TRANSCRIPT
Topics
• Introduction to INCITS– Principles– Background– Storage-related Committees & Workgroups– Procedures
• History• Cooperative Strategy• Near-term objectives
INCITS
• International Committee for Information Technology Standardization– Called X3 for many years up to 1998– Had to change because of “web search
problem”– Holds the US TAG for several key ISO
groups
• See www.incits.org for details
INCITS is Fully open!!
• Anyone can attend INCITS meetings @ no charge
• Organizational memberships necessary to vote at some Plenary meetings– $800/year/organization
• ANSI Patent Policy applies:– Reasonable, non-discriminatory– See www.ansi.org
• All drafts and proposals available on public web sites
INCITS
• Formal standards developer accredited by ANSI, covering:– Programming languages (Fortran, C,
Pascal, C++ etc.)– Magnetic & optical media and formats– Real time location systems & RFID
technology– Biometrics– Storage interfaces & command sets ……
Storage Interface Committees
• First formed pre-1977• Splits occurred in 1982 & 1995• The committee names all changed in 1993 as
well• Now 3 active groups – T10, T11, T13
– See http://www.t10.org etc.
• Nearly all widely-used storage peripheral interfaces for last 20 years defined by these committees
INCITS Standards
T10T10 T11T11 T13T13
SCSI commands
(disk, tape, mmc)
SCSI parallel
SAS
FIPS 60
(block mux)
IPI
HIPPI Parallel
HIPPI Serial
Fibre Channel
ATA
(now @ 7th gen)
ATAPI
INCITS Procedures
• Policies and Procedures defined in RD-2– Covers both
• Standards (equivalent to standards track)• Technical Reports (equivalent to informational)
– Includes both:• Committee Letter Ballots (equivalent to Last Call)• Public Review (administered by ANSI)
• Have to have a Project Proposal approved by committee before beginning work– One standard/TR per project
History
• Existing storage-related documents:– RFC2834 ARP and IP Broadcast over HIPPI-800.
J.-M. Pittet. May 2000. (Format: TXT=76243 bytes) (Obsoletes RFC1374) (Status: PROPOSED STANDARD)
– RFC2835 IP and ARP over HIPPI-6400 (GSN). J.-M. Pittet. May 2000. (Format: TXT=74178 bytes) (Status: PROPOSED STANDARD)
– RFC2625 IP and ARP over Fibre Channel. M. Rajagopal, R. Bhagwat, W. Rickard. June 1999. (Format: TXT=137741 bytes) (Status: PROPOSED STANDARD)
Approach
• Existing storage-related MIBs– RFC2837 Definitions of Managed Objects
for the Fabric Element in Fibre Channel Standard. K. Teow. May 2000. (Format: TXT=87860 bytes) (Status: PROPOSED STANDARD)
• FC Management MIB being created by IP Storage WG as a replacement, see:– http://www.ietf.org/internet-drafts/draft-ietf-ips-fcmgmt-mib-04.txt
Approach
– Other MIBs have been either I-Ds or private documents
• e.g. FA-MIB – Documented after widespread use by T11 as service
to industry only (see http://www.t11.org/t11/docreg.nsf/ldraftl/mib-fa)
» Includes indication that new developments should use FC Management MIB
• Not well coordinated with T11 projects• Have not followed IETF practices and
approaches
Cooperative Strategy
• Intend is to coordinate activities between INCITS & IMSS to:– Ensure timeliness wrt other work– Follow latest IETF directions, take advantage of
expertise
• T11.5 has approved a process for this:– Run an internal project as usual, including Letter
Ballot, on a draft MIB– When all issues that can be resolved are done,
transfer change control to IMSS
Near-term objectives
• Three MIBs– FC Domain manager– FC Name Server– FC Extensions to Interfaces MIB
• Project Proposals will be voted on by T11.5 in December– Schedule to transfer to IMSS late summer
