TrueNAS Core vs TrueNAS Scale
TrueNAS is a popular open-source storage platform that offers robust features and high performance. It provides two main editions: TrueNAS Core and TrueNAS Scale.
Introduction
TrueNAS is a popular open-source storage platform that offers robust features and high performance. It provides two main editions: TrueNAS Core and TrueNAS Scale. In this article, we will compare these editions in terms of architecture, scalability, management and features. We will also include tables for easy comparison.
Architecture
TrueNAS Core is based on the FreeBSD operating system, known for its stability and security. It follows a traditional monolithic architecture, where all components are tightly integrated into a single system. This architecture is well-suited for single-node deployments and offers excellent performance and reliability. TrueNAS Core utilises the powerful ZFS file system for data management, providing features such as data integrity, snapshots, replication and encryption.
On the other hand, TrueNAS Scale is based on Linux and embraces a microservices-based architecture. It allows for both single-node and multi-node deployments, making it highly scalable. In a multi-node setup, TrueNAS Scale utilises a distributed storage model, where data is distributed across multiple nodes. It leverages the OpenZFS file system for data management, offering features like erasure coding for increased fault tolerance and distributed storage capabilities.
| TrueNAS Core | TrueNAS Scale |
|---|---|
| Based on FreeBSD | Based on Linux |
| Traditional monolithic architecture | Microservices-based architecture |
| Single-node deployments | Supports both single-node and multi-node deployments |
| Utilises ZFS for data management | Utilises OpenZFS for data management |
Scalability
TrueNAS Core is primarily designed for single-node deployments, limiting its scalability options. However, it can still be expanded by upgrading hardware components such as adding more drives or increasing storage capacity. TrueNAS Core supports up to 12 drives per system and provides RAID-Z for data redundancy.
In contrast, TrueNAS Scale excels in scalability. It supports both single-node and multi-node deployments, allowing you to scale horizontally by adding more nodes to the cluster. This distributed storage model enables you to scale to hundreds of drives across multiple nodes, providing a highly scalable solution. TrueNAS Scale offers distributed storage with erasure coding, which enhances fault tolerance by allowing data to be reconstructed even if multiple drives or nodes fail.
| TrueNAS Core | TrueNAS Scale |
|---|---|
| Limited to single-node deployments | Supports both single-node and multi-node deployments |
| Can be expanded through hardware upgrades | Can be expanded horizontally by adding more nodes |
| Supports up to 12 drives per system | Can scale to hundreds of drives across multiple nodes |
| Provides RAID-Z for data redundancy | Offers distributed storage with erasure coding for increased fault tolerance |
Management
Both TrueNAS Core and TrueNAS Scale offer a web-based management interface, providing an intuitive and user-friendly way to configure and manage the storage systems. The management interfaces are designed to simplify the setup and configuration processes.
TrueNAS Core provides a comprehensive set of storage management features through its web interface. It allows you to manage file sharing protocols such as SMB, NFS and AFP, as well as block-level protocols like iSCSI and Fibre Channel. Additionally, TrueNAS Core supports plugins and extensions, enabling you to extend its functionality for specific use cases.
TrueNAS Scale, with its microservices-based architecture, offers advanced management features for distributed storage. It allows for centralised management of multiple nodes through the web interface, making it easier to manage and monitor a cluster of storage nodes. Like TrueNAS Core, TrueNAS Scale also supports plugins and extensions, providing flexibility and customisation options.
| TrueNAS Core | TrueNAS Scale |
|---|---|
| Web-based management interface | Web-based management interface |
| Provides a comprehensive set of storage management features | Offers advanced management features for distributed storage |
| Supports plugins and extensions for additional functionality | Supports plugins and extensions for additional functionality |
| Simplified setup and configuration | Centralised management of multiple nodes |

Conclusion
TrueNAS Core and TrueNAS Scale are both powerful storage solutions with their own unique strengths. TrueNAS Core is well-suited for single-node deployments and offers a comprehensive set of storage management features. On the other hand, TrueNAS Scale is designed for scalability, supporting both single-node and multi-node deployments with advanced management capabilities for distributed storage.
Whether you choose TrueNAS Core or TrueNAS Scale depends on your specific requirements, such as the need for scalability, fault tolerance and centralized management. Evaluate your needs carefully and consider the features provided by each edition to make an informed decision.
Remember, both editions are actively maintained and offer excellent performance and reliability, making them reliable choices for your storage needs.
