`
`Keeping Up with Network Technologies and Standards
`
`Updated spec provides standard
`for remotely managing computers
`
`By Paul Ruocchio
`[If you want to remotely manage
`networked
`computers while
`complying with industry stan-
`dards, check out products that
`support the soon-to-be-released
`updated version of the Desktop
`Managementinterface (DMI).
`Version 2,0 ofthe DMI spccifi-
`cation details.a standard way for
`sending management
`informa-
`tion from remote devices across
`
`agement applications. The MIF
`database defines the standard
`manageable attributes of PC
`products.
`The MI
`lets DMb-enabled
`applications access, manage and
`control
`desktop
`computers,
`components and peripherals,
`while the Cl allows components
`to be seen and managedbyappli-
`cations that call the DMI service
`layer. The (I gets
`real-time
`
`relevant management
`extract
`information, the DML now usesa
`procedural API composed ofsev-
`eral discrete functions. These
`functions can casily be described
`using the Open Software Foun-
`dation,
`Inc.'s (OSF)
`Interface
`Description Language (IDL).
`Theuse of IDL is important
`because it allows information to
`be categorized rather than pre-
`sented in black form. Moresig-
`
`
`
`Update impact
`Desktop operating systems
`that
`recognize products
`that
`comply with DMI Version 1.0 can
`accommodate the updates. The
`DMIs CI
`is defined such that
`new code will be required to
`accommodate
`Version
`2.0
`enhancements.
`However, the Cl changes will
`not
`immediately
`affect
`the
`installed base of DM -enablecd
`hardware, which can still be
`accessedat the Version 1,0 func-
`tonality level by DMI-enabled
`managementapplications,
`The DMI and MIFs were
`developed
`by
`a
`cooperative
`industry consortium with 122
`formal members and technical
`dialogues with more than 350
`companies,

`Release: 2.0 of the Desktop

`in the specification’s initial
`version Lo a procedural MI,
`which enables remote access.
`
`the network toa central site. The
`release also allows managers to
`define and filter events, such
`as alarms, sent oul by the man-
`aged PC products, servers and
`software.
`The Desktop Management
`
`Task Force (OMTF), an industry
`group, plans to release DMI Ver-
`sion 2.0 early next month, The
`release extends DMI Version 1.0,
`which established a standard
`
`| framework for man:
`ging tet-
`worked computers, The DMI is
`independent of protocol, plat-
`form and operating system.
`Architectural overview
`The DMI architecture in-
`cludes a service layer, a manage-
`ment information format (MIF)
`database, a management inter-
`face (MI)
`and a component
`interface(CT),
`The DMI servicelayer acts as
`an information broker between
`manageable products and man-
`
`dynamic instrumentation infor-
`mation from manageable prod-
`ucts and passes it to the Mi via the
`service layer. It shields compo-
`nent vendors
`from decisions
`about management
` applica-
`lions, protocols and operating
`systems, allowing them to focus
`on providing competitive man-
`agementlor their products,
`The DMTFtechnical commit-
`tee has fine-tuned the original
`
`DML with two enhancements: a
`procedural interface and a self
`describing event model.
`
`Procedural interface
`The DMI Version 1.0 uses a
`block structure interface with a
`single API.
`the ser-
`With this interface,
`through
`vice layer has to sift
` =
`large amounts ofindiscriminate
`data to access required inform:
`tion. What's more,
`it has been
`prone to errors.
`To make it easier for users to
`
`nificantly, it allows an interface
`to be used with the OSP's Distrib-
`uted Computing Environment's
`remote procedure call function.
`This makesit possible to use the
`interface for remote manage-
`ment.
`
`Event model
`
`The DMI Verstan 1.0 specii+
`cation incorporates a highly flex-
`ible event model, However, pwo
`things are missing: 4 Way tO cle-
`scribe events and a mechanism
`
`for filtering those events before
`forwarding them to a manager.
`Asaresult, management applica-
`tions receive a plethora of indis
`tnguishable events.
`In Release 2.0, the DMI gains
`the ability to define events within
`a component's MIF and toset
`event filters in the service layer,
`This means managers can estab-
`lish
`severity
`thresholds
`and
`determine the types of events for
`which they receive notification.

`do. Here is an example:
`Recently, Brett Stuart, supervisorof
`LAN operations for ALLTELCorp. in
`Little Rock, Ark., told us that making
`achangeto his Madge Networks, Ine.
`FDDI network interface cards (NIC)
`salved a ring operations problem. He
`says that about every sevendays, the
`FDO! ring would go into a high rate of
`ring-cperations/transitions between
`the primary and secondary ring.
`Originally, his Novell, Ine, Net-
`Ware d.X.and 4.4 servers used dom
`Corp.
`single-attach station FDDI
`cards with the latest drivers, but
`alter
`the
`problem started,
`be
`changed to Madge’s dual-attach sta-
`tion (DAS) cards with that compa-
`ny's latest drivers, which werein beta
`testatthetime.
`However, the Madge cards did not
`eyele correctly in DAS made, appear-
`ing to hang up and never reestablish
`communications.
`After consideringchanging again
`to Cisco Systems, Inc, DAS cards,
`Stuart saysusing the Madge cardsin
`SAS mode finallystabilized the FODI
`ring. The networkis running fine
`now except for occasional problems
`with NetWare Directory Services.
