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?
Answer : A
A company has 7 PB of PACS archive data on their Dell FMC Isilon cluster. The PACS application currently creates and stores large containers of small files. Based on local healthcare regulation changes, the company can no longer use large containers of small files. As a result, the company wants to know if Isilon can support the new regulatory PACS requirement while maximizing the storage capacity for small tiles

Testing shows that alerts were working for several days but have suddenly slopped. Which action is required to resolve this issue?
Answer : A
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?
Answer : C
