可用性是以正常运行时间除以总时间的百分比来测量的。
Availability is measured in percent uptime divided by the total time.
最后，该电子表格还以总的集群大小的百分比来计算冗余容量——亦即包括额外部署的以支持可用性的服务器。
Finally, the spreadsheet also calculates the redundant capacity as a percentage of the total cluster size — i.e. including the additional servers deployed to support availability.
最后，您需要决定为支持可用性为每个组提供的总的冗余容量。
Finally, you need to decide on the amount of redundant capacity to provide each group to support availability.
总的方向包括性能、可用性、可伸缩性、可管理性、开发生产率、集成信息以及商业智能。
The general direction covers performance, availability, scalability, manageability, development productivity, integrated information, and business intelligence.
