23 Analyzing Dell PS Series Storage with SAN Headquarters | TR1050
3.1.1 Example 1: Before
Performance concerns are easily identified from the Combined Graphs dashboard where overall performance, capacity
and trends are included in the display. For instance, if free capacity trends downward, then the focus on the volumes or
snapshots consuming the most space. If latency were high in relation to the application tolerance, understanding which
pools the members or volumes are taking the most resources from would be important.
Below is an example Combined Graphs panel showing latency exceeding 25 ms. Also important to understand is the
actual client experience in order to help associate application delays with the latency in SAN HQ. For instance, if a client
is complaining about responsiveness around noon, then that time period should be the focus of the analysis.
