Isilon Solutions and Design Specialist Exam for Technology Architects v6.2

You have scheduled a meeting with a prospective customer in the Life Sciences vertical market. Which Isilon features should be presented to them?

A potential customer requires 800 TB 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 considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.
Which Isilon capabilities would show a better ROI for the customer?

Your customer purchased an Isilon cluster with eight X400 nodes for Home Directories.
Your follow-up discussions have uncovered an opportunity to expand the cluster to support the Legal Department. As you prepare to complete the Workflow Profile Document, you meet with the customer to discuss data protection.
Which key areas should you address?

A customer has a data retention period of three years. They want a solution in which files cannot be deleted, changed, or modified.
Which Isilon SmartLock version should they implement?

Which type of data is stored in Endurant Cache of an Isilon node?

A customer wants to replace a legacy storage environment used for high definition video editing. Each workstation connecting to the shared storage needs to sustain 650 MB/s of single stream bandwidth.
Which node type is recommended?

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?

A customer environment is used for analytics on very large datasets. They are interested in using Isilon storage and Hadoop but are concerned about the costs.
How does Isilon change the scalability of a Hadoop environment?

When a client requests a file to read from an Isilon cluster, in which order does the read operation access the hardware in a node?

You have gathered information from your customer about their current NAS environment.
They indicated they are having performance and time-out issues with their clients accessing the storage. Currently over 5000 clients are simultaneously accessing the NAS; however, this will double in the next year.
Based on this information, what recommendations for a new Isilon cluster would you give to the customer based on this information?

What is the minimum number of nodes in an Isilon cluster for N+2 protection?

A customer wants to add Unix users to their cluster, and requires that NFS access be fault- tolerant.
What would you recommend?

An Isilon storage administrator is concerned about capacity after ingesting 200 TB of file data. They recently added more nodes to the cluster and now want to auto-balance it as soon as possible.
The cluster utilization percentages for an average 24-hour period are:
-> 45% during 00:00 - 08:59
-> 60% during 09:00 - 17:00
-> 85% during 17:01 - 23:59
The administrator wants to keep cluster utilization at a minimum. Which Impact Policy settings should be used to quickly complete the job without impacting the production workload?

You are called into an opportunity, you would like to get more information on the data skew of the filer. The customer has a supported filer.
