iSCSI

iSCSI, or Internet Small Computer System Interface, is a protocol that facilitates the transport of block-level storage data over a TCP/IP network. It enables storage devices, often referred to as targets, to be accessed remotely by servers or clients, known as initiators.

iSCSI offers a cost-effective alternative to traditional Fibre Channel, allowing organizations to leverage existing Ethernet infrastructure for storage communication. By encapsulating SCSI commands within IP packets, iSCSI enables efficient and reliable storage communication across local or wide-area networks. This technology finds applications in data centers, storage virtualization, and remote backups, offering a flexible and scalable solution for managing storage resources.
