Question #6 (Topic: )
Refer to the exhibit.
[EMC-E20-555-6.2/EMC-E20-555-5_2.png]
Your customer has three different clusters. File systems on two of the clusters are at 90%
full, and the largest cluster is 10% full. Active data resides on the largest cluster. The
customer has five different node types totaling 2PB and 54 nodes. Nodes from left to right
are as shown:
1.X200
2.12000X
3.36000X
4.NL108
5.108NL
They have a Smartpool license and believe that tiering data would help free up needed
space.
After talking with the customer and explaining the use of SmartPools, how would you
recommend optimizing utilization across all of the nodes that the customer owns?

After talking with the customer and explaining the use of SmartPools, how would you
recommend optimizing utilization across all of the nodes that the customer owns?
A. Attach all nodes to a common Infiniband switch.
B. Go to GUI and put alike nodes in the same pools. Then name them.
C. Borrow nodes to reconfigure the cluster and migrate the data to new cluster.
D. Explain to the customer that this will result in data loss.
Answer: A
Question #7 (Topic: )
You are designing a new Isilon system to store mobile device video clips. The files average
800MB in size and the application team tells you to plan for up to 15,000 new files per day.
The product manager for this new service wants enough capacity for the first year and
reminds you that response time for storing and retrieving the files is important for customer
satisfaction.
The files will be accessed frequently for the first 48 hours after creation, and then very
infrequently after seven days. You plan to use N+2:1 protection, and will configure a
SmartPools policy to move inactive files to an archive tier within the cluster.
Which configuration best fits the project requirements?

D. It contains mostly random writes.
Answer: A
Question #10 (Topic: )
Your customer has an existing Isilon cluster with seven X200 nodes. The cluster is used to
store home directories and departmental shared folders. They are planning to deploy a new
application that generates small block, synchronous writes.
Which OneFS 7 capability can help reduce latency for the new workload?
