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

A customer created eight SyncIQ policies on a 6-node Isilon cluster. The policies all start at midnight. The customer is experiencing issues where several jobs are paused while others continue to run. This is delaying the overall replication of data. What is the most likely reason for the pausing of some of the SyncIQ jobs?

A customer is able to see some performance metrics in the Isilon OneFS dashboard or by using CLI. Other performance metrics will require InsightIQ. What will require a licensed version of InsightIQ?

-- 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. Refer to the exhibit. Based on the described use of the cluster, what are the customer's capacity requirements?

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?

An administrator receives an error on an XtremIO array while performing snapshot refreshes to a production volume. What is a potential cause for this issue?

Given a 5-node Isilon cluster configured with an N+2 protection level, how many nodes can be offline with the data accessible and fully writeable?

Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer's environment. The customer's current Isilon clusters are as follows: "Cust" (12 x 12000X) serves as upload media storage for different tenants. "Working" (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it. "Archive" (16 x 72NL + Accelerator nodes) is used to store printed content for six months. The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization. The requirements for this solution include: Better ROI and TCO Maintain same performance with possible improvements Renew HW/SW and get inclusive support Limit migrations Reduce space, power, cooling consumption Get new feature sets If migration required, use Parallel copy (multiple nodes, multiple threads, multiple connections) Segregate tenant shares from other tenants Expand up to 1PB of total storage What would you recommend be done to consolidate the three clusters into one?

You will be meeting with the Corporate Security Team as part of the implementation planning for a new Isilon cluster deployment. The Lead Security Analyst has asked you to discuss the Authentication Sources on your Isilon Cluster. What customer questions regarding Isilon-supported Authentication Sources do you need to be prepared to answer?

Refer to the exhibit. Your customer has three different clusters. File systems on two of the clusters are at 90% full, and the largest cluster is 10% full. Active data resides on the largest cluster. The customer has five different node types totaling 2PB and 54 nodes. Nodes from left to right are as shown: 1.X200 2.12000X 3.36000X 4.NL108 5.108NL They have a Smartpool license and believe that tiering data would help free up needed space. After talking with the customer and explaining the use of SmartPools, how would you recommend optimizing utilization across all of the nodes that the customer owns?

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?

Which level of control does RBAC provide for cluster administration roles?

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 received a critical task that requires immediate analysis of system performance. Captured data will later be processed by MiTrend, but a current assessment is not available. Which utility will quickly provide IOPS associated with reads and writes, CPU utilization, and I/O scheduler wait time?

An Isilon has 3 NL410 nodes with 36 2 TB HDDs each. VHS is specified as 3 virtual drives or 15 percent of the node pool. Which configuration would be used as reserved space for VHS?

What is a Shadow Store used for in Isilon OneFS?

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 system administrator has identified a problem on the cluster and has opened a service request on support.emc.com. They initiate isi_gather_info but it is taking a long time to complete. What can they do to speed up the completion of for the next run?

A customer plans to consolidate 200 TB of digital images and video content. Performance is important for recently created files. However, the customer wants any content that has not been accessed within 30 days to be stored in the cluster at a much lower cost because performance is no longer critical.Which Isilon configuration should be recommended?

Which impact policies are available on an Isilon cluster?

You are setting up SmartPools on the cluster. Which Microsoft Windows system tool will illustrate the difference in performance experienced by clients connecting to different tiers of storage?
