How to install FreeNAS to create your own NAS

FreeNAS is a free and open source OS born to create customizable NAS (network-attached storage) supporting the powerful ZFS filesystem. Based on FreeBSD, it allows to create a resilient storage for your business data.

ZFS supports snapshots and encryption, both useful features in business enviroments. Furthermore, RaidZ (a software RAID solution) offers data protection without many issues and limitations of traditional RAID setups.

FreeNAS supports all the most adopted file sharing protocols like Apple’s AFP, NFS, CIFS / SMB and iSCSI.

In this tutorial we’ll show you how to install FreeNAS to build your own – totally customizable – NAS.

Note: for simplicity’s sake we created a virtual machine with 4 virtual disks to simulate a common NAS setup.

Download FreeNAS from the official site and burn it on a CD/DVD (or use a virtual drive like we did).

Boot the machine with the CD/DVD:
