[All DEE-1421 Questions]

Case Study 4

A company is experiencing a noticeable decrease in performance when accessing data on their Dell EMC Isilon cluster. The cluster hosts Microsoft Windows home directories and general purpose file shares. In addition, a file pool policy moves data that has not been modified in six months to an achieve tier. The administrator wants your assistance in understanding the reason for the slow data access. The number of users accessing the cluster has not changed. The administrator has shared the following baseline metrics. The outputs were captured from a performance- acceptable time frame.

Trace route shows:

-3 hops between clients and the cluster

-Average latency is 3 ms

Iperf shows:

-940 Mb/s average bandwidth

-005 ms average jitter

Netstat on the local network shows:

-05% average re-transmission rate

Hostcache list:

-20 ms average roundtrip time across all clients

The administrator shows you the details of the hostcahce.list output. The output indicates that the top clients on the list have an average of 242 ms round trip time. Based on the output, what information should be provided to the administrator?

I believe the acceptable range for average round trip time is less than 300 ms. We should inform the administrator about this.

That could be a good idea. It might help in identifying any specific issues causing the slow data access.

Should we also consider recalculating and re-populating round trip times using the isi_cbind clear command?

I think we should provide the administrator with the information that an increase in average round trip time indicates a network problem.

Exactly! I think option B is the way to go. We should recalculate and re-populate the round trip times using the isi_cbind clear command to get a more accurate picture of the network performance.

I'm not so sure about that. The question specifically mentions that the top clients have an average of 242 ms round trip time, which is quite high. That's the key information we should focus on.

I agree, since the top clients have an average of 242 ms round trip time, there may be a network issue.

But wait, the question says the average round trip time across all clients is 20 ms, which is within the acceptable range of less than 300 ms. So, option D might be the correct answer.

Hmm, I'm leaning towards option C. An increase in the average round trip time does indicate a network problem that could be causing the performance decrease.

This question seems a bit tricky. We need to carefully analyze the information provided and determine the root cause of the performance issue.
