NAS raid with Debian?

Are there any readily available, inexpensive (US$200-500), NAS
(Network Attached Storage) boxes in the 1-3TB capacity that are
capable of running Debian and NFS?

I'm looking for a device that can export a RAID-1, either ext4 or ZFS,
capacity in the 1-3TB range (two disks, each of that capacity,
mirrored) via NFSv[34] with gigabit networking.

Any suggestions? Any experience to share?


Thanks!

Rick

You are best to build your own, given that the majority of cheap NAS
boxes use Freescale ARM or even MIP's chips. The poor little buses in
these things are barely able to transport between 10-50mbit between
the CPU and attached storage devices. So your performance is always
going to be marginal. Certainly nowhere near the performance of a
cheap x86_64 based board attached to a Sata disk.

You can pick up relatively inexpensive atom or amd e series mobo's or
even laptops with ESATA for the 200-300$ range and then just add esata
caddy to them.

In my experience Most non-x86 NAS platforms are based on the Marvell Kirkwood SoC, which actually does a pretty good job of serving data. I can get 300+ Mbit of NFSv3 out of my iomega ix2-200 running wheezy and a 3.8 kernel.

As above, the iomega ix2-200 meets these requirements, and I only paid about AUD$280 for mine including 2x1TB disks 2 years ago. You can probably get them even cheaper these days. They were much cheaper than equivalent QNap or Synology boxes at the time. I'm experimenting with BTRFS on mine at the moment, which seems to work at least as well as EXT4+RAID 1 for my work loads.

Is it the SoC or the Switch chipset doing the heavy lifting there?
What conditions do you get that throughput? The Kirkwood SoC's are a
bit better than some of the rubbish out there, it is important to note
that there are some good Marvel SoC's (i.e Kirkwood) and some Rubbish
ones (i.e Amarda) I have seen them flail for instance with high
numbers of IO writes (for instance bit-torrent, DRBD backing store,
NFS as VM backing store) on synology X12. - Don't get me going on
QNAP's

Given it is a different arch, less hardware, less expandable etc I
simply can't recommend people use them given you can build an x86_64
low TPW style system for less than 200$ (NZ dollars). You do have the
advantages that you get an all in one unit so there is that.

Thanks! Nigel,

That sound about like what I'm looking for.

Amazon has the Iomega 35550 StorCenter IX2 2 bay 4TB (2x2TB) for US
$333. This seems to be a newer model of the one you have. Some of
the reviews sound pretty good. Though, there were a few reviews
complaining about DOAs.

Are there instructions for putting Debian on it, assuming there's
nothing about the 35550 that might cause problems?

They also have the Iomega 35427 StorCenter ix2-200 2 TB (2 x 1TB) for
US$289. Is this the model you have?

Enjoy!

Rick

You don't want this one (ix2). This is based on the older Orion chipset and I can't say how fast it will be.

Are there instructions for putting Debian on it, assuming there's nothing about the 35550 that might cause problems?

Funny you should ask ;) I blogged about it here: Installing Debian to disk on an ix2-200.

They also have the Iomega 35427 StorCenter ix2-200 2 TB (2 x 1TB) for US$289.  Is this the model you have?

That's it. It's a pity the 6TB/4TB versions of the ix2-200 are so much more expensive.

Nigel

Roll your own with an HP Proliant microserver (the N40L series that are
just being replaced). I bought mine for about £120 a couple of months
ago. Add a pair of 3TB disks also at £100 each. Add more memory (it comes
with 2GB; I replaced that with 8GB) and a second NIC if required. Power
usage is fairly steady at 7W. The resulting cost is towards your upper
end but it's a (very) good piece of kit.

Or a lower-end QNAP, which runs Linux (but not Debian
specifically). Again, you'll need to add a pair of 3TB disks.

Thanks! Chris,

I'll look into that setup as well. My application is space and budget
constrained, so cheaper is better. We don't need all 3TB right now --
though ask me again in a couple of years... (: so maybe I'll go with a
couple of 1TB's to keep the cost down.

Enjoy!

I've recently bought a HP microserver N40L and run DEBIAN on it:

> http://itcrashed.wordpress.com/2011/12/09/hp-proliant-n40l-micro-server/

It is cheaper than a 4 bay NAS and I am pleased with the performance.
I've payed � 209 for the 2GB RAM/250GB HD model. Okay, I am not going to
use the 250Gig HD, but I could not find an empty one. Mine is equipped
with 4 2GB WD RED drives in a RAID5 array, booting from a 8BG USB-Stick

I am running Debian on a Zyxel NSA320 with 2 2TB drives using RAID 1
Cost about $110 less drives
It has been very reliable

I have 2 drives in RAID 1 and encrypted so performance is not great
I use it for a backup server

Hi,

I'm looking at installing Debian on one of these:

http://www.megabuy.com.au/seagate-stbf500300-goflex-satellite-500gb-mobile-wireless-portable-hard-drive-p10274465.html

It has built in wireless capability (and battery) with the 500GB disk.

A serious limitation of the unit is that it creates it's "own" WiFi
network and doesn't participate in an existing WiFi network.... that's
what I really want to fix.

The firmware download includes a uImage file as follows:

# file uImage
uImage: u-boot legacy uImage, Linux-2.6.32, Linux/ARM, OS Kernel Image
(Not compressed), 2313388 bytes, Tue Dec 20 21:36:47 2011, Load Address:
0x80008000, Entry Point: 0x80008000, Header CRC: 0x01B18018, Data CRC:
0x0AA8AC17

So, I'm hoping that it will be possible to make this unit much more
useful as a very portable Debian box.

Cheers
AndrewM
