DEE-1421 Exam Dumps : Expert - Isilon Solutions Exam

A Dell EMC Isilon cluster is configured with multiple 10Gb connections. Clients connect to the cluster using high speed links through a routed network. The cluster is configured with SmartConnect zones and servers NFSv3 clients. Network traffic and speeds appear steady. However, the administrator wants to ensure the cluster network performance is optimal.

What can help optimize network performance in this environment?

An IT team is implementing a disaster recovery solution. A Dell EMC Isilon cluster will replicate production data from the existing primary cluster to a planned secondary cluster. The primary cluster is licensed for SmartLock Enterprise whereas the secondary cluster is not.

A SmartLock enterprise type directory on the primary cluster is planned for replication. SyncIQ is used to replicate the data. What is a key consideration when replacing the WORM domain?

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 average bandwidth

-98.8 ms average jitter

Based on the output, what information should be provided to the administrator?
