Exam 5: XtremIO Solutions and Design Specialist Exam for Technology Architects

An Isilon customer has an environment supporting a wide range of different workloads. They want to assign clients to performance tiers based on the resources needed. What can the customer use to meet this requirement?

An XtremIO administrator is having a problem with performance and is troubleshooting the issue. What is an accurate statement about I/O transfers?

-- Exhibit -- We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data. They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster. The customer will add two more Illumina Hi-Seq Sequencers in the next 6 months. Once these are added, what is the total amount of data from all the sequencers they can expect to add per month?

-- 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. -- Exhibit - The customer wants to be able to put completed content into a non-editable folder. However, they want to give access to an administrator to delete content if required. What do you recommend to the customer?

A cost-conscious customer is exploring Isilon for their PACS archive. The workflow consists of one hundred cases a day, each including fifty 60MB image files. However, each image will have five-hundred 64kB metadata files associated with it. They currently have six years worth of archived data. They will need to migrate to the new solution and they need to plan for an additional three years of archive capacity. Which solution would you recommend to fit their capacity needs?

A customer wants an N+3 protection level on their cluster. What is the minimum number of nodes they need to achieve that level of protection?

An Isilon customer expressed an interest in more effectively managing their storage. Specifically, they would like to plan for future growth. Which tool would allow the customer to forecast capacity requirements?

A customer has a 5 node Isilon cluster. The raw capacity of the cluster is 85% used. On average, the cluster has 4,000 users connected during office hours. The average CPU usage is 65%. The customer needs to delete some data to free up capacity. What should the customer do to minimize the effect of the deletion job?

A customer has a cluster running with a single access zone and serves multiple internal departments. The clients access the cluster over both SMB and NFS protocols. A department user has been assigned the task of auditing SMB activity and enforcing appropriate quotas for certain users. How should the cluster administrator grant this access?

In an Isilon environment, how is InsightIQ installed?

What is the recommended namespace path for the access zone on a new Isilon cluster with SyncIQ license?

In an Isilon cluster, what is the largest number of nodes that a single file can be striped across?

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 customer is using file pool policies to archive infrequently accessed files to Amazon S3 via CloudPools. How could the customer easily find out how many stub files are stored on the cluster?

A telecommunications company has a substantial amount of data. This data is being created by network elements within their environment. The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records. In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs. After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment. What would be the best recommendation to the customer for the workflow of Hadoop with Isilon?

Based on XtremIO Data Protection, how many dedicated hot spare disks per X-Brick are required?

Refer to the exhibit. A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 60 TB of RAW capacity. The following are the notes from meetings with the department heads. Which is the minimum cluster configuration that meets the customer's requirements?

A storage administrator is adding both an XtremIO and third-party storage arrays to their existing infrastructure. The administrator is using ViPR SRM to monitor the environment. Which requirement is needed to implement this solution?

A customer has installed an Isilon Gen 6 cluster as a Proof of Concept. Before making a purchase decision, they would like to compare the performance of the Isilon to competitive offerings. Which tool can be used to provide data analysis and benchmarking through existing workflows?

Your customer has observed a degradation in response time while browsing for media files within the Production Media folder of the Isilon cluster. That directory now contains over five million files. It was confirmed that there are no network or edit station related causes. What changes to the Isilon cluster will best accelerate the browsing performance?
