XigmaNAS is network-attached storage (NAS) server software with a dedicated management web interface (written in PHP). It is free software under the terms of the Simplified BSD license.
XigmaNAS is a continuation of the original FreeNAS code, which was developed between 2005 and late 2011. It was released under the name NAS4Free on 22 March 2012. The name was changed to XigmaNAS in July 2018. On SourceForge, it was elected “'Community Choice' Project of the Month” twice, in August 2015 and March 2017.
XigmaNAS is an embedded open-source NAS software distribution based on the latest release of FreeBSD. It developed from original FreeNAS 7 code and updated to work with the current latest FreeBSD releases. However, "XigmaNAS preserves FreeNAS’s original m0n0wall/PHP architecture and introduces experimental support for the ARM architecture."
XigmaNAS supports sharing across Windows, Apple, and UNIX-like systems. It includes ZFS v5000, Software RAID (0,1,5), disk encryption, S.M.A.R.T. and email reports etc., with the following protocols: SMB, Samba Active Directory Domain Controller AD, FTP, NFS, TFTP, AFP, rsync, Unison (file synchronizer), iSCSI (initiator and target), HAST, CARP, Bridge, UPnP, and BitTorrent. All of this is configurable by its web interface.
XigmaNAS is installable on almost any boot medium including LiveCD optionally with a small USB flash drive for config storage if necessary, both for x86-64 and x86-32 computer platforms up to version 10.3. As of version 11.0, XigmaNAS no longer supports x86-32, but version 10.3 is still getting updates. XigmaNAS can be installed on Compact Flash, USB flash drive, SSD, hard drive or other bootable devices, and supports advanced formatted drives using 4 kB sectors. The software distribution is currently distributed as in ISO image (.iso, ~370 MB) or USB flash drive image (.img, ~320 MB) format, and in source form.
A special small footprint embedded image is also available (.img, ~150 MB). The preferred method is the embedded installation onto a USB stick, Compact Flash card (CF), or hard disk HDD/SSD, for which XigmaNAS was designed. The XigmaNAS OS will load into system memory, eliminating system writes to a drive except for configuration changes written to an archive. Flash devices are more energy efficient, and the updating process can be done by WebGUI in the browser, downloading and installing a new firmware image.
The original FreeNAS project derives from m0n0wall.
The FreeNAS 0.7 branch was end-of-life'd in late 2011 after the FreeNAS name was legally acquired by iXsystems, Inc. Starting with version 8.x, new iXsystems developers rewrote FreeNAS and legacy FreeNAS 0.7 was no longer available for download.
The legacy FreeNAS 0.7 code was unable to be developed any longer under the same name, and a name change was necessary. The founder of FreeNAS (Olivier Cochard-Labbé) donated the original FreeNAS source code to the NAS4Free project. With the support of the former developers, namely Daisuke Aoyama and Michael Zoon, it carries on the original FreeNAS code base. FreeNAS 8.x.y and up is a software fork of the original FreeNAS with a new rewritten code-base, continuing the old branded name. In 2018, the project applied for the XigmaNAS trademark in order to protect the brand prior to the release of v11.2.
The awards listed below are legacy FreeNAS ones.
Further readings prior to 2012 are referring to the legacy FreeNAS .07 precursor branch.
