Abstract
Internet Small
Computer System Interface (iSCSI) is a proposed
transport protocol for Small Computer
Systems Interface (SCSI) that
operates on top of TCP. This memo describes a standard mechanism for
enabling clients to bootstrap
themselves using the iSCSI protocol.
The goal of this standard is to enable
iSCSI boot clients to obtain
the information to open an iSCSI
session with the iSCSI boot server.
1. Introduction
The Small
Computer Systems Interface (SCSI) is a popular family of
protocols for communicating with I/O
devices, especially storage
devices. SCSI can be characterized as a
request/response messaging
protocol with a standard architecture
and componentized command sets
for different device classes.
iSCSI is a
proposed transport protocol for SCSI that operates on top
of TCP. The role of iSCSI is necessitated by the
evolution of the
system interconnect from a shared bus
to a switched network. IP
networks meet the architectural and
performance requirements of
transporting SCSI, paving the way for
the iSCSI protocol.

Bootstrapping September 2005
Many diskless clients sometimes
bootstrap off remote SCSI devices.
Such diskless entities are
lightweight, space efficient, and power-
conserving and are increasingly
popular in various environments.
