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.

A SAN is any network used to connect block storage to hosts. Types include FC-SW, FC-AL, FCoE, and iSCSI.

A fabric is usually referring to a specific type of SAN physical topology, generally FC-SW.

So can we say that A fabric is also a SAN or A SAN is also a fabric.
The defination of fabric is the interconnection between the nodes. So where's the difference with SAN ?
