FreeNAS® vs Ubuntu Server with ZFS on Linux

FreeNAS and Ubuntu Linux are Open Source operating systems that support many of the same features like ZFS, SMB, copy-on-write, and snapshots. Both operating systems offer a robust feature set capable of handling NAS and SAN applications.

FreeNAS

This Open Source project was started in October 2005 by Olivier Cochard-Labbé and quickly grew as a popular network-attached storage operating system. By September 2009, the development team realized that FreeNAS would need to be completely rewritten in order to incorporate modern features like a plugin architecture, updates to the base system, and a modern User Interface. To carry this out, the original FreeNAS Team transferred the project to iXsystems, who moved from a m0n0wall and PHP-based architecture to one based on FreeBSD’s NanoBSD embedded build system, the Python programming language, the Django CMS, and the Dojo JavaScript toolkit.

Ubuntu Server

Ubuntu Server is an operating system based on Debian Linux that offers a full range of server features. Development is funded by Canonical, which offers professional support services. Ubuntu Server differs from the desktop edition as it runs in a screen mode character-based environment, though an X Window desktop environment can be added manually. The Server edition is certified to work with VMware ESXi Server, VirtualBox, XenServer hypervisors, Microsoft Hyper-V, QEMU, Kernel-based Virtual Machine, or any other IBM PC compatible emulator or virtualizer. Ubuntu Server utilizes a linux module for kernel security by default.
