iSCSI is a protocol that allows for the transmission and use of SCSI commands and features over a TCP-based network.
iSCSI allows systems to use block-level storage that looks and behaves as a SAN would with physical servers, but to leverage the TCP network within a virtualized environment and cloud.
The protocol that allows a system to use block-level storage as if it were a Storage Area Network (SAN) but over TCP network traffic instead is iSCSI.
iSCSI stands for Internet Small Computer System Interface, and it is a protocol that enables block-level storage access over IP networks. It allows a host computer to send SCSI commands over a TCP/IP network to a remote storage device, making it possible to use Ethernet as the transport medium for storage traffic instead of a dedicated Fibre Channel (FC) network.
With iSCSI, a host computer can access a remote storage device, typically a SAN, as if it were a local storage device. The storage device can be located anywhere on the network, and the host can access it over a standard Ethernet connection.
SATA, which stands for Serial Advanced Technology Attachment, is a protocol used for connecting hard drives and solid-state drives (SSDs) to a computer's motherboard. It is not used for network storage access.
TLS, which stands for Transport Layer Security, is a protocol used for securing network communications. While it is an important security protocol, it is not used for storage access.
SCSI, which stands for Small Computer System Interface, is a protocol used for connecting peripheral devices, such as hard drives, printers, and scanners, to a computer. While it is related to iSCSI, it is not used for storage access over a network.
