What XigmaNAS is
XigmaNAS is a free, open-source operating system for creating a network-attached storage server. Its WebGUI lets administrators configure and manage the server without relying on the FreeBSD command line. Storage options include ZFS, software RAID, JBOD, UFS and disk encryption, while supported sharing protocols include SMB/CIFS, FTP/SFTP, SSH, NFS, AFP, RSYNC, Unison and iSCSI. The project lists compatible access from Windows, macOS, Linux, iOS and Android systems. S.M.A.R.T. monitoring and email notifications can alert users to drive issues. XigmaNAS also includes a web-based VirtualBox host for virtual machines managed by phpVirtualBox, plus MySQL via MariaDB and phpMyAdmin. It supports 64-bit systems only. Installation options include LiveCD and LiveUSB images, as well as embedded and full upgrade images; minimum OS disks are 2 GB for embedded installs and 4 GB for full installs, with 512 MB RAM for either. Disk encryption is marked unsupported, and the project warns it cannot help recover data encrypted with that feature.
