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 following iperfoutput
890 Mb/s avenge bandwidth
96 8 ms average jitter
Based on the output, what information should be provided to the administrator?

1. A. Amount of jitter a an indication of network congestion
2. B. Numbers remain within the recommended range
3. C. Amount of jitter is in an acceptable range
4. D. Lower than average bandwidth needs to be investigated

Correct Answer: D

A company has a Dell EMC Isilon cluster that will be used for a large amount of client requests. SmartConnect has been configured to help load balance the clients across the cluster. How does SmartConnect help the load balancing?

1. A. Dynamically updating changes to DNS
2. B. Caching lookup requests
3. C. Forwarding DNS requests
4. D. Directing the connections to different nodes

Correct Answer: D

A company has a Dell EMC Isilon Gen 5 cluster with SSDs in each node. The administrator notices that L3 Cache is enabled on the cluster. However, the administrator does not notice any performance increase for the read I/Os. After further investigations, the administrator discovers that all read I/Os are more than 128K chunks.
Which recommendation should be provided to improve the read performance?

1. A. Enable Global Name Space acceleration in addition to L3 Cache
2. B. Change theSSD strategy to "data on SSD"
3. C. Disable L3 Cacheand change the SSD strategy to 'metadata-road acceleration''
4. D. Add one more SSD of equal capacity to each node

Correct Answer: C

A Dell EMC Isilon administrator wants to know which workloads benefit from using L3 Cache. Which type of workloads will address theadministrator’sinquiry?

2. B. Sequential and streaming
3. C. Streaming only
4. D. Random

Correct Answer: B
