Exam E20-555: Isilon Solutions and Design Specialist Exam for Technology Architects (update January 28th, 2014)

you need to add in order to meet the required changes and not exceed 70% raw capacity?

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
65% utilized for their video surveillance operations.
They wish to achieve the following:
Upgrade from 1280 x 720 resolution, with a 15 days retention policy, to 2048 x 1536 resolution
with a 30 days retention policy.
What is the minimum number of nodes of the same type will you need to add in order to meet the
required changes and not exceed 70% raw capacity?

How many DataNodes does the Isilon Cluster have?

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 five node Isilon cluster. They have enabled the Hadoop cluster to access the files directly. The
nodes are X400’s with two SSD drives in each node and 96GB of RAM.

Which protocols would be the best fit when using Isilon for this customer’s Hadoop workflow?

A telecommunications company has a substantial amount of data. This data is being created by
network elements within their environment.
The company wants to change the way the network elements Call Detail Records (CDR) are
stored and analyzed. The existing infrastructure consolidates all of the CDRs into a table structure,
and then ingests them into a large database. Once ingested, a query engine accesses the
database and performs analysis on these files. The system is functional; however, since the
amount of CDRs generated will increase exponentially over the next year, the company is open to
alternatives for storing and analyzing these records.
In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the
amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs.
After you have conducted an assessment of the workflow, you have recommended an Isilon
Cluster to work within the Hadoop environment.

Considering the customer’s requirements, which is the best node type for the Isilon cluster?

What would you recommend be done to consolidate the three clusters into one?

Your customer manages a print media environment, consisting of three Isilon clusters, which are
out of support. The customer would like to have access to new software releases and feature sets.
You have been asked to perform a full discovery of the customer’s environment.
The customer’s current Isilon clusters are as follows:
“Cust” (12 x 12000X) serves as upload media storage for different tenants.
“Working” (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing
media from it.
“Archive” (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest,
three forest domains which are servicing three different environments. All servers are operating on
a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no
monitoring in place for performance measurement or optimization.
The requirements for this solution include:
Better ROI and TCO
Maintain same performance with possible improvements
Renew HW/SW and get inclusive support
Limit migrations

—–Reduce space, power, cooling consumption
Get new feature sets
If migration required, use Parallel copy (multiple nodes, multiple threads, multiple connections)
Segregate tenant shares from other tenants
Expand up to 1PB of total storage
What would you recommend be done to consolidate the three clusters into one?

Which licenses need to be defined for the solution to perform optimally?
