back to article Build a 14.5 watt data center in a shoebox

Those supercomputing guys love to build their massive data centers full of hardware and high-end cooling systems. They make you feel like a real man or at least a real geek, which is important. Folks with smaller egos and perhaps smaller hands might consider building a tinier, more energy-friendly supercomputer. Consider this …

What I miss

What I miss on those boxes is storage and extendibility.

For years I'm searching for a low-power system which has lots of PCI-slots and can work with at least 4 harddrives. There are a lot of uses for such a machine. For example as a meshed WLAN router, or as an IPTV server. Both applications don't really need a lot of processing power, but a lot of PCI-slots. The second even needs a lot of harddrive storage.

boooring!!

Sounds like my Linksys NSLU2's...Load debian linux, add and external hard drive, scrap off a resistor to get the cpu running at 200MHz and you have a nice little package that only draws 11 watts. I use one to run a weather station (using 1-wire devices and oww), one as a media server and one for fun. The NSLU2 costs about $80. If you take up the low power data center challenge, you should consider using a few NSLU2's in the mix.

Japanese characteristics?

""The OpenMicroServer has what we like to think of as very ‘Japanese characteristics,'" said Tomoyasu Suzuki, president of Plat'Home. "It doesn't stand out, and it doesn't complain..."

Just a few changes and they'll sell like hot cakes...

Provide SATA support, so the units can be upgraded in the future.

PoE sounds great for avoiding being knee-deep in powerbricks. Maybe offer different power supply options?

Remove any artificial constraints on disk size -or customers who will buy these units will not be impressed.

Drop the price to 150 USD, and people will buy spare ones for backup.

I would strongly suggest giving customers a good product at a fair price which suits their needs. Give the customers the freedom to tweak these units and some amazing things will happen. If the manufacturers are crafty, they will get all the ideas they need for developing the next generation of this kind of product from the people who have tweaked their units.

When this is done, brand loyalty will be all the greater.

"The LinkStation Mini uses a pair of 5,400RPM 2.5 inch notebook drives to perform its magic, making it the only Buffalo storage unit not to run on SATA drives."

Not so. The LinkStation Mini DOES use SATA drives (see http://www.buffalotech.com/files/products/LinkStation-mini_DS.pdf) This is not surprising, as 2.5" SATA drives have become the norm in the laptop world.

NSLU2

I've got an NSLU2 with a pair of hard drives mounted in an old DVD Recorder case. Two cables - mains and network - and it all just... works. Tops. I flashed the firmware to run uNSLUng, but I feel Debian might be in order - I quite fancy the extra flexibility.

RE Just a few changes and they'll sell like hot cakes...

This is also sold by a typical Japanese vendor

Here are some Japanese manufacturer/vendor ethics to consider:

- Any change demanded by a customer is considered wagamama.

selfish is the closest translation but it is more like an insult that you as the customer ask the manufacturer to change something in his product because the manufacturer knows everything better so the customer should just do his job which is handing over money and shutting up.

- Artificial constraints ? Well why would the manufacturer remove that ? That way you will not buy the next model. We are still talking about Japan yes ? The country where replacing my hard disk in my toshiba would have set me back around 50 000 Yen. Finding the exact hard disk on ebay and installing it my self amounted to 8000 Yen.

-Drop the price. Wrong wrong wrong If you are not paying a lot you don't get quality. Japanese products are for some reason more expensive in Japan (with 5% sales tax than say Belgium with 21% sales tax). In general the Japanese consumers will pay whatever without even thinking if the price/product-you-get ratio is acceptable.

Thanks, I already know the "pleasure" of Buffalo gear

Having had a poor experience with their gear in the past, we nevertheless in desperation last year bought a buffalo NAS just to tide ourselves over for a couple of weeks until the real gear arrived. Wow, what a mistake. Even the nontechnical staff joined us in throwing it off the roof.

Which I might mercifully have forgotten had their name not come up this week...when someone complained to me that none of their buffalo gear was reliable.

Perhaps it's produced by a buffalo's....central processing system.

14.5 W is huge.

Want something lower Wattage? Any Linx box with a network connection can be presesed into service as a "data center" and if you don't need too much storage, you could run a small ARM Linux board with flash memory etc and get something going for less than 3W.

The smallest web server I've seen is http://d116.com/ace/ and only uses a few mW that it can steal form the RS232 wires. You could fit a few thousand of those in a shoebox. Of course this stretches the definition of "data center" somewhat.

They are awsome toys and tools.

"The LinkStation Mini uses a pair of 5,400RPM 2.5 inch notebook drives to perform its magic, making it the only Buffalo storage unit not to run on SATA drives"

Not true, many of the kuroboxes support PATA/IDE, and also the previous line of Linkstations (HGLAN) which ran on PPC. I have no preference between SATA and PATA as neither of them are bottlenecks.

Unfortunately the newer ARM9 models running at 400mhz are much slower at applications than the older 266mhz PPC models. Never the less, I have mine running Apache, SSH, Asterisk (the Callweaver branch), OpenVPN, and Samba for file share. When I only had one Linkstation, I connected USB hard disks to it for back up, now I have an RSync script between multiple Linkstations.

I have looked at many products for low end server platforms for running trivial daemons on a LAN. I bought the Linkstations explicitly to install Debian. In my opinion the Linkstations are the best value I've seen for this purpose.

For instance the Linksys NSLU units mentioned above only have 16meg RAM, while most Linkstations have 128meg. It might not affect their intended purpose, but when you configure a GraphicsMagick thumbnail cron job, that ram helps.

I have heard bad things about Buffalo's customer service, and unlocking them isn't "supported", so it's not for those who don't know what they're doing. That said, the unlocked Linkstations are so cool. Check out linkstationwiki.net for ideas/code.

Mac mini isn't even close

When the article started I couldn't help but thinking a Mac mini cannot be too far away from these specs, however, I was wrong.

A similarly sized Mac mini uses a max of 110watts (probably during burning a DVD) and works at up to 95 degrees F.

Of course it offers a dvi out port, which these don't offer, as well as a higher power CPU. But still limited in expandability.

Ok, so this is a nice piece of kit. I'd be curious how quickly a few of these setup in a grid could encode video for me. The last video project I did took over 14 hours to encode on a Core 2 Duo CPU.

Have a look at the Excito Bubba

I have a couple of these http://www.excito.com/products.html

One of them does this:-

Linux 2.6, Debian; Apache web server; Dovecot IMAP server (IMAP, IMAPS); Postfix SMTP server; Fetchmail (for fetching email from other pop or imap accounts); File server (http, samba, ftp); Download manager (bittorrent, http, ftp); Printer server; DAAP streaming media server (Firefly); UPnP streaming media server (Mediatomb)

The other one is used as a backup and for 'development' (Well, OK, playing with it.). You can also install most ARM Debian packages that you might want like MC, SQLite, MySQL (if you really have to) etc.

They each use < 10 watts. Both of them have current up-times of about 100 days.

A new one with more stuff is due out later in the year.

overpriced, underpowered, no applications or IO

This is the box that fatgadget are selling for USD. 500. But once you've bought one, what then? It won't run windows, solaris, hp-ux or any other other commercial operating system (I said commercial, for the linux boys & girls). if you do want to run Linux applications, you'll have to port them to it's PPC architecture and squeeze them into the 128MB of memory. Once there, then what?

These things can't interact with the outside world - except through the spare ethernet port - no digital I-O, no serial/parallel ports - not even a USB.

If you want to do real work in an embedded environment, buy a TINI or a dedicated embedded system.

If you are thinking of gettig one of these, save your money. Buy a housebrick and paint it white. it'll have the same functionality, be cheaper and use less power. ................ summary: pointless

Which one is?

"But once you've bought one, what then? It won't run windows, solaris, hp-ux or any other other commercial operating system (I said commercial, for the linux boys & girls)."

Plenty of commercial Linux systems available since, oh, 1995 or so.

"if you do want to run Linux applications, you'll have to port them to it's PPC architecture"

By compiling them. Not very hard.

"and squeeze them into the 128MB of memory."

That's plenty for a data server.

"Once there, then what?

Well, since they're intended for ethernet networks, that appears reasonable.

"- no digital I-O, no serial/parallel ports - not even a USB."

Ie, no pointless ports the target market doesn't want.

"If you want to do real work in an embedded environment, buy a TINI or a dedicated embedded system."

Fine. Did you especially want to talk about embedded systems? Perhaps posting to an article about embedded systems would be a good idea; this is about data servers.

"If you are thinking of gettig one of these, save your money. Buy a housebrick and paint it white. it'll have the same functionality, be cheaper and use less power. ................ summary: pointless"

@Pete - correction

apparently this brick^H^H^H^H^Hcomputer does have a couple of USB ports, and a whopping 8 BITs of digital I-O. I apologise for my earlier ommission and would like to correct my summary of the device. Paint a housebrick white and tie a USB cable around it. You can then use either one as an anchor for a model boat - there: it does have a use, afterall.

To even hint at the possibility of using it in a datacentre (except possibly as a doorstop) is laughable. Although the article does admit that the box "limps along ...". I already have boxes that perform all the functions this thing claims (ref: mini-itx). I've been using them for years. They're cheaper, more flexible and support a greater range of O/S, being "proper" PC architectures 'n'all.

Probably the best use for this product is what Buffalo suggest (top of page 2): aim it at windows - preferably someone else's.

To you, maybe just a Box of Tricks, to others, Pure Magic.

"A savvy and admittedly deranged admin, however, could take this tiny hardware and build a very energy-efficient data center in a desk drawer."

Crikey, Ashlee, that's a bit harsh/rich, especially coming from El Reg. Now an AEStranged admin, however, who are very, very crafty and have a liberal use of the word 'supersubatomic', would lead with many factoring advices, for tasks geared as Mother and Nature intended, rather than as cowards deploy ..... for Ye Ole Seemly Seamless Godisagoddess Paradigm Shift into Parallel Dimensions for Overall SuperComputing Control[s].

Buy NSLU2

Add storage through a caddy or even USB flash sticks.

Install debian.

Draws a max of about 7.5 watts (IIRC), though obviously if you have drive caddies or USB bus-powered device you have to factor those in). I have two. One runs my home mail/web/SSH gateway server. The other runs a web fronted torrent app and hosts my media collection, shared via SAMBA and ushare UPnP server so the Xbox 360 can stream stuff.

Fantastic little machines, shame linksys decided to sell them only as a NAS and not a low powered home server.

I guess the difference is that you can get a NSLU2 for about £50 (as usual just convert U.S dollar sign to £ and you get the UK price) whereas the cheapest QNAP boxes seem to start @ about £110??

I wanted to build a standalone system which does XYZ over ethernet but single board computers, embedded systems etc all start at about £100 with a possibility of not being able to use linux wheras you can pickup the NSLU2 cheap and know its gonna work. Rebox it, install your app, job done!

Infineon ADM5120

Well after spending forever looking around and commenting on this post, I decided to give the "Infineon ADM5120" a go from omnima.co.uk. I found them on the openwrt forum and decided I might as well give it a go. It was only £19 although I decided to buy the usb key with the OS already installed for £7 (if im happy with it then I can just buy my own keys from ebuyer for like £4 and do it myself).

Its only 175mhz with 16mb but it beats trying to fight protection a manufacturer has put on a router and its near enough the same as ebay prices. I only want to run some basic python web scraping scripts and sell it as a device so it should be fine and it works out to be about £25 for a full system you can sell on ..

£19 - board

£2.50 - power cable

£4 - usb 1gb (could prob go lower/cheaper than this!)

The NSLU2 isn't a router, and it's not a fight, just grab the debian installer image and use the NSLU2's "firmware upgrade" option on the administration page. It's 266MHz & 32MB, which still isn't much I guess.

It's been out a few years, anyone know of a similarly low-priced and hackable NAS that's a bit beefier?

This sounds familiar...

Looks like the NSLU2, but actually marketed as what the NSLU2's being used: low-power servers. I've yet to be able to use my NSLU2 at its full potential, as somehow I'm unable to get gcc to work natively, and the 'toolchain' binaries are gone from the original download sites. Oh dear ...

I'd think about these as they are MIPS (another non-Intel option!) of SGI fame, and they have TWO ethernet ports, which make them a good option for a low-cost firewall/router. Believe me, I'm in dire need of one right now, if only to stop the script kiddies on their tracks!

Of course, I could just buy the mini-ITX and build it myself, but *that* option goes around the $1000 mark, way too high for my discretionary budget. Ow.
