High Level Comparison

FreeNAS and NexentaStor Community are Storage Operating Systems that support many of the same features like CIFS, SMB, NFS, and iSCSI protocols. Each system works with OpenZFS (v5000) with feature flags, most virtualization platforms, and have support, training and certification available.

FreeNAS

Started in October 2005 by Olivier Cochard-Labbe, FreeNAS is a free and open-source software network-attached storage (NAS) system based on FreeBSD and the OpenZFS file system and is licensed under the terms of the BSD License. In September 2009, the development team realized that FreeNAS would need to be completely re-written in order to incorporate modern features like a plug-in architecture, updates to the base system, and an up-to-date User Interface. To carry this out, the FreeNAS Team transferred the project over 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.

NexentaStor Community Edition

Alex Aizman and Dmitry Ysupov created the Nexenta OS project after Sun Microsystems released the bulk of its Solaris operating system under free software licenses as OpenSolaris. NexentaStor is derived from the former Nexenta OS and based on the illumos operating system, utilizing OpenZFS as an underlying filesystem. The software delivers unified file and block storage services to consumers. NexentaStor Community edition is free up to 18TB of raw storage and does not include all the features of the professional version.
