`Wireless 'net access spreads
`
`Dial-up service said

`
`WIRELESS ACCESS to the Inter-
`net is becoming more widely
`available for inobile users and
`
`Lonipanies.
`The current wave of services
`olFers wireless access at dial-up
`speeds and will be followed later
`this year by high-speed services.
`Tlie technology was designed

`'net outsourcing
`
`a risky proposition
`
`By Gary H. Anthes
`
`YOU JUMPED ON the Outsourc-
`ing bandwagon long ago. farm-
`ing out data center manage-
`ment, telecommunications, di-
`saster recovery, legacy systems
`maintenance and a few other
`
`things.
`Now you're getting into tlie
`Internet game, so you might
`send
`out
`the
`well
`that
`
`as
`
`door as well, right?
`Not so fast, some users and
`outsourcing experts say. There
`are things about the Internet
`that make outsourcing difficult
`and risky: The technology is
`changing at an explosive rale,
`the direction of emerging mar-
`kets is unclear, and your compa-
`ny's strategy for electronic com-
`merce may not be well-defined.

`
`If the world's most powerful military force
`can't keep hackers out of its
`computer systems, who can? The
`consensus seems to be nobody. But
`there are steps the mihtary — and the
`private sector — can take to reduce the

`risks (see story, page 6).

`'Virtual tape' crams in
`
`data, cuts storage costs
`
`By Tim Oueliettc
`
`DATA CENTER tnanagers soon
`will be able to pack data more ef-
`ficiently into tape systems, sav-
`ing floor space and storage bud-
`gets in the process.
`High-end tape storage com-
`petitors IBM and Storage Tech-
`are developing
`nology Corp.
`"virtual tape" products, which
`are supposed to
`stop users
`from worrying about how much
`data is in each tape cartridge.
`Products won't appear until the
`summer.
`Virtual tape technology com-
`pletely fills each tape cartridge
`
`Currently,
`tape
`in
`a
`library.
`users might fill only a small por-
`tion of each tape because of vol-
`ume constraints-
`More efficient use of tape
`storage means users can reduce
`the number of new tape car-
`tridges, drives and libraries they
`need to fijlfill rising storage re-
`quirements.
`"This is exactly what we need
`to save space on the library

`Archibald,
`said

`while storing more data, but
`tape systems haven't kept up.
`even though more data — three
`times more, according to some
`industry estimates — is stored
`on tape than on disk, analysts
`
`said.
`IBM's Virtual Tape Server
`(VTS), due to ship in June, will
`be the first product to address
`
`that issue. StorageTek's Virtual
`Storage Manager (VSM) won't
`be available until next year (see
`
`chart).
`Both products wiU use disk
`arrays to cache mainframe data
`before moving it to tape. But the
`mainframe will see the disk ar-
`ray as a typical tape library.
`IBM's VTS systems use a
`hardware controller that can
`reside on IBM's 3494 Magstar
`libraries and don't

`Today's tape storage manage-
`ment is too manual-intensive,
`which makes it more expensive,
`Archibald said.
`IBM and research firm Inter-
`national Data Corp. in Framing-
`ham. Mass.. estimate that only
`about 10% of each data center's
`tape cartridge is filled with data.

`umes can vary in size, they take

`
`Info flap" NT 5.0 rates a thumbs-up
`
`Last week I had a harrowing introduction to the power
`
`of the Internet to spread misinformation.
`It started on a Sunday, when a senior Oracle execu-
`tive read a Computerworld article that was sent to him
`by an electronic news service. The article was a glowing en-
`dorsement of Oracle's Universal Server
`
`strategy.
`
`Pleased with the positive publicity, the
`executive forwarded the article to other
`
`executives at Oracle. They, in turn, sent it
`to Oracle's marketing and salespeople
`around the world.
`By midweek, hundreds, perhaps thou-
`sands of Oracle employees had seen the
`article. So had their customers. Calls were
`coming in to our editorial office from cus-
`tomers wanting to know if the story was true.
`It wasn't.
`At least, not the way it was presented. The article had ap-
`peared as part of a Computerworld Sound Offdebate under
`the byline of Jerry Held, an Oracle senior vice president. It
`was balanced with an opposing opinion from an Informix
`official. Somewhere in the translation from print to electrons,
`the bylines were snipped, and Oracle's opinion looked like
`ouropinion.
`Oracle sent out a clarification, Informix got a letter from us,
`and I earned a few more gray hairs. But I also learned the hard
`way about the power of the Internet to deceive.
`Nearly all our communications these days are digitized at
`some stage. Once information is digital, it can be copied, edit-
`ed and distributed globally at the touch of a button. The Inter-
`net can be a wondrous publishing tool. But it can also be like
`the kids' game of telephone, in which a message is mangled as
`it's whispered from player to player.
`Global E-mail is like publishing, but without the editors. And
`yes, there are reasons we have editors.

`newfeatures of
`Active Directory
`
`By Laura DiDio
`
`ALPHA TESTERS are lauding
`the increased functionality in
`the forthcoming Windows NT
`5.0 and its new Active Directory.
`This is despite the fact that they
`won't get their hands on the
`product until the middle of next
`year (see story at right).
`Unlike the upgrade from NT
`3.51 to NT 4.0. in which the
`main new feature was the Win-
`dows 95 user interface, Win-
`dows NT 5.0 will provide busi-
`nesses with a slew of advanced
`functions. Those include the
`Directory, which will
`Active
`of
`eliminate
`the
`limitations
`the Domain directory and deliv-
`er a true enterprise database
`with centralized management:
`and
`caching
`support;
`
`lava
`
`capabilities.
`
`EASE OF USE CITED
`Among the dozen enterprise us-
`ers polled by Computerworld was
`Ron Milione, chief of technol-
`Systems
`ogy
`Integrated
`at
`Group in Hauppauge, N.Y., who
`called NT 5.0's ease of use and
`setup straightforward.
`"Windows NT 5.0 gives me
`the ability to define users by
`
`their roles in the organization,"
`Milione said. For example. NT
`;.o contains a facility, called the
`Real World User Manager Utili-
`ty, that lets administrators estab-
`lish guest user accounts and as-
`sign that person to a specific
`group. "It means I no longer
`have to manually assign user ac-
`cess rights, which is a big time-
`saver." Milione said.
`Jeff Dazell. LAN administra-
`tor for network services for cor-
`porate support at Dana Corp.. a
`automotive
`$7
`parts
`billion
`manufacturer in Toledo. Ohio,
`said he looks forward to the
`availability of the Active Directo-
`ry and Lightweight Directory
`Access Protocol support. Both
`of these features will improve
`management capabilities and
`Internet access for his 45.000
`end users.
`Dana has 2) NT 3.51 and 4.0
`domains, and the naming con-
`ventions are different for each
`one. "I have no way of knowing
`where a particular database or
`CPU resides. The Active Direc-
`tory will solve that." Dazell said.
`But the alpha testers also re-
`
`JlsersLDelayiiQDOilnews
`
`Microsoft's decision to delay Windows NT S-O until the summer of
`1998 comes as a welcome relief to 11 NT users contacted by Com-
`puterworld last week.
`The users said the respite will provide the breathing space need-
`ed to complete installation of NT 4.0 and related hardware up-
`grades. It will also give Microsoft the time to get Windows NT j.o
`right the first time.
`"If Windows NT 5.0 is stable, I want It. But I don't want an oper-
`ating system that's broken or half-baked," said Kurt Guerrero, net-
`work administrator at Northern Trust Co. in Chicago. "It gives me
`a real laugh that Microsoft is now just shipping a beta release of
`the Windows NT 4.0 Service Pack 3 software patch. What does
`that tell you?" he said.
`Richard Palmer, a programmer at Texas Instruments, said the
`chip maker is riding the fence with respect to Its NT 5.0 migration.
`"It will cost us $100 to S200 per workstation license for our
`30,000 workstations worldwide. That's millions of dollars in up-
`grade costs and over a year to upgrade. When we look at it that
`way, we don't mind living with the domain directory and the older
`versions of Windows NT for another year," Palmer said.
`Dan Schuffert, lead senior systems programmer at a Chicago
`paper manufacturing firm with 40,000 users worldwide, agreed.
`"I'll welcome Windows NT 5.0, but I won't be the first one to in-
`stall it because Microsoft has a nasty habit of using its consumers
`as the test bed," he said. — Laura DiOio
`
`a red alert.
`"There are definite glitches in
`|NT 5.0] synchronization during
`peak usage time and across the
`WAN links. We've experienced
`time-outs." Milione said.
`Dazell said problems with
`repUcation and synchronization
`are "showstoppers" that could
`make network operations grind
`to a halt. But he said he would
`prefer that Microsoft hold up
`the release of Windows NT 5.0
`for a year to get it right. " Better
`that than having to release five
`service packs to fix the bugs." he
`
`said.
`Richard Palmer, a program-
`mer at Texas Instruments, Inc.
`in Dallas, said he is resigned to
`the fact that he won't get NT 5.0
`for more than a year Mean-
`while, the chip maker is con-
`workarounds
`structing
`that
`make the Domain directory eas-
`ier to live with. O
`
`Inteqrated's Ron Milione:
`Windows NT 5.0 upgrade will
`be "a big tlme-savcr"
`
`ported a major flaw in the pre-
`release software. The synchroni-
`zarion and replication feature
`
`that controls server o[>erations
`doesn't work properly. Without
`complete synchronization, us-
`ers on a Windows NT 5.0 net-
`work could be denied access to
`key resources and find them-
`selves unable to communicate
`with other users.

`
`AMD challenges Intel
`with cheaper MMX chip
`
`Court says Intel can't
`claim MMX term
`
`By April Jacobs
`
`ANALYSTS SAY end users won't
`be able to tell the difTerciicc be-
`tween AMD Corp.'s K6 MMX
`processor, which sliippcd last
`week, and archrival Intel Corp.'s
`Pentium Pro chip.
`Except, that is, for the price.
`AMD said it plans to price its
`chips at least 25% below compa-
`rable Intel offerings (see chart).
`AMD's K6 MMX is available
`in speeds of 233, 200 and 166
`MHz. Intel
`Santa
`in
`Clara,
`Calif, hasn't yet announced a
`233-MHz chip.
`AMD's K6 MMX is compati-
`ble with Microsoft Corp 's Win-
`dows 95. Windows NT and Win-
`dows 3.x; Novell, Inc. s NetWare:

`
`Users who plan to use mes-
`saging middleware will get a
`glimpse of new management
`tools this week at the first
`MQSeries Technical Confer-
`ence in San Francisco.
`Messaging
`middleware,
`such as IBM's MQSeries, lets
`multiple applications on dif-
`
`ferent platforms share data
`through the use of secure,
`asynchronous data messages
`held in queues.
`But there is still a need for
`configuration and manage-
`ment tools. Leading systems
`management vendors are ad-
`dressing that need.
`Candle Corp. in Santa Mon-
`ica, Calif., will announce Ver-
`sion 2.0 of its Command Cen-
`MQSeries
`monitoring
`ter
`software and a new MQSeries
`configuration tool.
`Boole & Babbage, Inc in
`San jose, Calif, will announce
`availability of AutoOperator
`for MQSeries, which centrally
`manages message queues,
`along with plans to provide a
`new Windows interface.

`AMD from using the term
`MMX with the K6.
`"Intel thought they could .

`
`OBJECT DESIGN, INC. plans
`this week to release an updated
`version of its market-leading
`object database that lets users
`
`tap in to |ava.
`ObjectStore 5.0 adds support
`
`for storing native Java objects
`and for converting C++ server
`code into client-level |ava.
`prospective
`Several
`
`buyers
`said the Java capabihties should
`up
`speed
`application
`their
`development chores and make
`ObjectStore more user-thendly
`at the client end.
`Java is a welcome relief from
`C++, said Dan Woods, a senior
`manager of appUcations devel-
`opment at Time, Inc.'s new-
`media unit in New York. "With
`Java, you're not hamstrung by
`all the ways you can shoot your-
`that C++
`the
`foot
`self
`in
`presents," he said.
`Time uses ObjectStore to run
`a personalized news service on
`its Pathfmder World Wide Web
`site. The new-media operation
`is writing an all-Java stock-quote
`application as a test bed for wid-
`er use of Java at the server.
`Woods said.
`Burlington. Mass.-based Ob-
`ject Design has turned to the
`Web after failing to make much
`of a dent in traditional business
`applications, which still
`toward relational databases.
`Woods and other ObjectStore
`users said object databases pro-
`better performance and
`vide
`less painful development than
`
`lean

`
`Other new features of
`ObjectStore 5.0 include
`support for asynchronous
`data replication and
`automatic fail-over to a
`standby server.
`
`relational software for applica-
`tions that involve a complex mix
`of data.
`
`Paul Rogers, a scientific appli-
`cation developer at the Monte-
`rey Bay Aquarium Research In-
`stitute in Moss Landing. Calif.,
`said he looked at going relation-
`
`al for an upcoming intranet ap-
`that vkill store data

`about ocean creatures. But map-
`ping the data in relational tables
`would have been "daunting,"
`and the

`want to run hierarchical queries
`that relational databases "just
`struggle with," Rogers said. In-
`stead, he is relying on Java ob-
`jects and ObjectStore 5.0.

`
`AMDAHL CORP. this week will
`begin shipping software that
`lets users migrate data among
`vendors' disk storage systems in
`
`their data center.
`Called Transparent Data Mi-
`(TDM), the
`package
`gration
`gives users a flexible way to
`move data among their various
`mainframe disk systems. Most
`big data centers have storage
`systems from multiple vendors.
`"People continually tell me
`they want more than one ven-
`dor's storage devices in their
`
`data centers, since they don't
`want to bet all future functions
`
`on one company," said John Mc-
`Arthur, an analyst at Interna-
`tional Data Corp. in Framirjg-
`ham, Mass.
`Indeed, users at recent con-
`ferences have said that having a
`mix of storage systems in a data
`center helps them broker better
`deals and keep competition
`
`alive.
`
`MORE OPTIONS
`Data migration lets users move
`subsets of their databases to dif-
`ferent machines.
`For example, a data center
`may want to keep its marketing
`data on one system and finan-
`cial information on a more se-
`cure system. Or it may move old
`data to slower disk arrays and
`keep the most current data on
`high-speed systems.
`Most storage vendors, includ-
`ing Amdahl. EMC Corp. and
`Hitachi Data Systems Corp.,
`offer data migration utilities tar-
`their own storage
`
`geted
`
`at
`
`devices.
`Another advantage TDM pro-
`vides over those tools is that the
`
`does
`migration
`software
`its
`work in the background and
`doesn't require taking a system
`
`off-line.
`
`TDM pricing wasn't available.
`OfBdals at Amdahl in Sunny-
`vale. Calif, also confirmed they
`will try to sign OEM deals with
`other storage vendors to license
`the TDM technology.

`
`gets big bacl(er
`
`By Bob WaOace
`
`3COM CORP. last week became
`the first big networking vendor
`near-term
`Gigabit
`to
`offer
`Ethernet products. But network
`managers said the emerging IG
`bit/sec. networking scheme still
`has many limitations.
`Gigabit Ethernet technology,
`due for release in the third quar-
`ter this year, was designed to let
`companies add capacity to back-
`bone networks and provide fast-
`er access to server farms.
`3Com's entry (see chart) is
`important because the fledgling
`market was full of small start-
`ups, most of which won't ship
`products for several months.
`Although Gigabit Ethernet is
`far from robust, users said they
`
`can afford to wait for products to
`mature because their networks
`aren't heavily loaded.
`"We're anxious for Gigabit
`Ethernet products to hit the
`street so we can evaluate them.
`But our backbone network is
`only about 15% loaded, so we
`don't plan to replace it with
`Ethernet
`
`until
`
`early
`
`Gigabit
`
`1999," said Pete Bissonnette, a
`communications design analyst
`at Lockheed Martin Corp. in
`Pittsfield. Mass.
`
`WHAT NEEDS TO BE DONE
`Users and analysts said the fol-
`lowing issues need to be ad-
`dressed for Gigabit Ethernet to
`
`succeed:

`hasn't been settled. A standard
`approach is needed, especially
`between devices made by differ-
`ent vendors.
`Flow control needs to be fmal-
`ized. Without it, there isn't a
`foolproof scheme to assure data
`won't overflow device buffers
`and become lost. The same
`problem caused nightmares for
`users of early Asynchronous
`Transfer Mode (ATM) switches.

`copper support is expected later
`
`this year, at the earliest.
`
`"I plan to begin testing Giga-
`
`bit Ethernet products soon, but
`lack of support for copper is a
`big problem." said Ron Simms,
`a network engineer at |ohns
`Hopkins University in
`Balti-
`more. "We have fiber at our
`server farms, but we have cop-
`per in most other places."
`Gigabit Ethernet upUnks —
`products that tie LAN switches
`to Gigabit Ethernet backbones
`— are few and far between.
`
`Without them, users face the ex-
`pense of replacing switches.
`"Vendors were very late to

`Proprietary links help in mixed environments

`
`GROUPWARE DETENTE
`
`SOME USERS are rejecting In-
`ternet protocols and turning to a
`new crop of third-party tools to
`form tighter links between mes-
`saging and groupware servers
`from different vendors.
`Those tools could help com-
`panies ease migrations, manage
`mixed environments and share
`information with partners.
`Companies have been shar-
`ing electronic mail and directory
`information for some time via
`gateways and, more recently, In-
`ternet protocols such as Simple
`Mail Transport Protocol (SMTP)
`and Lightweight Directory Ac-
`cess Protocol (LDAP).
`But the new offerings go be-
`yond linking E-mail and directo-
`ries to handle the exchange of
`databases and the contents of
`public folders, as well as the
`conversion of groupware appli-
`cations from one platform to
`another
