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

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?

When designing a SmartConnect IP pool, what is the recommended IP address pool allocation method and protocol state for SMB?

Which Isilon OneFS protection level allows you to withstand two drive failures but no more than one complete node failure?

How many management IP addresses are required on a single XtremIO storage controller?

You have been working with a customer to size a new Isilon cluster for their environment. You recently determined that a cluster with three X400 nodes with 1TB drives and 48 GB RAM would be a perfect starting point for their workflow, but will have extra capacity. The customer just informed you that they have decided to also use the cluster for a small home directory environment and implement SmartQuotas. Which configuration changes should you consider?

An Isilon storage administrator is concerned about capacity after ingesting 200 TB of file data. They recently added more nodes to the cluster and now want to auto-balance it as soon as possible. The cluster utilization percentages for an average 24-hour period are: 45% during 00:00 - 08:59 60% during 09:00 - 17:00 85% during 17:01 - 23:59 The administrator wants to keep cluster utilization at a minimum. Which Impact Policy settings should be used to quickly complete the job without impacting the production workload?

A potential customer uses a solution from an EMC competitor for NFS storage in their main data center. The existing arrays are five years old, and the customer would like to consolidate them into a single new system. The entire workload is generated by eight Linux hosts connected to the arrays that process video files. The customer informs you they are not able to collect performance information from the existing arrays. Which tools can capture the workload requirements?

When using XtremIO storage with Solaris (SPARC), what is the EMC recommended I/O size that will deliver sequential I/O more efficiently to XtremIO?

A customer is interested in purchasing XtremIO for their mission critical database applications that require the lowest possible response times. They have two data centers in which they want to introduce All-Flash arrays. However, they need a way to maintain true active/active access to all databases and application LUNs across both sites. What is the recommended solution to address the requirements?

The protection level of an Isilon Gen 6 cluster with eight nodes has been set to the default protection level. How many failures are tolerated without data loss?

What determines the number of job engine workers assigned to a task?

How much space is consumed by a 4 KB file when the file data is written to the Isilon cluster?

How many files can reference a single block within a shadow store?

Which license is a prerequisite for enabling CloudPools?

Your customer is moving from a Restaurant/Bar business model to a Restaurant/Casino business model. You are helping architect the upgrade of a current 4-node X200 48 TB Isilon cluster, with 65% utilized for their video surveillance operations. They wish to achieve the following: Upgrade from 1280 x 720 resolution, with a 15 days retention policy, to 2048 x 1536 resolution with a 30 days retention policy. What is the minimum number of nodes of the same type will you need to add in order to meet the required changes and not exceed 70% raw capacity?

If a client is mounted to the sixth node in a 20-node Isilon cluster, how much memory cache can that client leverage assuming each node has 8 GB of memory cache?

Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this. What are two design impacts this change will have?

An Isilon customer wants to more effectively manage their storage and thereby achieve performance improvements. Which tool will help improve workflow performance on their cluster?

A customer wishes to back up their Isilon cluster via NDMP using a software package that supports NDMP connectivity. The backup process will require the cluster to create a point-in-time copy of the directory to be backed up. Which OneFS feature(s) will need to be licensed?

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. Considering the customer's requirements, which is the best node type for the Isilon cluster?
