What are the storage area networks types?

Basically SAN has two types FC (fiber channel) and ISCSI.
Some storages are hybrid and my act as FC and ISCI simultaneously.

There are two broad types of storage networks - NAS and SAN.
NAS is file-level access which includes CIFS and NFS protocols.
SAN on the other hand is referred to block-level access which works on protocols such as FC, iSCSI, or the new FCoE.
