TrueNAS

TrueNAS is a universal data platform that enables users to adopt a modern, open-source approach to store and protect their growing data. TrueNAS harnesses the ZFS file system to provide unified storage (File, Block Object, and Apps) with the reliability and performance demanded by virtualization, backup, and many other data-heavy workloads. The TrueNAS CORE edition (formerly FreeNAS) is based on FreeBSD for unified scale-up storage. The TrueNAS SCALE edition is based on Debian Linux for either scale-up or scale-out solutions and offers Linux Containers, VMs (KVM), and scale-out ZFS storage capabilities. Both versions are free to use and work well on a variety of hardware.
