原文:
Use a new explorer in SQL Server Management Studio to access the central management for multi-server management and at-a-glance dashboard views. Dashboard viewpoints provide insights into utilization and policy violation to help identify consolidation opportunities or resources at risk. What’s more, data and log file utilization are rolled up for visibility across databases and volumes—helping identify potential issues for you to pinpoint and take action.


data and log file utilization are rolled up for visibility across databases and volumes这句话困扰我半个多小时了,可还是想不出合适的翻译.不知哪位高人能指点一二,多谢了!!!

I don't think there is something with 'accumulation'.

data warehousing termiology

Roll-up
Aggregating data by use of hierarchies within the data. Allows for "drilling" up and down (traveling up and down the hierarchies) within a dimension.
Example: In a dimension table that keeps geographical information, you may have a Country-State-County-City hierarchy that allows you to "roll up" data to do analysis at certain levels in the hierarchy.

联机分析处理(OLAP)的基本多维分析操作有钻取(roll up和drill down)、切片(slice)和切块(dice)、以及旋转(pivot)、drill across、drill through等。  钻取是改变维的层次,变换分析的粒度。它包括向上钻取(roll up)和向下钻取(drill down)。roll up是在某一维上将低层次的细节数据概括到高层次的汇总数据,或者减少维数;而drill down则相反,它从汇总数据深入到细节数据进行观察或增加新维。
