years ago that was, eh?). Granted, this was with Linux, which used a simple
FIFO for issuing SCSI commands...
Windows too.
If the LUN does not support tagged queue - then the requests for it are in the
single queue indexed by the block number.
Tape I/O is also zero-copy in Windows, and so is disk file IO if the file is
opened as noncached.
