A company wants to reduce the footprint in their data center. They recently completed a proof of
concept with Hadoop using Direct Attached Storage (DAS) for their Big Data initiative. You have

determined that incorporating an Isilon cluster into their Hadoop environment would help in
reducing this footprint. Which Hadoop components can be consolidated onto the Isilon cluster to
reduce the footprint?

Your customer is moving from a Restaurant/Bar business model to a Restaurant/Casino business
model. You are helping architect the upgrade of a current 4-node X200 48 TB Isilon cluster, with
50% utilized for their video surveillance operations.
They want to upgrade from 15 FPS (NTSC) in H.264 codec, with a 15 days retention policy to 30
FPS (NTSC) in H.264 codec, with a 30 days retention policy.
How many nodes of the same type will you need to add in order to meet the required changes and
not exceed 70% raw capacity?

capacity?

You are working with a healthcare company that is interested in replacing all the backend storage
for their PACS system. In general, how should the solution be presented to the customer?

You meet with the IT Director of a large single site campus. The IT department has recently taken
over Physical Security from the facilities department and plans a complete overhaul of the
surveillance solution. They are looking to you as a storage architecture expert to provide the
correct amount of storage needed. The IT Director asks you what items they need to provide in
order to size this solution. What data do you require from the customer?

A four-node Isilon cluster is being used in a Hadoop workflow with a parity protection of N+2:1.
The HDFS protocol has been enabled and is being used to access data.
According to EMC best practices, how many additional many additional copies of data are written
into the Isilon cluster using HDFS?

Your customer has a new business unit. They are gathering web log files to be analyzed. They are
using Hadoop to do the analysis of the logs. The IT department is centrally storing the log files on
a 5-node Isilon cluster. They have enabled the Hadoop cluster to access the files directly on the
Isilon storage. The nodes are X400’s with two SSD drives in each node and 96GB of RAM. How
many DataNodes does the Isilon cluster have?

A media and entertainment company has asked for help in creating a new Video On Demand
(VOD) storage system. The storage would be delivered to 5000 subscribers simultaneously. They
would like to store 5000 hours of full length, High Definition (HD) movies.
What would be the best price-to-performance node(s) for this solution?

Your customer has observed degradation in response time while browsing for media files within
the Production Media folder on the Isilon cluster. That directory now contains over five million files.
It was confirmed that there are no network or edit station related causes.
What changes to the Isilon cluster will best accelerate the browsing performance?

Your customer uses an existing Isilon cluster consisting of five NL-Series nodes to source
broadcast media files for playback and streaming. The customer reports that the playback pauses
and stutters regularly. It has been confirmed that there are no network or playback system issues.
Which is the appropriate choice to resolve the playback issues?
