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 average bandwidth
-98.8 ms average jitter
Based on the output, what information should be provided to the administrator?
