I'm running centos 7 and i wondered if there's any software for it that will make an attached USB drive behave as an NDAS device on my network. I understand that an NDAS device has a device ID. thanks for any help.

Just did a quick search and I did find an archive of the old drivers. The driver was only beta status so who knows how well it really worked.

I put "linux ndas" into a search engine and one of the top results is https://github.com/iocellnetworks/ndas4linux

The readme contains:
Both Ximeta and Iocell websites appear to be gone, and there are no commits since 2013, so the big question would seem to be: Why do you want a NDAS instead of something more common/standardised/supported?

when I did a search all I found was NDAS client software whereas I want the server end so my machine behaves like the NDAS storage point

That's because it was a proprietary system - they only released the connection packages, (unless "bits an pieces of the NetDisk Power 400T OS and manuals." contain anything useful).

If it doesn't, you're probably out of luck - that's one of the major problems with proprietary software - it can disappear or break and then its users are screwed.

You could always try raising an issue on GitHub and seeing if they respond, though the lack of any activity or other online presence makes that seem unlikely.

Which brings us back to why bother? What is the benefit of using an unsupported technology? What does NDAS/LPX give you that cannot be solved using other methods?

If you want to be a network storage server, NBD or iSCSI are standard and offer block storage over the net. If you specifically want something below TCP/IP like LPX, then you could also revive FCoE. At least it has published standards.

Not sure how Ximeta patented anything to do with network disks as Panasas was doing that over 20 years ago.
