An Isilon customer has two 5-node clusters, one for production and one for disaster recovery (DR).
The customer’s workflow is a SmartLock workflow and is replicated to the DR cluster through
SyncIQ on an individual schedule. The customer needs to shutdown their production cluster for
scheduled maintenance.
Assume both clusters have identical shares, exports, user authentication, and that the client
applications have been stopped and the DNS re-pointed. What is the correct method to start
operations on the DR cluster?

You have been invited to meet with the Social Media and Marketing Department and gather
requirements for a potential File System Project. They primarily use CIFS and are considering
deploying a Hadoop cluster to analyze customer demographic data. The Senior Systems Engineer
thinks they will need 2PB of usable capacity.
What would you do to gain an understanding of the customer’s environment to qualify and develop
the opportunity?

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.
Which questions about architectural integration will impact the solution design?

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 10 questions led to this information?

You are sizing an Isilon Cluster for a new customer. Analyzing their workflow, you determine that
they have a small block random read workload.
What is the most important factor to consider when sizing this solution?

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?

Refer to the exhibit.

You are analyzing a customer’s existing Isilon environment using InsightIQ in order to expand the
cluster. When examining the protocol data, you see the output as shown.
What does the data tell you about the workload?

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?

An existing customer has two NAS systems providing NFS storage in their main datacenter – one
is an Isilon cluster and the second is an array from another vendor. Both systems are four years
old, and the customer would like to consolidate the storage into a single solution. According to the
customer, both systems support identical workloads with similar performance and utilization, and
they want the new solution to support 50% performance growth.
Which method can model the workload requirements, and what multiplier will capture the
requirements for the new solution?

A potential customer is considering replacing a four year old, Linux-based NFS server with 40TB
of usable capacity. The existing system supports home directories, an internal website, and a
content repository for the customer’s content management system. The customer is concerned
about performance of any new solution because they expect to double workload in the content
management system.
What tools can be used to collect performance data needed to size the new solution?
