EMC Isilon Design Specialist Exam for Technology Architects : E20-554

A potential customer has 540TB Raw capacity of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. Their authentication sources are LDAP and Active Directory. Their users are primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing.
Which tool(s) would you use next to complete your sizing?

• A. Isilon Cluster Sizing Tool
• B. Wireshark, isi statistics, and iostat
• C. MiTrend WPA, Autosupport, and PerfCollect
• D. Isilon Insight IQ, OnCommand Insight, and nfsstat

What key considerations should be kept in mind when designing a 300TB solution?

• A. Defining class of service Time of day services ROI and TCO Data retention and backup
• B. Workflow management Defining class of service Time of day services RPO and RTO Data retention and backup
• C. Always include 2% SSD SmartPools Smartconnect Snapshots InsightIQ
• D. SmartPools Smartconnect Snapshots Space for snapshots

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?

• A. Create a six node X400 cluster today. As additional clients are added, add additional X400 nodes for them.
• B. Create a seven node X400 cluster today. You will not need to purchase additional nodes as more clients are added.
• C. Create a three node cluster today. As more clients are added, add three additional nodes each time for 1000 clients.
• D. Create a five node X400 cluster today. As more clients are added, add a Performance Accelerator node for every 1000 clients.

Refer to the exhibit.

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

• A. It uses large read requests.
• B. It is metadata intensive.
• C. It is mostly sequential reads.
• D. It contains mostly random writes.

-- Exhibit -
A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.
The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP. Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed.
The network expects 70 hours of new content per week, and 50 hours of edited content per week. They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for 30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.
In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements.

Based on the described use of the cluster, which node combination is the appropriate choice for the customer's requirements?

• A. 4 x X200 nodes with 4 x NL 400 nodes
• B. 4 x X400 nodes with 4 x NL 400 nodes
• C. 4 x S200 nodes with 5 x NL 400 nodes
• D. 4 x S200 nodes with 4 x NL 400 nodes
