最近我翻译过一片测试稿，里面的有些内容迄今尚不满意，但功力有限，难以再进行完善。现在贴出来，如果有感兴趣的朋友，可以一起评论、修改。
For the vast majority of users, the viable SAP R/3 platform choices through 2001 will be limited to Windows NT (on Intel) and Unix (Hewlett-Packard, Sun Microsystems, IBM and Seimens Nixdorf), while OS/390 Open Edition and OS/400 will be available for current users whose platform loyalty outweighs other considerations (0.8 probability).
Key Issue: How should users best select server platforms and vendors for RDBMS and application server roles during the next five years?
[graphic chart, omitted]
The chart above summarizes our major findings regarding three critical differentiators for SAP R/3 platform selection: Market share (a current snapshot -- expect improvements for Windows NT and Sun), Performance and scaling (determined by current high water marks) and High availability (failover and clustering functionality).
By the time a platform decision must be made, most users have already contracted with an external service provider or system integrator for the R/3 implementation assistance required, so system vendors’ R/3 professional service expertise may be an irrelevant differentiator. The timeliness and quality of system vendors’ hardware and software maintenance can be a differentiator, but only if verified by \"local\" references. System vendors that propose a heterogeneous solution (e.g., Windows NT application servers running against a Unix RDBMS server) introduce another level of management and problem resolution complexity and management cost into the picture.
Action Item: We recommend that users always check vendors local references for hardware maintenance, due to extreme quality variations we have seen on a geographic basis.
对绝大部分用户来说，2001年全年可行的 SAP R/3 P 平台之选将限于Windows NT 系统（基于Intel）和Unix系统（HP系统、Sun微系统、IBM系统和Simens Nixdorf系统）。但OS/390（开放版）操作系统和OS/400操作系统也适用于当前用户，它们的平台较其他可供考虑的平台具有更高的忠诚度（概率值为0.8）
关键问题：在接下来的五年里，用户应如何最优地选择服务器平台、RDBMS销售商以及伺服器角色？
[省略图表]
以上图表总结了关于SAP R/3平台选择的三个关键区分因素：市场份额（根据目前状况预期，windows NT 和 sun 的市场份额会不断上升）、性能和扩展性（由目前的高水平线决定）、以及高可用性（容错和聚集功能）。
当决定选用一个平台之前，大部分用户已与外部服务销售商或系统集成商达成协定，用以为R/3的执行提供必要的协助，所以，系统供应商所能够提供的R/3专业服务技能可能只是一个无关紧要的区分因素。系统销售商的软硬件维护的时效性以及质量也可以是一个区分因素，但此区分因素仅当系统销售商经过开发方认证后方能成立。系统销售商也可建议不同种类的解决方案(例如：windows NT 应用服务器与Unix RDBMS服务器不能兼容运行)，此时，系统销售商在我们所讨论的问题中引入了另一等级的管理、问题决策复杂度以及管理成本。
注意事项：建议用户经常检查销售商硬件维护的资质认证，因为已经注意到，不同地区的销售商，其服务质量存在着极大差异。 |
