by enabling deep customization and easy integration with other software components used in business, thus promoting effective collaborative technology.

The Challenges of Open Source for File Systems: TernFS under Free Licenses

Opening the TernFS source code under the GPLv2+ and Apache 2.0 licenses is a crucial element that meets the expectations of a large part of the Linux community and Enterprise Linux professionals. This dual license enables:

Wider adoption

in different contexts, by providing strong legal guarantees. Active community participation
for the continuous improvement of the system, essential for strengthening security and functionality. Increased compatibility
with a variety of open source and middleware projects, facilitating its integration into heterogeneous IT environments. This strategy also promotes transparency, a significant aspect for companies keen to control their infrastructure and avoid risks associated with proprietary and opaque elements. Furthermore, the fact that TernFS has been used for over a year as part of intensive machine learning efforts at XTX Markets attests to its robustness and maturity, with no reported data loss.

The role of open source in this context goes beyond simple code distribution: it is a lever for innovation propelling large retailers towards increasingly efficient and interoperable data management standards, which facilitate interdepartmental collaboration.

This philosophy is part of a more global approach where knowledge sharing and collective contribution are key factors for the sustainability of IT infrastructure solutions, particularly in the era of big data and the Internet of Things.

Concrete use case of TernFS in a large retail company

For a large retail company operating in the mass retail sector, the ability to efficiently manage file systems has become a daily challenge. Deploying TernFS in its infrastructure offers concrete benefits:

Optimized data sharing

between different departments, whether logistics, marketing, or inventory management.

Improved performance in processing large files related to purchasing analyses and forecasts.
Reduced risks associated with outages. through redundancy and distribution across multiple geographic locations.
Facilitating audits and compliance thanks to improved data traceability and immutability after creation.
Another key factor is the ease of integration with existing systems: TernFS, being Linux-native, integrates easily with other middleware components and can interact with hybrid architectures combining proprietary and open source solutions. This interoperability provides the flexibility essential for evolving in a constantly changing digital ecosystem. As a result, the company can quickly respond to the varying needs of its various departments in terms of file management and collaborative sharing.

The power of TernFS to manage a million clients simultaneously perfectly illustrates its potential in a complex Enterprise Linux environment, where the demand for storage and processing resources is very high.
