NEC Storage PerformanceNavigator


Entire performance status can be grasped at a glance

Major performance indexes such as I/O density, transfer rate, response time, cache hit ratio of NEC Storage disk array systems can be graphed or displayed. Displayed items are preset and no prior setting is necessary. The items defined can be flexibly customized to efficiently grasp entire situation depending on purposes.

Multifaceted and efficient analysis of vast performance data

Performance status of related resources of a storage device can be analyzed in a lump. As detail analyzing functions, comparison of past performance data (at normal operation, on a specific day in a month, on a specific day of a week) and statistics data (average, median value), extraction by condition, automatic generation of summarized data by hour, day, or month are implemented. With these functions, multifaceted analyses of vast performance data created by various logged items and accumulation of past data depending on purpose of a user without much effort is enabled and detection of bottleneck and trend analysis can be made more efficiently.

Simplified integration of analysis environment

As data is analyzed off-line without constantly connected to other machines such as management servers, integration of analysis environment become simple and flexible. Performance data can be downloaded by simple operation at any time and various collected and analyzed data can be managed in a comprehensible integrated fashion by a tree view.
