I think the source code is the best we've got atm. I recommend looking at o=
ne of the simpler SRs first e.g.
 DummySR: this is a "pretend" SR, used for testing
 udevSR: represents block devices hotplugged into the host ('xe vdi-introdu=
ce' 'xe vdi-forget' are called from udev scripts)
and then maybe extSR: vhds on local storage.

Cheers,
Dave
