1. Introduction
The IP Storage Working group is chartered with developing
comprehensive technology to transport block storage data over IP
protocols. This effort includes a protocol to transport the Small
Computer Systems Interface (SCSI) protocol over the Internet (iSCSI).
The initial version of the iSCSI protocol will define a mapping of
SCSI transport protocol over TCP/IP so that SCSI storage controllers
(principally disk and tape arrays and libraries) can be attached to
IP networks, notably Gigabit Ethernet (GbE) and 10 Gigabit Ethernet
(10 GbE).
