The performance monitoring function as an optional function collects performance information on the disk array at a
predetermined interval, from one to six times per minute and reflects the resulting data on the Numeric Table or Graph.
The performance display refresh rate is defined in advance by the Storage Manager Setting Utility before the iSM
server is activated and can be changed dynamically via the performance display refresh rate change function while the
iSM server is operating.
For details on the changing of the performance display refresh rate, refer to 1.5.1 “Real-Time Display of Load Status”
of the “PerformanceMonitor User’s Manual”.

To effectively utilize the disk array, it is important to regularly analyze the usage state and load balance of the disk
array and perform tuning including the optimum arrangement of files and expansion of devices. The iSM provides the
following performance analysis supporting tools aiming at support for performance analysis of the disk array:
(1) Archiver
The Archiver summarizes the statistic information of the disk array stored by the iSM on an hourly or daily basis.
Use of the Archiver reduces the statistic information volume thus saving the disk capacity necessary for
accumulating statistic information.
