Why each option
To create multiple isolated logical fabrics within a single physical Fibre Channel infrastructure, the Virtual Fabric feature is used.
NPIV (N_Port ID Virtualization) allows a single physical HBA port to register multiple N_Port IDs with the fabric, primarily for virtualization, but it does not create separate logical fabrics.
Virtual Fabrics, also known as logical switches or VSANs (Virtual Storage Area Networks), allow a single physical Fibre Channel switch or infrastructure to be partitioned into multiple isolated logical fabrics, enabling consolidation while maintaining separation for different server groups or applications.
Zoning is a security mechanism that restricts communication between devices within a single fabric, defining which devices can see each other, but it does not create distinct logical fabrics.
Segmentation is a general networking term for dividing networks; however, in Fibre Channel, 'Virtual Fabric' or 'VSAN' is the specific feature for implementing isolated logical fabrics on shared physical hardware.
