Abstract

This document specifies the requirements iSCSI and its related infrastructure should satisfy and the design considerations guiding the iSCSI protocol development efforts. In the interest of timely adoption of the iSCSI protocol, the IPS group has chosen to focus the first version of the protocol to work with the existing SCSI architecture and commands, and the existing TCP/IP transport layer. Both these protocols are widely-deployed and well-understood. The thought is that using these mature protocols will entail a minimum of new invention, the most rapid possible adoption, and the greatest compatibility with Internet architecture, protocols, and equipment.
