NAME: 
          comp.arch.storage

STATUS:
          unmoderated


DESCRIPTION:

	storage system issues, both software and hardware


CHARTER:

To facilitate and encourage communication among people interested in
computer storage systems.  The scope of the discussions would include
issues relevant to all types of computer storage systems, both hardware
and software.  The general emphasis here is on open storage systems as
opposed to platform specific products or proprietary hardware from a
particular vendor.  Such vendor specific discussions might belong in
comp.sys.xxx or comp.periphs.  Many of these questions are at the
research, architectural, and design levels today, but as more general
storage system products enter the market, discussions may expand into
"how to use" type questions.


RATIONALE:

As processors become faster and faster, a major bottleneck in computing
becomes access to storage services:  the hardware - disk, tape,
optical, solid-state disk, robots, etc., and the software - uniform and
convenient access to storage hardware.  A far too true comment is that
"A supercomputer is a machine that converts a compute-bound problem
into an I/O-bound problem."  As supercomputer performance reaches
desktops, we all experience the problems of:

o	hot processor chips strapped onto anemic I/O architectures
o	incompatable storage systems that require expensive systems
	    integration gurus to integrate and maintain
o	databases that are intimately bound into the quirks of an
	    operating system for performance
o	applications that are unable to obtain guarantees on when their
	    data and/or metadata is on stable storage
o	cheap tape libraries and robots that are under-utilized because
	    software for migration and caching to disk is not readily
	    available
o	nightmares in writing portable applications that attempt to
	    access tape volumes

This group will be a forum for discussions on storage topics including
the following:

1)	commercial products - OSF Distributed File System (DFS) based on
	    Andrew, Epoch Infinite Storage Manager and Renaissance,
	    Auspex NS5000 NFS server, Legato PrestoServer, AT&T Veritas,
	    OSF Logical Volume Manager, DISCOS UniTree, etc.
2)	storage strategies from major vendors - IBM System Managed Storage,
	    HP Distributed Information Storage Architecture and StoragePlus,
	    DEC Digital Storage Architecture (DSA), Distributed
	    Heterogeneous Storage Management (DHSM), Hierarchical Storage
	    Controllers, and Mass Storage Control Protocol (MSCP)
3)	IEEE 1244 Storage Systems Standards Working Group
4)	ANSI X3B11.1 and Rock Ridge WORM file system standards groups
5)	emerging standard high-speed (100 MB/sec and up) interconnects to
	    storage systems: HIPPI, Fiber Channel Standard, etc.
6)	POSIX supercomputing and batch committees' work on storage
	    volumes and tape mounts
7)	magnetic tape semantics ("Unix tape support is an oxymoron.")
8)	physical volume management - volume naming, mount semantics,
	    enterprise-wide tracking of cartridges, etc.
9)	models for tape robots and optical jukeboxes - SCSI-2, etc.
10)	designs for direct network-attached storage (storage as black box)
11)	backup and archiving strategies
12)	raw storage services (i.e., raw byte strings) vs. management of
	    structured data types (e.g. directories, database records,...)
13)	storage services for efficient database support
14)	storage server interfaces, e.g., OSF/1 Logical Volume Manager
15)	object server and browser technology, e.g. Berkeley's Sequoia 2000
16)	separation of control and data paths for high performance by
	    removing the control processor from the data path; this
	    eliminates the requirements for expensive I/O-capable
	    (i.e., mainframe) control processors
17)	operating system-independent file system design
18)	SCSI-3 proposal for a flat file system built into the disk drive
19)	client applications which bypass/ignore file systems:
	    virtual memory, databases, mail, hypertext, etc.
20)	layered access to storage services - How low level do we want
	    device control?  How to support sophisticated, high-performance
	    applications that need to bypass the file abstraction?
21)	migration and caching of storage objects in a distributed
	    hierarchy of media types
22)	management of replicated storage objects (differences/similarities
	    to migration?)
23)	optimization of placement of storage objects vs. location
	    transparency and independence
24)	granularity of replication - file system, file, segment, record, ...
25)	storage systems management - What information does an administrator
	    need to manage a large, distributed storage system?
26)	security issues - Who do you trust when your storage is
	    directly networked?
27)	RAID array architectures, including RADD (Redundant Arrays
	    of Distributed Disks) and Berkeley RAID-II HIPPI systems
28)	architectures and problems for tape arrays - striped tape systems
29)	stable storage algorithm of Lampson and Sturgis for critical metadata
30)	How can cheap MIPS and RAM help storage? -  HP DataMesh, write-only
	    disk caches, non-volatile caches, etc.
31)	support for multi-media or integrated digital continuous media
	    (audio, video, other realtime data streams)

This group will serve as a forum for the discussion of issues which do
not easily fit into the more tightly focused discussions in various
existing newsgroups.  The issues are much broader than Unix
(comp.unix.*, comp.os.*), as they transcend operating systems in
general.  Distributed computer systems of the future will offer
standard network storage services; what operating system(s) they use
(if any) will be irrelevant to their clients.  The peripheral groups
(comp.periphs, comp.periphs.scsi) are too hardware oriented for these
topics.  Several of these topics involve active standards groups but
several storage system issues are research topics in distributed
systems.  In general, the standards newsgroups (comp.std.xxx) are too
narrowly focused for these discussions.

VOTES:

ONLY VOTES RECEIVED BY APRIL 10, 23:59 CDT WILL BE COUNTED

TO VOTE YES: send mail to [email protected] with the words "YES" and
"comp.arch.storage" in the subject line (preferred) or message body
(acceptable)

TO VOTE NO: send mail to [email protected] with the words "NO" and
"comp.arch.storage" in the subject line (preferred) or message body
(acceptable)

Only votes mailed to the above addresses will be counted.  In
particular, votes mailed to me directly or through replying to this
posting will not be counted.  Ambiguous votes or votes with
qualifications ("I would vote yes for comp.arch.storage provided
that...") will not be counted.  In the case of multiple votes from a
given person, only the last will be counted.

This Call For Votes, along with acknowledgements of votes received will 
be posted several times throughout the voting period.

comp.storage - Request for New Group Discussion

As processors become faster and faster, a major bottleneck in computing
becomes access to storage services:  the hardware - disk, tape, optical,
solid-state disk, robots, etc., and the software - uniform and
convenient access to storage hardware.  A far too true comment is that
"A supercomputer is a machine that converts a compute-bound problem into
an I/O-bound problem."  As supercomputer performance reaches desktops, we
all experience the problems of:

o	hot processor chips strapped onto anemic I/O architectures
o	incompatable storage systems that require expensive systems
	    integration gurus to integrate and maintain
o	databases that are intimately bound into the quirks of an
	    operating system for performance
o	applications that are unable to obtain guarantees on when their
	    data and/or metadata is on stable storage
o	cheap tape libraries and robots that are under-utilized because
	    software for migration and caching to disk is not readily
	    available
o	nightmares in writing portable applications that attempt to
	    access tape volumes

This newsgroup would be a forum for discussions on storage topics including
the following:

1)	commercial products - OSF Distributed File System (DFS) based on
	    Andrew, Epoch Infinite Storage Manager and Renaissance,
	    Auspex NS5000 NFS server, Legato PrestoServer, AT&T Veritas,
	    OSF Logical Volume Manager, DISCOS UniTree, etc.
2)	storage strategies from major vendors - IBM System Managed Storage,
	    HP Distributed Information Storage Architecture and StoragePlus,
	    DEC Digital Storage Architecture (DSA), Distributed
	    Heterogeneous Storage Management (DHSM), Hierarchical Storage
	    Controllers, and Mass Storage Control Protocol (MSCP)
3)	IEEE 1244 Storage Systems Standards working group
4)	ANSI X3B11.1 and Rock Ridge WORM filesystem standards groups
5)	emerging standard high-speed (100 MB/sec and up) interconnects to
	    storage systems: HIPPI, Fiber Channel Standard, etc.
6)	POSIX supercomputing and batch committees' work on storage
	    volumes and tape mounts
7)	magnetic tape semantics ("Unix tape support is an oxymoron.")
8)	physical volume management - volume naming, mount semantics,
	    enterprise-wide tracking of cartridges, etc.
9)	models for tape robots and optical jukeboxes - SCSI-2, etc.
10)	designs for direct network-attached storage (storage as black box)
11)	backup and archiving strategies
12)	raw storage services (i.e., raw byte strings) vs. management of
	    structured data types (e.g. directories, database records,...)
13)	storage services for efficient database support
14)	storage server interfaces, e.g., OSF/1 Logical Volume Manager
15)	object server and browser technology, e.g. Berkeley's Sequoia 2000
16)	separation of control and data paths for high performance by
	    removing the control processor from the data path; this
	    eliminates the requirements for expensive I/O-capable
	    (i.e., mainframe) control processors
17)	operating system-independent filesystem design
18)	SCSI-3 proposal for a flat filesystem built into the disk drive
19)	client applications which bypass/ignore filesystems:
	    virtual memory, databases, mail, hypertext, etc.
20)	layered access to storage services - How low level do we want
	    device control?  How to support sophisticated, high-performance
	    applications that need to bypass the file abstraction?
21)	migration and caching of storage objects in a distributed
	    hierarchy of media types
22)	management of replicated storage objects (differences/similarities
	    to migration?)
23)	optimization of placement of storage objects vs. location
	    transparency and independence
24)	granularity of replication - filesystem, file, segment, record, ...
25)	storage systems management - What information does an administrator
	    need to manage a large, distributed storage system?
26)	security issues - Who do you trust when your storage is
	    directly networked?
27)	RAID array architectures, including RADD (Redundant Arrays
	    of Distributed Disks) and Berkeley RAID-II HIPPI systems
28)	architectures and problems for tape arrays - striped tape systems
29)	stable storage algorithm of Lampson and Sturgis for critical metadata
30)	How can cheap MIPS and RAM help storage? -  HP DataMesh, write-only
	    disk caches, non-volatile caches, etc.
31)	support for multi-media or integrated digital continuous media
	    (audio, video, other realtime data streams)

The current Usenet hierarchy has no central place for these discussions.
The issues are much broader than Unix (comp.unix.*, comp.os.*), as they
transcend operating systems in general.  The peripheral groups
(comp.periphs, comp.periphs.scsi) are much too hardware oriented for
these topics.  Distributed computer systems of the future will offer
standard network storage services; what operating system(s) they use (if
any) will be irrelevant to their clients.  The architecture and
massively parallel computing groups (comp.arch, comp.parallel) are also
inappropriate.  [Of course, Usenet should have a comp.distributed
newsgroup, but that is for another time.]  Several of these topics
involve active standards groups but some of the standards aspects are
research topics in distributed systems.  Real products are evolving at a
furious rate, and commercial activity may outpace some standards efforts
underway.

I envision this group as being unmoderated.

CALL FOR VOTES TO CREATE NEWSGROUP
----------------------------------

NAME: 
          comp.arch.storage

STATUS:
          unmoderated


DESCRIPTION:

	storage system issues, both software and hardware


CHARTER:

To facilitate and encourage communication among people interested in
computer storage systems.  The scope of the discussions would include
issues relevant to all types of computer storage systems, both hardware
and software.  The general emphasis here is on open storage systems as
opposed to platform specific products or proprietary hardware from a
particular vendor.  Such vendor specific discussions might belong in
comp.sys.xxx or comp.periphs.  Many of these questions are at the
research, architectural, and design levels today, but as more general
storage system products enter the market, discussions may expand into
"how to use" type questions.


RATIONALE:

As processors become faster and faster, a major bottleneck in computing
becomes access to storage services:  the hardware - disk, tape,
optical, solid-state disk, robots, etc., and the software - uniform and
convenient access to storage hardware.  A far too true comment is that

	    data and/or metadata is on stable storage

This group will serve as a forum for the discussion of issues which do
not easily fit into the more tightly focused discussions in various
existing newsgroups.  The issues are much broader than Unix
(comp.unix.*, comp.os.*), as they transcend operating systems in
general.  Distributed computer systems of the future will offer
standard network storage services; what operating system(s) they use
(if any) will be irrelevant to their clients.  The peripheral groups
(comp.periphs, comp.periphs.scsi) are too hardware oriented for these
topics.  Several of these topics involve active standards groups but
several storage system issues are research topics in distributed
systems.  In general, the standards newsgroups (comp.std.xxx) are too
narrowly focused for these discussions.
