Meanwhile, iXsystems rewrote FreeNAS with a new architecture based on FreeBSD 8.1, releasing FreeNAS 8 Beta in November 2010. Developers Daisuke Aoyama and Michael Zoon continued developing FreeNAS 7 as the NAS4Free project. Cochard-Labbé responded to community objections to "The Debian version of FreeNAS" and resumed activity in the project and oversaw its transfer to FreeNAS user iXsystems. Volker Theile decided that the project best be reimplemented using Debian Linux and shifted his development efforts to the interim CoreNAS project and eventually OpenMediaVault where he continues as the project lead. 7, was due for a complete rewrite in order to accommodate modern features such as a plug-in architecture. In September 2009, the development team concluded that the project, then at release. Volker Theile joined the project in July 2006 and became the project lead in April 2008. The FreeNAS project was started in October 2005 by Olivier Cochard-Labbé who based it on the m0n0wall embedded firewall and FreeBSD 6.0. This separation also allows for TrueNAS system upgrades to be performed through the web interface. The TrueNAS operating system is fully independent of its storage disks, allowing its configuration database and encryption keys to be backed up and restored to a fresh installation of the OS. This image is configured using a USB Flash/CD-ROM bootable installer. As an embedded system appliance, TrueNAS boots from a USB Flash device or SATA DOM. The web interface supports storage pool configuration, user management, sharing configuration and system maintenance. TrueNAS is managed through a comprehensive web interface that is supplemented by a minimal shell console that handles essential administrative functions. TrueNAS supports the OpenZFS filesystem which provides data integrity checking to prevent data corruption, enable point in time snapshotting, replication and several levels of redundancy including striping, mirroring, striped mirrors (RAID 1+0), and three levels of RaidZ. TrueNAS branded hardware – enterprise storage arrays, a network-attached storage (NAS) systems, storage area network (SAN) devices, and High Availability systems, with up to 22 petabytes raw capacity.TrueNAS SCALE – a Linux based hyper-converged version of the TrueNAS platform.TrueNAS Enterprise – an enterprise file server for commercial use, also based on FreeBSD.TrueNAS CORE (previously FreeNAS) – a free file server and expandable platform based on FreeBSD.TrueNAS is the brand for ixSystems' open source network attached storage platform. Advanced TrueNAS features include full-disk encryption and a plug-in architecture for third-party software. TrueNAS supports Windows, macOS and Unix clients and various virtualization hosts such as XenServer and VMware using the SMB, AFP, NFS, iSCSI, SSH, rsync and FTP/TFTP protocols. It also offers hardware, from small home systems to large petabyte arrays, based on the above versions. The TrueNAS range includes free public versions ( TrueNAS CORE, previously known as FreeNAS), commercial versions ( TrueNAS Enterprise), and Linux versions ( TrueNAS SCALE, under development as of January 2021). It is licensed under the terms of the BSD License and runs on commodity x86-64 hardware. TrueNAS is the branding for a range of free and open-source network-attached storage (NAS) operating systems produced by iXsystems, and based on FreeBSD and Linux, using the OpenZFS file system.
