F-Series

TrueNAS F-Series

All-NVMe high-performance storage. 2U dual-controller, up to 30 GB/s, Fibre Channel and 100 GbE.

TrueNAS F60 / F100 chassis – 2U all-NVMe dual-controller storage

F-Series: All-NVMe High-Performance Storage

The TrueNAS F-Series condenses enterprise storage into 2 rack units: 24 Gen4 NVMe bays, dual-controller HA and up to 30 GB/s throughput from a single chassis. Where HDD-based systems hit their latency ceiling, the F-Series delivers consistently low response times — even under very high concurrency.

Available as the F60 for classic all-flash workloads and as the performance flagship F100 with 48 cores per controller, double the network capacity and up to 20 PB raw all-flash capacity. Both models use the full TrueNAS Enterprise suite — inline compression, fast deduplication, NVMe-oF, Fibre Channel and automated HA failover.

Architecture and expansion

The 2U chassis combines 24 Gen4 NVMe bays with two AMD EPYC controllers and scales through NVMe and SAS shelves.

24 NVMe Gen4 drive bays

Front-loading 2.5" hot-swap slots, all wired as Gen4 NVMe. Drives from 3.8 TB to 122 TB yield up to 20 PB raw in a 2U chassis.

Dual-controller HA

Two AMD EPYC controllers (32 or 48 cores) with active/standby failover, virtual IP migration and zero data loss on switchover.

Distributed Write Log

Write log distributed across multiple NVMe drives instead of a classic SLOG — lower sync-write latency and no dedicated cache devices required.

NVMe + hybrid expansion

Scale with ES24N NVMe shelves (up to 6× on F100) or SAS shelves for hybrid pools — 4× 6.4 TB NVMe read cache in front of the HDD tier.

Available storage media

All media ship with full TrueNAS Enterprise integration — including hardware AES-NI encryption, S.M.A.R.T. monitoring and hot-swap support.

NVMe Gen4 SSDs (front bays)

• 3.8 TB to 122 TB per SSD
• 2.5" U.2/U.3 hot-swap
• Optional SED and FIPS 140
• Up to 20 PB raw in a 2U chassis

Hybrid tier: SAS3 HDDs (expansion shelves)

• 7200 RPM Enterprise Nearline

• 4× 6.4 TB NVMe read cache in front
• Optional SED and FIPS 140

Power, climate, dimensions

Redundant hot-swap power supplies, out-of-band management via IPMI and UPS signal integration are standard. The 2U format enables high rack density at under 1.2 kW peak load.

Is the F-Series right for your project?

The F-Series is the right choice if at least one of these applies:

→ You need pure all-NVMe performance, no HDD tier
→ Consistently low latency under high concurrency required
→ High rack density needed — 2U instead of 4U
→ AI/ML, database or 4K/8K media workflows
→ Connecting to an existing FC SAN

If you need >100 GbE or tri-mode (HDD+NVMe in one chassis), the V-Series fits better. Pure HDD capacity is served more economically by the M or R-Series.

Frequently asked questions

What is the TrueNAS F-Series?

The TrueNAS F-Series is iXsystems' all-NVMe high-performance platform. Packed into a 2U chassis with 24 Gen4 NVMe bays, it delivers consistently low latency and up to 30 GB/s throughput — built for AI/ML pipelines, databases, virtualisation at scale and 4K/8K media production.

Which models are part of the F-Series?

The F-Series consists of two models: F60 (32 cores per controller, 10 PB raw / 20 PB effective all-flash capacity, up to 4× 100 GbE) and F100 (48 cores per controller, 20 PB raw / 40 PB effective all-flash capacity, up to 8× 100 GbE). Both run the full TrueNAS Enterprise suite.

What is the difference between F60 and F100?

The F100 is the performance flagship: 48 cores per controller instead of 32, 30 GB/s instead of 20 GB/s throughput, twice the network ports (8× 100 GbE optional), six instead of four 32 Gb FC ports, and scaling to 6 NVMe expansion shelves instead of two. The F60 already covers most enterprise workloads; the F100 targets hyperscale, AI training and consolidated multi-tenancy.

Does the F-Series support high availability?

Yes, both models are available as an optional dual-controller HA configuration. If one controller fails, the second takes over transparently — including virtual IP migration and without data loss. Recommended for production databases, virtualisation and any mission-critical scenario.

Which expansion shelves are compatible?

F60 scales to up to 2× ES24N (NVMe) or 4× ES60/ES102 (SAS hybrid) — up to 10 PB hybrid capacity. F100 scales to up to 6× ES24N or 8× SAS shelves — up to 20 PB hybrid capacity. Hybrid configurations use 4× 6.4 TB NVMe as a read cache in front of SAS pools.

What networking and FC options are available?

F60: up to 4× 10/25/40/100 GbE optical, plus 4× 32 Gb Fibre Channel. F100: up to 4× 10/25/40/100 GbE or 8× 100 GbE optical, plus 6× 32 Gb Fibre Channel. Out-of-band management via IPMI and the TrueNAS WebUI are standard on both models.

Which protocols and hypervisors are supported?

File: SMB v1/2/3, NFSv3/v4 with RDMA, FTP, WebShare. Block: iSCSI, iSER (RDMA), NVMe-oF (TCP/RDMA), Fibre Channel, OpenStack Cinder. Object: S3-compliant, MinIO Alstor. Hypervisors: VMware (VAAI, vCenter, VM Warn/Stun), Proxmox plugin, Hyper-V (VSS, ODX, CSV), KVM, XenServer, OpenShift, Kubernetes CSI.

When is the F-Series the right choice — and when V, M or R-Series?

The F-Series fits when you need all-NVMe in 2U: AI/ML, low-latency databases, dense virtualisation, FC SAN connectivity. If you need >100 GbE or tri-mode (HDD+NVMe in one chassis), the V-Series is the better choice. Pure HDD capacity workloads are served more economically by the M or R-Series — we will tell you straight.
