You are sizing an Isilon Cluster for a new customer. Analyzing their workflow, you determine that they have a small block random read workload. What is the most important factor to consider when sizing this solution?
A. Headroom-- 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. -- Exhibit -
Before making any changes, the customer would like a graphical presentation of their existing array performance to present to management.
What is the best tool to gather this information?
A. InsightIQYou are involved with a Proof of Concept where the performance is not what you expect. What can you use to collect process stack information and a listing of process waiting on I/O?
A. netstatAllocation schema are being used.
All the Linux clients are accessing Isilon exports using NFSv3 via the `NFS_Pool'. All the Windows clients are accessing Isilon shares using SMBv3 via the `SMB_Pool'.
While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is facing performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4.
What is recommended when creating a new IP pool for NFSv4 clients?
A. Dynamic IP Allocation in the `System' access zoneWhat is the overhead impact on the physical capacity when configuring data protection at +2:1 on a 6-node Isilon cluster?
A. 1/2-- Exhibit -A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400 nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is 60% utilized. Home directories and file shares comprise 75% of the existing content and the remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac clients participating in a single Active Directory (AD) forest.
During a meeting with the CIO and Director of IT you discuss the company's recent acquisition ?an engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX workstations that produce technical drawings which are currently stored on another vendor's SAN solution. The all UNIX environment uses NIS for authentication and name resolution. They do not currently use DNS or LDAP. The engineering company has an old storage system that has been experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO would like to eliminate all tape and recover the data onto disk.
The CIO is concerned about security of the company's intellectual property, especially with the rapid adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and SugarSync. They would like to implement an alternative that provides external file sharing and mobile device synchronization while maintaining security control over the company's data.
The Director of IT reports that users are storing non-work related content on the Isilon cluster. They would like to limit the amount of capacity that each user can consume in their home directory and want to ensure you provide the capability to easily visualize which users are over their allotment.The company's Windows users currently leverage Windows Shadow Copy to recover files that have been accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have the same functionality.
The Director of IT also mentions that users are reporting slow response times when browsing their home directories and shared folders. They are concerned that Isilon cannot scale to support their combined requirements.

Which configuration changes would you recommend for the Engineering users?
A. Direct all clients to use the Manufacturing DNS server and connect NFS mounts to the FQDN of the Isilon cluster.You are designing an Isilon 5-node cluster configuration for a customer who wants to store user home directories on the new cluster. Each user has 100 small files of 4KB each, 100 medium sized files of 80KB each, and 100 larger files of 512KB each. How much space is occupied by the medium sized files data blocks on an N+1n cluster?
A. 9,600KBWhich type of infrastructure does the Isilon scalable appliance connect to on the front-end?
A. EthernetOn an 18-node Isilon cluster with the default protection setting, what is the actual layout of a 128 KB file?
A. 2xA NetApp customer is considering Isilon. They use their filers for UNIX home directories, and would like to see a suggested configuration that would meet their needs. What would you do to help size this cluster?
A. Ask for an autosupport file and upload it to MiTrends to generate a workflow profileNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
