Which of the following can be used lo provide storage lo multiple virtual servers through a single interface?

Virtual fabric is a broad concept related to abstracting network components, not a specific technology for multiple virtual servers to share a single physical storage interface.

Virtual storage is a general term referring to the abstraction of physical storage resources, not a specific mechanism for multiple virtual servers sharing a single physical interface.

LVM (Logical Volume Manager) is a system for managing disk space on a single server, allowing flexible allocation of volumes, but it does not facilitate multiple virtual servers sharing a single physical storage interface.

N_Port ID Virtualization (NPIV) is a Fibre Channel feature that allows a single physical HBA port to register multiple N_Port IDs (WWPNs) with a Fibre Channel switch. This enables multiple virtual machines (virtual servers) on a single host to each have their own unique WWPN, allowing them to independently access SAN storage through the host's single physical HBA port.
