You have had several meetings with an existing EMC VMAX customer. They have agreed that
they would like to review an initial Isilon Solution for unstructured data used by the Product
Development Team. All production is managed through a Global Enterprise Resource Planning
system based in Germany. They require 600TiB of usable capacity. The File System must be
accessible from Windows and Linux High-End Workstations. The files are generally not accessed
after 120 days, and they would like automated tiering.

Click on the calculator icon. A customer plans to replace an existing array that is supported by the
MiTrend Workload Profile Assessment (WPA) service. You receive performance data from the
customer and run a WPA report that shows the array has 50TB of usable capacity.
In discussions with the customer, you learn the content is comprised of four million 6MB files and
400 million 64KB files. The customer explains they have a small budget and very limited rack
space available in their datacenter. Performance is not a concern because the files are rarely
accessed.
Which configuration provides the needed usable capacity using N+2:1 protection, and requires the
least amount of rack space?

You are designing a new Isilon cluster that requires backup to tape for all files in the Legal and
Accounting shared folders. The customer has sized their IP network to support the application
workload, but no additional bandwidth is available.
What should be recommended for the backup solution?

Click on the calculator icon. Your customer is looking for a storage solution that will be able to
store seven million three MB files which are written and seldom accessed. Read and write
operations are both completed by a web based application, which requires 1.3 Gbps throughput.
The customer’s network has not been upgraded in many years, so the network interfaces are
1Gbps.
Which cluster configuration would best meet the customer’s requirements?

You are asked to size a cluster for a file sharing environment. nfsstat indicates that 75% of the
requests are namespace operations (e.g., GETADDR, SETADDR). There will be 8,000 active
Linux users, connecting over NFS.
Which cluster configuration would you recommend?

Your customer is a major metropolitan newspaper. Your previous discussion centered on their
storage requirements, and you asked them some of the Top Ten questions.
They responded: “Well, it’s not the prettiest or most high-tech solution…we use Secure FTP
(SFTP) to upload the stories and images and put them in a workflow that formats them for printing
in the newspaper.” “What really worries us is the fact that our Storage Array from your competitor
is going out of maintenance in 120 days, and they are dropping support for Secure FTP. This isn’t
even considered in our D/R Plan. Do you have a better solution with Isilon?”
Which Top Ten questions led to this information?

An administrator recently installed InsightIQ to gather cluster statistics, and wants to look at file
system usage (such as the number of files in a directory). However, currently no file system
statistics are displayed in InsightIQ after 24 hours. Use of the cluster is moderate, and occurs 24
hours per day.
What job for InsightIQ should the administrator modify to successfully report these statistics?

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?

A potential customer requires 800TB of usable capacity to store medical images for their network
of health clinics. The IT department has limited staff and currently manages four storage arrays
from other vendors. During a meeting with the Director of IT, you learn that the company is
planning to deploy a scale-out NAS solution from a competitor of EMC.
Which factors can demonstrate a lower TCO using Isilon?

A Media and Entertainment company is considering changing from 2K resolution to 4K resolution.
They will continue to use the DNxHD 220 codec.
Assuming everything else stays the same, how will this change affect storage?
