A customer is looking for a NAS solution to support their read-intensive application. This solution must meet the following requirements:
– 1000 users
– Aggregate bandwidth of 5 GB/s
– 500 TB of user data
– Typical latency of 5 ms.
The files are distributed evenly across 10 directories. Which cluster configuration would best meet these requirements?

A.    Seven X400 (108 TB) nodes with no SSD.
B.    Eight NL400 (96 TB) nodes with 1.6 TB SSD.
C.    Eight X400 (96 TB) nodes with 1.6 TB SSD.
D.    Twenty-five X200 (30 TB) nodes with 800 GB SSD.

Answer: C

A NetApp customer is considering Isilon. They use their filers for UNIX home directories, and would like to see a suggested configuration that would meet their needs. What would you do to help size this cluster?

A.    Use tcpdump and upload the output file to MiTrends to generate a protocol analysis.
B.    Ask for an autosupport file and upload it to MiTrends to generate a workflow profile.
C.    Ask them to install InsightIQ and collect data from the filer, then import to SQL for analysis.
D.    Ask for the output from nfsstat and upload it to MiTrends to generate a workflow profile.

Answer: B

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 50 TB 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?

A.    3 x NL400 nodes with 2 TB Drives.
B.    3 x X400 nodes with 1 TB Drives.
C.    5 x X200 nodes with 1 TB Drives.
D.    6 x X200 nodes with 1 TB Drives.

Answer: D

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.    Prefetcher
B.    Endurant Cache
C.    Solid State Drives
D.    L2 Cache

Answer: B

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?

A.    What does your infrastructure look like?
What applications access this storage?
What protocols and version number?
B.    How much capacity are you looking for?
What applications access this storage?
What risks are there in your current infrastructure?
C.    What filesystems, SMB, NFS, or other are you using?
What does your infrastructure look like?
How do you manage your File Systems?
D.    What is your network infrastructure like?
How many Storage Fabrics do you have?
What is your Disaster Plan for the Newspaper?

Answer: A

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?

A.    Use Backup Accelerator nodes for 3-way NDMP.
B.    Use Backup Accelerator nodes for 2-way NDMP.
C.    Use SmartConnect Advanced and 10Gb/s network interfaces with LACP.
D.    Use an Avamar NDMP accelerator and dedicated 10Gb/s network interfaces.

Answer: B

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 600 TiB 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? How many clients will access the File System?

A.    Will their VDI clients access the Isilon Cluster?
What is the DR plan for the ERP System?
What Enterprise Resource Planning platform are they using in manufacturing?
B.    What is their Recovery Point Objective?
What is their Archival Strategy?
What non-sizing-specific factors in the customer’s environment could impede integration of the Isilon solution?
C.    What applications are they using?
What are your priorities among performance, scalability, or availability?
How many data centers do they have?
D.    Will their Network Infrastructure support implementing Isilon?
What Enterprise Resource Planning platform are they using in manufacturing?
