Question 14

You have a customer complaining of long build times from their NetApp ONTAP-based datastores.
They provided you packet traces from the controller and client. Analysis of these traces shows an
average service response time of 1 ms. QoS output confirms the same. The client traces are reporting
an average of 15 ms in the same time period.
In this situation, what would be your next step?

  • A. The cluster is responding slowly and requires further investigation using performance archives.
  • B. The client that reports high latency should be investigated.
  • C. The cluster interconnects should be investigated.
  • D. A sync core should be triggered.

B

In this situation, given that the packet traces from the controller and client show different average service response times (1 ms on the controller and 15 ms on the client), the next step would be:

B. The client that reports high latency should be investigated.

Since the ONTAP QoS output and packet traces from the controller indicate a normal response time of 1 ms, but the client is experiencing much higher latency (15 ms), it suggests that the issue might be on the client side. Investigating the client that reports high latency would help identify any network, configuration, or resource issues that might be causing the delay.
