FreeNAS vs Openfiler

FreeNAS and Openfiler are Open Source network-attached storage operating systems. Both support the SMB and NFS sharing protocolsand provide a web interface for easy management.


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.


Openfiler is based on rPath Linux and is designed to enable storage administrators to make the best use of system performance and storage capacity resources when allocating and managing storage in a multi-platform, business-critical storage environment.
