Building on the foundation of TrueNAS 25.04 “Fangtooth,” iXsystems has released TrueNAS 25.10 “Goldeye”, a major update designed to enhance performance, simplify system management, and strengthen enterprise capabilities. The new release incorporates modern storage technologies, refined data handling through OpenZFS 2.3.4, and expanded virtualization support for high-performance environments.
TrueNAS 25.10 introduces NVMe over Fabric (NVMe-oF), offering both NVMe/TCP for the Community Edition and NVMe/RDMA for the Enterprise version. The feature delivers direct, high-speed remote data access with latency levels approaching locally attached NVMe storage.
Real-world testing showed over 75 GB/s read bandwidth from a single appliance, making the platform particularly effective for AI training, virtualization, and database workloads. The system also supports new 400 GbE network interfaces for extreme throughput.
The integration of OpenZFS 2.3.4 provides key fixes and enhancements for more predictable performance and improved write consistency. The updated allocator algorithm optimizes data placement within ZFS storage pools, ensuring faster and more uniform operations under heavy workloads. Additional refinements to compression, block cloning, and ARC reporting further increase efficiency and visibility into real-time cache utilization.
Enterprise deployments gain a substantial capacity boost, with the TrueNAS F-Series now supporting up to 20 PB of NVMe flash and the M-Series extending to 40 PB of deep archive storage. Hardware support has been expanded to include next-generation Terabit Ethernet adapters for higher network performance.

A significant architectural change in this release is the introduction of the Versioned TrueNAS API, built on JSON-RPC 2.0 over WebSocket. The new API delivers faster, more responsive system interaction and ensures long-term compatibility for integrations.
Official documentation is available at api.truenas.com, with active development underway for plugins that integrate with Kubernetes, VMware vSphere, and Proxmox VE.
TrueNAS 25.10 also modernizes its update system through Update Profiles, allowing administrators to choose between Early Adopter, General, Mission Critical, and Developer channels. Each profile aligns system updates with an organization’s stability and feature-adoption goals, simplifying maintenance and minimizing risk.
The Web UI receives multiple usability improvements, including a redesigned iSCSI configuration wizard, enhanced YAML editor for app configuration, more responsive performance dashboards, and a new Users Page with predefined administrative roles for faster setup.
For centralized control, the release enables TrueNAS Connect, a web-based monitoring platform offering health tracking, alert delivery, and inventory management. The service is available for community testing until December 1, 2025, with an Enterprise rollout scheduled for March 2026 via connect.truenas.com.
Virtualization takes a major leap with the new Data Hypervisor, which separates the Enterprise-ready Virtualization interface from experimental container management.
Running on the KVM hypervisor, it now supports high-availability virtual machines and adds disk import/export compatibility with VMDK, VDI, QCOW2, RAW, and VHDX formats. These features streamline VM migration between TrueNAS and external environments such as VMware and QEMU.
The 25.10.0 release delivers several performance and stability refinements, including ZFS improvements for encrypted snapshot replication, Direct I/O support, and memory management enhancements that prevent out-of-memory crashes.
Network handling is smoother with better DHCP-to-static transitions, and the UI has been redesigned across key pages including Updates, Users, and Datasets.
Breaking changes include a shift to open-source NVIDIA GPU drivers (supporting Turing and newer GPUs only), removal of the AUTORID backend from Active Directory mapping, deprecation of internal certificate authority functions, and migration of SMART monitoring to cron-based tasks. SMB shares also now use a preset-based configuration system, with older configurations automatically converted to the “Legacy Share” preset.
TrueNAS 25.10 finalizes the improvements introduced in its release candidates with numerous bug fixes, including Samba security updates, dataset replication stability, VM disk export validation, NVMe-oF connection reliability, and app schema validation handling. The update also resolves issues with AMD GPU detection, API backward compatibility, and unwanted cron email notifications.
