Re: BOF Request

[Costa Sapuntzakis <csapuntz@cisco.com>]

Hi,

I'm working with Andy Bechtolsheim on the IP SAN initiative at Cisco.
I believe we (the industry) are behind at this point because we
(Cisco) have been hearing from our customers (and I'm sure you've been
hearing from yours) that they want these technologies now. As such,
much of the discussion on the charter and goals should happen before
the BOF (on the ips mailing list).

Let's make the IETF meeting be for serious high-bandwidth engineering
discussion of the various approaches so we can attempt to reach
consensus on a technical direction.

Proposed agenda for BOF:

> 5 min Review of BOF agenda and objectives (D. Lee/M. Bradley)
> 10 min IP Storage Goals (D. Nagle/A. Wilson)
> 15 min Discussion
> 30 min Approaches & Implementations (10 min presentations)
> o SCSI/TCP (TBA)
> o Adaptec (A. Wilson)
> o ISI's NetSCSI (?)
> 40 min discussion
> 5 min Proposed charters (D. Lee/M. Bradley/C. Sapuntzakis)
> 15 min Discussion

Our formal interaction with T10 and T11 should be minimized. The IETF
strongly discourages the republishing of IETF standards by other
organizations. In addition, IETF can work much more quickly than
ANSI standards organizations.

The only interaction I see with T13 is if we define an IDE transport protocol.
ATAPI command sets are now handled through T10.

FCP is an impressive protocol, especially in the bulk of documentation
required to understand it. It is very much tied to Fibre Channel
Physical Layer. Understanding FCP, its limitations, how it and its
associated discovery mechanisms need to be fixed up to work in an IP
environment is a large undertaking. FCP will seriously slow down the
generation of any standard and impede the clarity of the final
standard.


A proposed charter:
-------------------

Description of Working Group:

The goal of this working group is to define extensions to current IETF
transports for storage networking.

There are a several areas to consider:

    - Reducing protocol processing overhead at servers and clients
    - SCSI transport on top of TCP
    - QoS parameters for storage networks
    - Running storage transports at multi-gigabit speeds

The objectives of this working group are:

* A proposed standard for a SCSI transport on top of TCP

* A proposed standard for extensions to TCP that reduce protocol
processing overhead.

* Produce an informational RFC describing the QoS requirements of storage
networks. Propose QoS extensions to diffserv if necessary.

* Produce an informational RFC discussing the issues behind running
storage transports at multi-gigabit speeds.
