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 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 the following traceroute output:

6 hops between clients and the cluster Average latency is 84 ms Based on the output, what information should be provided the administrator?
