The access status chart graphs the access status data (IOPS value) that occurs in the Tier pool or FTV. By referring to the access status chart and by confirming the trend in the IOPS value, you can determine that the use of Automated Storage Tiering can achieve a performance increase and disk usage optimization.
Information
Even if the settings of an access status chart are changed, the access status data collected before changing the settings is not deleted. If the access status data collected before changing the settings exists in the generations of the access status data stored in the ETERNUS SF system, when displaying the pre-settings change access status data after having changed the settings, an access status chart may be displayed that does not match the changed settings.
