Internet SCSI Protocol (iSCSI)

Internet SCSI (iSCSI) is a simple, yet powerful idea that will change the way we think about computer storage and the way it relates to computer networks. The iSCSI protocol maps the SCSI remote procedure invocation model on top of the Internet's.

Transport Control Protocol (TCP) to produce a transport mechanism for storage over Ethernet. In other words, iSCSI encapsulates SCSI commands into TCP packets ; thus enabling the transport of I/O block data over IP networks. Building on the heritage of SCSI and Ethernet, iSCSI enables a new world where storage area networks using Ethernet are possible. It also enables remote mirroring, remote backup and true disaster recovery.
