I think we have a case of overlapping vocabulary from two different domains. Per SCSI Architecture Model (SAM-2, SAM-3), iSCSI is very clearly a "SCSI transport protocol" (as opposed to a SCSI application layer protocol). Parallel SCSI, Fibre Channel etc. are all "SCSI transports" per SCSI conventions. That is all the critiqued abstract is trying to describe. -- Mallikarjun Mallikarjun Chadalapaka Networked Storage Architecture Network Storage Solutions Hewlett-Packard MS 5668 Roseville CA 95747 [EMAIL PROTECTED] ----- Original Message ----- From: "Bob Braden" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Tuesday, February 11, 2003 3:48 PM Subject: Re: Protocol Action: iSCSI to Proposed Standard > > *> > *> The IESG has approved publishing the following Internet-Draft > *> as a Proposed Standard: > *> > *> o iSCSI <draft-ietf-ips-iscsi-20.txt> > *> > *> This document is the product of the IP Storage Working Group. > *> > *> The IESG contact persons are Allison Mankin and Scott Bradner. > *> > *> > *> Technical Summary > *> > *> The Small Computer Systems Interface (SCSI) is a family of > *> protocols for communicating with I/O devices, especially storage > *> devices.
