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?

A Dell EMC Isilon administrator wants to know which workloads benefit from using L3 Cache. Which type of workloads will address the administrator's inquiry?

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 details of the hostcahce.list output. The output indicates that the top clients on the list have an average of 242 ms round trip time. Based on the output, what information should be provided to the administrator?

A Dell EMC Isilon cluster replicates critical production data and long-term archive data from the primary data center to a target cluster. The source cluster runs OneFS8.1 and the target cluster runs OneFS7.2OneFS will not be upgraded on the target cluster

When the archived data on the source cluster is replicated to the target cluster, the capacity consumption on the source cluster far exceeds what is expected. What is the reason for the increase in capacity consumption on the cluster?

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 lsilon 8-node N14I0 Cluster Currently, each node ft connected to me network using two 10GbE concoctions. 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 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 ol consumed interface ports on the switches.

Which recommendation should be provided?
