I am writing a diploma thesis (or whatever it is called in english) on the subject of computer storage systems. This subject, obviously, has nothing to do with electronics (I was forced, due to circumstances, to take this subject).
I have wrote a lot on this subject (history of storage systems, history of storage media, types of storage media, RAID, IBM FlashSystem 720 and 820 (which is the specific storage system that I have to describe in detail) but I did not write anything about types of computer data storage systems. And what computer storage systems actualy are (like an introduction. I mean, I know what they are in general, but I don't know how to put it on writing), accept what I have wrote in the history section.
So, can you provide me with a literature that describes computer data storage systems in general, tell me what types of storage systems exist (DAS, NAS, SAN, CAS, COS...?)? Also, their application (servers,...?).
IBM FlashSystem 720 and 820:
