Scsi is not a good place to start your kernel experience. Anyway, within the scsi stack you have: scsi parallel sas (serial attached scsi) usb (transports scsi commands if you did not know. Then a SAT chip converts it to ATA typically.) iScsi (no hardware needed, so this might be a good place to start experimenting) FCoE (Requires a FC switch, so this is expensive) and even libata (for sata drivers) is currently a scsi subsystem And I'm sure I missed a few. I assume you are interested in writing a scsi parallel driver? That is dying technology I believe. The future is SAS, but parallel might be a good starting point. I really don't know how I would go about learning the scsi stack.
