H-Series

TrueNAS H-Series

Compact and mission-critical: 2U, optional HA, hybrid or all-flash — NVMe in every bay.

Compact and Mission-Critical

The H-Series is TrueNAS's compact platform for edge sites, small data centres and branch offices. In just 2U it combines 12 tri-mode bays, optional dual-controller HA and full NVMe support — selectable per bay. The H-Series therefore covers hybrid pools, pure SAS pools and pure all-NVMe pools in the same chassis.

The series comprises three models: H10, H20 and the new H30 (launched in January 2025) — positioned by iXsystems as the "Swiss Army Knife of Storage". All models run the full TrueNAS Enterprise suite — snapshots, replication, inline compression, fast deduplication, RDMA and Truecloud backup.

Architecture and expansion

The 2U chassis combines tri-mode bays with optional HA and 100 GbE options — in a compact form factor.

12 tri-mode bays

Each of the 12 hot-swap bays accepts SAS HDD (8-26 TB), SAS SSD (1.9-15.36 TB) or NVMe SSD (3.8-61.4 TB) — selectable per bay.

Dual-controller HA optional

All three models are optionally available with dual-controller HA — failover without data loss and with virtual IP migration.

100 GbE-ready (H20/H30)

H20 and H30 support 2× 40/100 GbE or 4× 10/25 GbE — enough bandwidth for virtualisation and VDI.

Up to 1.5 PB all-NVMe in 2U (H30)

With 12× 61.4 TB NVMe drives, the H30 reaches up to 1.5 PB effective flash capacity — ideal for AI inference at the edge.

Is the H-Series right for you?

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

→ Storage requirement under 3 PB raw
→ Edge site or branch with limited rack space
→ Optional HA wanted — without a 4U footprint
→ Compact 2U form factor mandatory
→ Mixed workloads, but with NVMe option per bay

Above 3 PB, 100 GbE+ or 99.999% uptime requirements, the V or M-Series is often a better fit — we will tell you straight.

Frequently asked questions

What is the TrueNAS H-Series?

The TrueNAS H-Series is iXsystems' compact 2U platform with optional dual-controller HA, hybrid or all-NVMe configurations and 12 tri-mode bays. It targets edge sites, small virtualisation environments, backup targets and compact AI inference nodes.

Which models are part of the H-Series?

Three models: H10 (entry), H20 (mid-range) and the new H30 — launched in January 2025 as the "Swiss Army Knife of Storage". H30 doubles CPU cores and cache versus H20 and delivers up to 1.5 PB all-NVMe in just 2U.

What does tri-mode mean on the H-Series?

All 12 front bays support either SAS HDDs (8-26 TB), SAS SSDs (1.9-15.36 TB) or NVMe SSDs (3.8-61.4 TB) — selectable per bay. So you can build hybrid pools, pure SAS pools or pure all-NVMe pools in the same chassis.

When is the H30 the right choice instead of the V160?

H30 is the right pick for < 3 PB capacity, edge or branch deployments, optional HA and a compact 2U footprint. The V-Series only pays off above 1 PB consolidated storage, > 100 GbE or Fibre Channel networking and mission-critical workloads with 99.999% uptime.

Which networking options are available?

Onboard 4× 1 GbE base-T (all models), plus an additional 2× 10 GbE base-T on H30. Optionally up to 4× 10/25 GbE or, on H20/H30, 2× 10/25 + 2× 40/100 GbE. Fibre Channel with 2× 16 Gb (H10/H20) or 2× 32 Gb (H30).

What is the power consumption?

H10: approx. 200 W average, 250 W peak. H20: approx. 300 W / 350 W. H30: approx. 400 W / 450 W. Power supplies are redundant and 80 Plus Platinum certified.

Which expansion shelves are supported?

H10 supports 1× ES24 or ES60. H20 and H30 each support 1× ES24, ES60 or ES102 — letting you scale hybrid pools to up to 3 PB raw without leaving the H-Series compact footprint.

Which protocols and hypervisors are supported?

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