According to The How-To Geek, TrueNAS has released its major 25.10 update with significant performance improvements and new enterprise capabilities. The update introduces NVMe over Fabric (NVMe-oF) support that enables remote storage to perform like local NVMe drives, dramatically reducing latency and protocol overhead compared to traditional iSCSI. Performance testing shows over 75 GB/s of read bandwidth from a single appliance, with the system supporting up to 20PB of NVMe flash for F-series systems and 40PB for M-series deep archive configurations. The update also includes OpenZFS 2.3.4 improvements for better storage allocation and a new Versioned TrueNAS API built on JSON-RPC 2.0 over WebSocket for faster web interface performance. This represents a substantial leap forward for storage performance that deserves deeper technical analysis.

The NVMe-oF Revolution in Storage Architecture
The introduction of NVMe over Fabric support in TrueNAS 25.10 represents a fundamental shift in storage architecture that goes beyond simple performance improvements. Traditional storage protocols like iSCSI were designed for spinning disks and introduce significant protocol overhead that becomes a bottleneck with modern NVMe storage. NVMe-oF essentially extends the PCIe bus over the network, allowing remote storage to behave exactly like local storage at the protocol level. This architectural change is particularly crucial for distributed computing environments where storage and compute are increasingly disaggregated. The ability to achieve microsecond-level latency through RDMA implementations means that applications no longer need to be storage-local to achieve maximum performance.
Transforming AI and High-Performance Computing Workloads
For organizations running AI training, scientific computing, or financial modeling workloads, the performance characteristics of TrueNAS 25.10 could fundamentally change their infrastructure design. GPU-accelerated workloads have historically been limited by storage I/O, with expensive local NVMe arrays being the only solution for feeding data-hungry AI models. With NVMe over Fabric, organizations can now centralize their high-performance storage while maintaining the low-latency access required by GPU clusters. This enables more flexible scaling of compute and storage resources independently, potentially reducing total cost of ownership while improving resource utilization. The support for 400Gbps Ethernet interfaces ensures that network bandwidth won’t become the new bottleneck in these high-performance scenarios.
Enterprise Adoption Challenges and Considerations
While the performance numbers are impressive, enterprise adoption of these new capabilities requires careful planning. The RDMA implementation requires specialized networking hardware and configuration expertise that may not be present in all organizations. Additionally, the massive scalability – supporting up to 40PB in M-series configurations – introduces new management challenges around data protection, backup strategies, and disaster recovery. Organizations considering deployment should evaluate their staff’s readiness to manage these advanced features and consider the total cost of ownership beyond the storage system itself. The networking infrastructure upgrades required to support 400Gbps interfaces and RDMA-capable switches represent significant additional investment.
Shifting Competitive Landscape in Open Source Storage
TrueNAS 25.10 positions the platform firmly in competition with proprietary enterprise storage solutions from vendors like Dell EMC, NetApp, and Pure Storage. The performance characteristics now rival systems costing significantly more, while maintaining the flexibility and cost advantages of open source. However, this also increases the competitive pressure on other open source storage solutions like Ceph and Linux-based ZFS implementations. The comprehensive feature set demonstrated in this release shows iXsystems’ commitment to maintaining TrueNAS as a leading enterprise storage platform rather than just a hobbyist solution. This could accelerate enterprise adoption of open source storage solutions across multiple industries.
Strategic Implementation Recommendations
For organizations considering TrueNAS 25.10 deployment, a phased approach is recommended. Begin with the NVMe/TCP implementation for broader compatibility before investing in RDMA infrastructure. The new Update Profiles feature provides a sensible framework for managing risk – starting with Mission Critical for production systems and potentially moving to Early Adopter for test environments. Organizations should also consider the skills development required, as the advanced features in this release demand deeper understanding of both storage and networking technologies. Proper implementation could yield significant performance benefits, but requires careful planning and execution to realize the full potential of these groundbreaking capabilities.
