NO.28 A large retail customer is using their Isilon Gen 6 cluster to store receipts. The resulting workflow data consists of only small files. What configuration change is recommended for this environment to reduce CPU overhead?
Response:

NO.29 We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200 TB of capacity and run on a 1 Gbps network.
They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process dat a. They would like to expand Isilon to 2 PB of active data and 1 PB 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?
Response:

NO.30 A company wants to have their new PowerScale Gen6 cluster benchmarked for a UNIX environment. What commonly available open-source tool is typically used to test PowerScale cluster performance in this environment?
Response:

NO.31 After raw events are processed by the CELOG coalescers, what happens to the data?
Response:

NO.32 A hospital has decided to add Next Gen Sequencing (NGS) as a clinical option. The hospital’s cancer diagnostics team wants to know if the current Isilon cluster being used for their PACS environment could support their NGS environment.
They are concerned about one workload interfering with the other. The account team has determined the existing hardware meets their requirements. Which Isilon features should be recommended to optimize individual workload performance?
Response:

NO.33 At a minimum, how many connected and available nodes are required to maintain quorum in a 25- node cluster?
Response:

NO.34 A company currently has numerous file servers providing home directories for its employees. Some departments have their own file servers. All corporate users authenticate using Active Directory. The engineering department has their own untrusted AD domain for their file servers.
The company is looking for a consolidated solution that requires minimal changes to the environment, and that creates a single namespace for the home directories.
What is the recommended solution that will meet this company’s requirements?
Response:

NO.35 A customer’s cluster contains three X200 (24 GB RAM, 3 TB drives) nodes, and three X400 (48 GB RAM, 1 TB drives) nodes. All nodes are configured in a single pool. All data is protected at N+2. After upgrading OneFS to 7.0, the Isilon Web interface indicates that files are not fully protected.
What should be done to correct this situation?
Response:

NO.36 An architect is designing a new cluster. The cluster contains H500 nodes to store home directories of 2000 users and A200 nodes to store backups of VMware virtual machines. Which data access patterns should be used?
Response:

NO.37 There is a concern that there are not enough physical switch ports available for the Isilon cluster in a new implementation with SMB and ICAP requirements. What course of action should be taken?
Response:

NO.38 What happens to worker threads running on the same node when there is an excessive number of workers running at the same time?
Response:

NO.39

As part of a proof of concept, you are investigating disk performance statistics using the “isi statistics” output. After reviewing the “TimeAVG” column shown in the graphic, which information should be provided to the customer?
Response:

NO.40 When designing an Isilon cluster for content creation workflows in the Media and Entertainment (M&E) vertical, what type of workflows must you consider?
Response:

NO.41 You have had several discussions with your customer in the processor design industry. They have stated that they want a Scale-Out NAS platform for their design environment.
Their most significant responses were “We have 125 design engineers accessing large diagrams and we need high throughput to support them. Can we also get the highest performance available?
We need to stay ahead of our competitors.” Other areas you discussed were their data retention policies and workflow after the chip design is completed. They plan to archive the design files but the files must stay on line.
What is your initial node recommendation?
Response:

NO.42 In OneFS 7.2.1, which job engine job will override and pause all other jobs when triggered by an event?
Response:

NO.43 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?
Response:

NO.44 You are asked to size a cluster for a file sharing environment. nfsstat indicates that 75% of the requests are namespace operations (e.g., GETADDR, SETADDR). There will be 8,000 active Linux users, connecting over NFS.
Which cluster configuration would you recommend?
Response:

NO.45 An Isilon cluster is configured with SmartConnect zones using dynamic IP address allocation. Failback is enabled. What happens to the IP address in the event of a node failure?
Response:

NO.46 Which operational consideration is used in the Isilon Sizing Tool to determine the recommended data protection?
Response:

NO.47 An administrator recently installed InsightIQ to gather cluster statistics, and wants to look at file system usage (such as the number of files in a directory). However, currently no file system statistics are displayed in InsightIQ after 24 hours. Use of the cluster is moderate, and occurs 24 hours per day.
What job for InsightIQ should the administrator modify to successfully report these statistics?
Response:
