A SAN is a term to describe any block storage network. A fabric is a term to describe a specific type of block storage network.  SANs are fabrics when they are using FC-SW or FCoE as the physical link. SANs are not fabrics when are using FC-AL or iSCSI as the physical link.
What is the difference between a fabric and SAN ? I am bit confused about both the terminologies. Can someone please explain in simple words.Thanks in advance.
