Internet Small Computer Systems Interface or Internet SCSI (iSCSI) is a network protocol standard, officially ratified by the Internet Engineering Task Force, that allows the use of the SCSI protocol over TCP/IP networks. SCSI is a popular family of protocols that enable systems to communicate with I/O devices, especially storage devices. iSCSI is a transport layer protocol in the SCSI-3 specifications framework. Acceptance of iSCSI in corporate production environments has accelerated now that gigabit ethernet is becoming more common. Building iSCSI-based storage area networks (SAN) has become an alternative to creating Fibre Channel-based SANs.
