Case Study 4
A company is experiencing a noticeable decrease in performance when accessing data purpose file shares. In addition, a file pool policy moves data that has not been modified 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 output from the netstat command:
- 32366653 data packets (35556615947 bytes)
- 8010 data packets (9525723 bytes) re-transmitted
Based on the output, what information should be provided to the administrator?
