翻译指正:一篇测试稿

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?



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。
