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.

Somebody else needs to take this one... |
|
| |
start with po.. am interested... |
|
| |
he is a duck! am more than interested... |
|
| |
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. |
|
| |
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... |
|
| |
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. |
|
| |
What do you mean you don't need it? You're here, right? |
