iXsystems has slotted a second model into its enterprise V-Series storage line, and the TrueNAS V140 runs the exact same software image as everything above it. That matters more than the spec gap suggests: the appliance ships the full TrueNAS Enterprise stack built on Debian Linux and OpenZFS, with dual-controller high availability and automated failover standard on every configuration.
The V140 pairs two 16-core AMD EPYC controllers with 192 GB of RAM, up to 12 TB of read cache, and a rated 15 GB/s of system bandwidth across up to 16 PB of raw capacity. It draws roughly 600W on average, which keeps it viable in racks where power and cooling are hard limits. The chassis is a 4U design with a tri-mode drive layout: 24 front bays accept SAS HDDs and Gen4 NVMe SSDs in any mix, and four rear Gen5 NVMe bays handle dedicated high-velocity caching. Supported protocols include SMB, NFS, iSCSI, Fibre Channel, NVMe-oF, and S3, all bundled rather than licensed per feature.
Because the V140 and the higher-performance V160 share one chassis, you can upgrade in place by swapping controllers one at a time, with no new enclosure and no data migration. The V160 climbs to 30 GB/s with HDD and 40 PB of raw capacity in Hybrid Flash, or 60 GB/s and 20 PB All-Flash, territory aimed at AI training, 8K post-production, and high-density virtualization. The V140 targets file services, backup, archive, secondary storage, and DR targets that mirror a primary platform exactly.
Underneath sits the same open-source foundation as the free TrueNAS Community Edition. The current 25.04 "Fangtooth" release runs Linux kernel 6.12 and OpenZFS 2.2.99, and adds RDMA extensions for iSCSI and NFS, iSCSI block cloning, and Fibre Channel support for enterprise SANs. iXsystems has outlined a 2026 roadmap built around TrueNAS 26 and OpenZFS 2.4, so the platform a V140 ships with today is on a published upgrade path. Licensing is per-appliance with no per-TB capacity metering, no replication or immutability surcharge, and no renewal step-up. iXsystems has not published V140 pricing.
