1.   Lots of googling - focusing on key technical words like "nbd",
otherwise u will get lots of related stuff....which is also good for
general reading.

2.   Start with high level (and proceed down to network level):

http://www.ibm.com/developerworks/linux/library/l-linux-kernel/

http://www.ibm.com/developerworks/linux/library/l-linux-networking-stack/

and next is the specific block devices via network:

http://www.mjmwired.net/kernel/Documentation/nbd.txt (which is very
much userspace in fact, and not very helpful as it only effectively
says "nbd works") and the one I found most useful:

http://www.linuxjournal.com/article/3778

http://www.linuxjournal.com/article/8149

http://www.fi.muni.cz/~kripac/orac-nbd/

http://www.thegeekstuff.com/2009/02/nbd-tutorial-network-block-device-jumpstart-guide/

http://www.it.uc3m.es/~ptb/nbd/

(last one being an enhanced nbd internals....)

So....as u can see....lots of resources from different places....no
central resources...learn googling.   But concurrent with that read a
book in depth on Linux kernel internal will be useful.
