Which IP storage is supported on vSphere?

SCSI (Small Computer System Interface) is a standard for physically connecting and transferring data between computers and peripheral devices, but it is not an IP-based storage protocol itself; iSCSI encapsulates SCSI commands over IP.

vSAN is VMware's software-defined storage solution that pools direct-attached storage from hosts into a single datastore, but it is not an IP storage protocol in the same category as iSCSI.

SAN (Storage Area Network) is a general term for a dedicated network that provides access to consolidated, block-level data storage, and while iSCSI can be used in a SAN, SAN itself is not a specific IP storage protocol.

iSCSI (Internet Small Computer System Interface) is an IP-based storage networking protocol that enables vSphere hosts to connect to remote storage arrays using standard Ethernet network adapters. It provides block-level access to storage by encapsulating SCSI commands over TCP/IP.
