计算机英语之分布式管理环境(1)

  Distributed Management Environment

  With the emergence of distributed multi- vendor computing environments, the creation of a standards framework to facilitate their effective management became a top priority. As a result, leading vendors, working through the Open Software Foundation(OSF) have developed a set of open, vendor-neutral standards known as Distributed management Environment (DME).

  DME was conceived to get the most out of to-day's advanced distributed computing technologies.open standards,interoperability- and object-oriented technologies.Its standardized framework represents an industry consensus on application pro-gram interfaces (APIs) and protocols for open man-agreement. DME is a 'living' standard, evolving as technologies evolve enhancing the latest industry developments.

  1.Why DME Works

  DME builds on existing standards.It is not an alternative to other standards. Rather, it represents acomplementarv approach that encompasses existing SNMP and CMIP standards and endorses interfaces devised by the Network Management Forum X/Open and others.

  DME is the product of a multi-vendor, consent-sus-based process.As a result, DME maps to your computing environment and manages growth inmulit-vendor systems and networks.And because DME is the product of industry consensus it accelerateates the process of reaching consensus within your organization.

  DME is based on a comprehensive set of requirements developed through an open industry process to meet specific objectives and address real needs.

  DME is vendor neutral. It enhances competition in the management market.This will result in lower costs and better solutions for users.

  2.The Benefits

  Dame's wide-ranging benefits include:

  (1)A scaleable, distributed architecture that can accommodate growth in multi-vendor networks and distributed systems.

  (2)Better management, interoperability and integration through the implementation of common management services and standardized protocol adobe definitions.

  (3)Reductions in time and costs for system administration and training.

  (4)Tightly integrated solutions utilizing objectoriented design, for easier and more flexible integration of scaleable,distributed,multi-vendor architectures

  (5)Greater longevity of systems resulting from standards-based, backwards compatibility.

  3.What you can do today

  No matter where you are in the development of your network, we suggest evaluating DME as you build your enterprise management strategy. Portions of the DME will be available during 1993 from number of vendors.Complete implementations ode win begin appearing in 1994.

  Distributed systems demand the same level of management and availability that IS has historically provided in a mainframe environment. Yet the technicely approach to distributed systems management is fundamentally different from that applied to central-sized system.

  Hardware and software resources to be managed tend to be more numerous, widely-dispersed and provided by a wide variety of vendors.Put sumply, old approaches to systems management cannot be incrementally extended to manage these new distributed systems.A new approach is required.

  When compared to centralized mainframe environment, tracking and intervention tools for distributed systems management still appear somewhat primitive even as the number and variety of systems IS professionals are expected to provided backup and recovery services,fault isolation and repair capability-ties, and updating procedures that provide levels of service similar to those users have come to expect from centralized systems.These demands all threaten to increase administrative and support expenses.

  If these systems are poorly managed. there's real chance such expenses may actually erase the cost reductions achieved through downsizing .

  Effective distributed systems management ad-dresses these issues.It provides the considerable business benefits of distributed computing with context that allow for effective management of IT resources and cost.

  A strong distributed systems management policy will result in the same level of production-quality service provided by traditional mainframe opera-dons.Distributed systems management allows for growth in the number of managed systems while reducing support requirements and lowering costs.It increases system availability, security and integrity. It provides remote systems management, which intern provides an enterprise-wide perspective, the more effective use of limited support resources,and the basis for higher levels of automated management.
