Explanation

iSCSI (Internet Small Computer Systems Interface) encapsulates SCSI commands inside TCP/IP packets, enabling block-level storage access over standard Ethernet networks. This allows organizations to build a Storage Area Network (SAN)-like infrastructure without requiring dedicated Fibre Channel hardware, making it a cost-effective alternative. SCSI is the underlying command protocol but operates over direct-attached or Fibre Channel connections, not TCP/IP. SATA is a physical interface standard for connecting storage devices locally. TLS (Transport Layer Security) is a cryptographic protocol for securing communications and is unrelated to storage protocols.
