DEE-1421 Expert - Isilon Solutions Exam Questions and Answers

A company has a medical application that generates a large number of media files. The file count is well over one billion and is stored on a Dell EMC Isilon 8-node NL410 cluster. Currently, each node is connected to the network using two 10GbE connections. The Linux-based application does not require high bandwidth; however, it is latency sensitive. Additionally, the Linux hosts are connected to the cluster over NFSv3. The application generates approximately 10,000 files every 10 minutes.

For the past four years, the cluster has been growing at a rate of one additional node per year. The company is running out of free ports on their redundant network switches. They want to know what can be done to ensure continuous availability. They do not want to invest in upgrading the network infrastructure. In addition, the company needs to reduce the number of consumed interface ports on the switches.

Which recommendation should be provided?

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?

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?

You are assisting a company in planning for a Dell EMC Isilon disaster recovery site. One of the company’s concerts is the time that is needed for the initial synchronization between the primary and disaster recovery sites.

What will help address this concern?

The :”nfs2” file system has been experiencing delays that have been impacting the entire Dell EMC Isilon cluster. Neither Snapshots nor SyncIQ is configured for these directories. Use the “Launch Simulator” button to verify the SSD strategy. Note: It is necessary to ‘close’ (x) the simulator window to answer the question.

Based on your findings, which operation should be performed to address the delays?
