The new version of FreeNAS 10 is now on the way. Currently, it still in Beta version. You can either wait for the final release or simply grab it now and test it on your own platform. I have downloaded and test it on my Proxmox VE 4.2 platform. Overall it works great. FreeNAS 10 comes with many interesting features, redesigned UI and many more.
I have created a video tutorial showing step by step installing FreeNAS 10 on my server. Its pretty easy and straight forward. I hope you enjoy the video.
