I have read on the internet about the difference between NAS and SAN:http://www.nas-san.com/differ.html
but I need some explanations from an expert who used both NAS and SAN.
what I understand is:
NAS: we can use a swicth and connect multiple servers then connect the NAS Head to the switch then NAS Head to disk array or tapes. but I don't know what is the NAS Head, is there any specific software to add?
SAN:connect all servers through fiber channel to a fiber channel switch then to the disk array or tape device. is there any software to install?
