PoE NAS

One-wire network-attached storage

Start with a small enclosure with a spinning disk. Add some minimal hardware to run embedded linux with a single gigabit ethernet port. Connect to PoE switch (or through a midspan) to power the device (4-5 watts should be sufficient). Clients on the LAN could transfer files via SSH/FTP/NFS/SMB, or any other practical protocol.

       4-5 watts to reliably run a 7200rpm disc? Mmmmkay...   

       Volume is going to be limited. Transfer speeds will suffer, too.

       Could be done with a Hitachi Microdrive, but the max would then be about 8gb…   

       Some 2.5" units might just about meet the criteria.   

       Better to drive it with a CMOS CPU running embedded C as native rather than bothering with the Linux overhead.

       The power supply on a 1 terabyte WD MyBook is rated for 2.1 watts. I've seen PoE hardware running embedded linux on ARM consume only 3 watts, so 5 watts seemed feasible.

       so the idea is a standalone network/network-powered hard-disk ? ... presumably using a hardware protocol which allows hot plugging.

       This gives me an idea for a sort of software algorithm, that would let you rapidly analyze billions of web pages for a specified term. This "search engine", if you will, would allow you to look and see if something like this already exists. For example, you could put in a query like "nas poe" and see whether somebody has already invented such a thing.   

       I'm tellin' ya, this is gonna be big. So big, that it deserves a really BIG name. In fact, I think I'll call it "tentotheonehundredth".

       Okay, I apologize for the (excessive) snark. It just seems like there've been quite a few product ideas posted lately where the author didn't do so much as a cursory web search to see if such a thing already exists. I think (and the FAQ concurs) that this should be part of the due diligence when posting an idea. If you discover that a similar idea already exists and you still want to post your idea, then that's fine— but it behooves you to add a link or reference to the existing invention, as well as to specify what distinguishes your idea.

       Yes, you should be careful- it might turn out to be a Boojum …   

       Keep a Railway Share handy!

       I'll just use my trusty Boojum reflector, thanks. My way or the Conway.

       I spent 20 minutes searching the web for such a product, confused why I could not find it through my usual channels. I found nothing. ytk, if you have seen this already, perhaps you could post a link to it.
ed, May 06 2012
  

       Sure. Like I said, put "nas poe" (no quotes) into the Googles. First result. Also for pretty much any combination of the words "power over ethernet nas". Not sure what search terms you were using...
ytk, May 06 2012
  

       Thank you for the link; my search engine did not find that. That is pretty much what I was looking for, though I do not need "harsh environment" support.
ed, May 06 2012
  

       What do you mean you don't need it? You're here, right?
