plz google this are basic technical question not the ones where you need to apply mind. I hope this will be good for you rather than giving you the answer. Or if possible explain your logic why you find it same. i can answer you on that.

Yes SAN only HDD are used of one type and not multiple type whereas HSM involves multiple medias...Ok i think you are thinking today's SAN also offers feature of moving less accessed data to lower cost disk.....But remember SAN is for less data...HSM is like archieve of data with current data in primary storage(which can be SAN)
