System log of the Unix and other worlds


What to use for a home NAS?

Flattr this!

A few weeks ago I started to think about to merge my old home server and my NAS (old ICYBOX IB-NAS4220 – don’t you want one?) into one piece of hardware. I was facing decisions what hardware and what OS should I choose for this new server. Even Linus Torvalds was solving a similar issue recently…

After some googling I have finally chosen CFI A-7879 case. It has four 3.5″ Hot-Plug SATA drive bays and 1 internal 2.5″ for the system (SSD in my case also used as a ZFS write cache device). I fell in love at first sight :-) With an appropriate motherboard and 8GB RAM it has turned into a really cool piece of furniture.

OK, that was a hardware side, what about SW?

ZFS is my bread and butter therefore I tended to choose some configuration allowing ZFS on this station. Debian with FUSE ZFS? Too slow. ZFS on linux? Not stable enough. Some kind of OpenSolaris forks (OpenIndiana, illumos, SchilliX)? I use many GNU tools I would like to keep. FreeBSD (nas4free, FreeNAS)? Dtto. Even it After some tests with FreeBSD I convinced myself it was not what I was looking for. I finally ended up with Debian/kFreeBSD. Wheezy. Yes, got a standard Debian GNU environment, Debian packages repository, FreeBSD kernel with the ZFS support in version 28. After some tweaking with NFS related daemons it works like a charm now! Running NSF, miniDLNA, MythTV, OwnCloud, Postfix, Dovecot IMAP, Apache, MySQL…

And what kind of HW & SW configuration do you use for your home NAS?
