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?
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?

Case Study 5 – Refer to the Exhibit.
Backing up data from a Dell EMC Isilon cluster exceeds the company’s backup window. Because the company has a large amount of data with a continuous high growth rate, they want to change their backup strategy. The Gen 6 Isilon cluster consists of 24 nodes. Their current backup strategy is an NDMP three-way backup performing weekly full backups to tape and incremental backups each night. The strategy uses Dell EMC NetWorker. The DMA uses Include paths to specify what data to backup. All data on the cluster must remain accessible.
The company’s IT team is now looking for a method to increase the performance of their backups. After some investigations, you notice that the backup job quiesces the file system. This is creating lock contention issues on open files and not allowing users full access to data when the backup job runs.
What advice should be provided to the team to eliminate lock contention and allow full access to users?
