TrueNAS provides unrivaled data integrity protection by using the OpenZFS enterprise file system. OpenZFS is a next-generation file system in every regard from its self-healing bit rot mitigation to its flexible snapshotting and replication.
OpenZFS is a future-proof 128-bit “scale up” file system that is designed for decades of continuous use. TrueNAS grows from hundreds of GBs to 26PB per system of effective capacity and is designed to make the increase in capacity painless.
TrueNAS offers you the flexibility of choice, providing SMB, AFP, and NFS for file storage, iSCSI and Fibre Channel for block storage, and S3-compatible APIs for object storage. Every common operating system, hypervisor, and application is supported.
TrueNAS delivers a perfect balance of price and performance that puts many all-flash arrays to shame. It uses TrueCache™ to leverage RAM, NVME and SSD flash storage alongside spinning disks for flash-like performance with spinning disk capacities and economics. And for environments needing the utmost in performance TrueNAS also offers all flash options.
Originally developed at Sun Microsystems, but now Open Source, OpenZFS is an enterprise-grade file system that iXsystems has delivered to more users than anyone. We pride ourselves on working closely with the OpenZFS community to help make OpenZFS the greatest file system ever written.
