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 iperf output
890 Mb/s avenge bandwidth
96 8 ms average jitter
Based on the output, what information should be provided to the administrator?
A Dell EMC Isilon administrator has reported that in Access zone ''ProdZone'' on the OneFS file system ''nfs1'', Microsoft Windows ''DEES\user1'' has root level permission on nfs1. Use the ''Launch Situation'' button to examine the environment and validate the reason for this condition. Note: It is necessary to ''close'' (x) the simulation windows to answer the question.
Based on your findings, what is the reason for the condition?
A company wants to purchase four new Dell EMC Isilon H500 nodes to add their current Gen 5 cluster. Which internal requirements are needed?
A company has an environment with multiple AD in a one-way trust relationship. The AD provider on the cluster is configuring with SFU. The trusted domain is failing to supply UIDs and GIDs to the EMC Isilon cluster. As a result, user from the trusted domain is receiving an access denied error message.
What is a possible reason for the denial?

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?
