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).
