A customer is planning an Isilon deployment for use with their Hadoop environment. What is one
advantage of using Isilon as the HDFS layer?

A customer has an Isilon cluster that they want to simplify a Hadoop workflow. The workflow
analyzes large amounts of log data written to storage using FTP and results are viewed by
Microsoft Windows clients?
How can this be achieved?

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?

Which storage capacity would be the best suited to meet the required changes and utilize 65-75%
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.
How 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 nodes for this solution?
