Thanks for that, I'd forgotten about the sheevaplug. That is probably
closest to what I'm looking for, because I can connect a SATA hard
drive to the GuruPlug, and put my own kernel modules and software
daemons on there I think. That means the iSCSI enterprise target (iet)
would probably work on there and would do what I want for providing a
network block device (NBD). As for gigabit ethernet, I think probably
100 Mbps ethernet is fast enough for most usage given that the rotating
hard drive is probably the slowest part of the system anyway. Gigabit
is nice but you need to use jumbo frames.<br>
<br>
Thanks for the Addonics NAS links, it looks like a pretty workable
product too. If I could put my own firmware on that, it might be
perfect, but I don't see any links about loading my own firmware on
there. I do need the iSCSI target. I used to have a Linksys NSLU2
(slug) which I had my own firmware on, and I used it to make a huge
RAID1 mirror of 2 drives, but the 200MHz Xscale CPU was so slow that it
would take 24 hours to resync the array if it got shut down uncleanly,
which it did regularly because of some software issue I think. (It was
even on a UPS.)

<font size="+1"><tt>Hi CLUEbies,<br>
<br>
I am working on a project which requires modular storage in an
industrial environment. I am thinking about trying to use "external"
hard drives for the data storage. That is, the hard drives will be
separate modules. I'd like to use ethernet with iSCSI as the
interconnect, so I can have many:many disk/server relationships, and
also do software RAID over the targets.<br>
<br>
I've used the Linux iSCSI enterprise target (iet) software and it's
great. I'm thinking that a disk with a little single board computer or
other microcontroller, with ethernet and SATA interfaces, could run the
iSCSI enterprise target and export the disk as a network block device
on the ethernet. Ethernet gets us a bunch of other spiffy advantages
that we couldn't do with eSATA, firewire, USB, etc.<br>
<br>
<b>Do any of you know if anyone is making such a thing?</b> It
doesn't have to be in an industrial enclosure, we can make that (it
would just have power and ethernet connectors on the outside of the
enclosure). Inside the enclosure would be the disk and the little
computer, connected to each other via SATA.<br>
<br>
We can make the system software for the little computer, including the
web cgi etc. for management and SMART, I just need somewhere from which
to source the hardware. I looked around a bit and the only external
drive enclosures I see are eSATA and the like.<br>
<br>
Thanks,<br>
Jim<br>
