Determining whether a workload has a performance issue

A storage administrator receives a call from a customer whose Microsoft Exchange Server is responding very slowly. The administrator analyzes the volume workload that is storing the Exchange data to determine whether the issue is on the cluster.

Before you begin

About this task

If you are viewing the Incident Details page, you can click the name link for a volume to go directly to the Volume Details page.

Steps

  1. In the Search bar, type the name of the volume.
    The name of the volume is displayed in the search results.
    Note: The Search bar requires at least three characters before the results can display the names of objects that contain those characters.
  2. Click the name link of the volume.
    The volume is displayed on the Volume Details page.
  3. On the Historic data chart, click 5d to display the last 5 days of historical data.
  4. Review the Response Time chart to answer the following questions:
    • Are there new incidents?
    • Are there historic incidents, indicating that the volume has had issues in the past?
    • Are there spikes in the response time, even if the spikes are within the expected range?
    • Have there been configuration changes on the cluster that might have impacted performance?
    If the response time for the volume does not display incidents, spikes in activity, or recent configuration changes that may have impacted the response time, the storage administrator can rule out the performance issue being caused by the cluster.
