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

A customer has 10 files that are each 10 MB in size. They created two clones of each file on their source cluster. They now want to use SyncIQ to replicate the original files and the cloned files to a target cluster. Excluding protection overhead, how much disk space will the files use on the target cluster?

An Isilon customer's administrator created the nested directory structure, shown in the exhibit, using SmartQuotas. However, a user needs to write an additional 650 GB of data to "/ifs/data/acct/recv". Which steps will enable the user to complete this task?

If Isilon SmartConnect is being configured in a customer environment, which records are required for a supported implementation?

What are common storage array mechanisms?

You have worked with a customer to successfully evaluate their existing server environment using the MiTrend data analysis tool. You have collected the resulting reports and aggregated the data set. You determine the customer's application workload generates a 50:50 read/write ratio with an average of 500K IOPs during peak business hours. Which recommended XtremIO model meets the customer's needs?

If a customer experiences a node failure while at 90% capacity, what is the fastest way of replacing the node in an Isilon cluster?

A customer wants to use their large Gen 6 Isilon cluster for ILM. All of their data is written to and read from a single file pool. They need to use multiple file pools, so slightly used data is stored on less expensive, large disks. Heavily used data is stored on a faster tier. What would satisfy the customer's needs?

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?

Your customer has a new business unit. They are gathering web log files to be analyzed. They are using Hadoop to do the analysis of the logs. The IT department is centrally storing the log files on a five node Isilon cluster. They have enabled the Hadoop cluster to access the files directly. The nodes are X400's with two SSD drives in each node and 96GB of RAM. How many DataNodes does the Isilon Cluster have?

-- 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. What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?

How are files smaller than 128 KB protected?

A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized. They also have multiple Fibre Channel SAN arrays in their environment. They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster. They have discovered that one of the workloads- a SQL database that resides on the X-Series node cluster - is experiencing timeouts due to latency. The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts. How do you advise the customer?

An Isilon customer is experiencing less than expected performance and poor space utilization with their cluster. They are using the X400 nodes with an N+2d:1n protection policy to host web server log data. Upon further analysis, the customer discovers that the web servers write log files 64KiB in size. The log files are then accessed by an analytics application for reporting purposes. What should be done to increase the write performance of the cluster?

If an Isilon customer has an environment that requires usage data for chargeback, for analyzing usage trends and for capacity planning, which type of quota enforcing option should be used?

A Media and Entertainment company is considering changing from 2K resolution to 4K resolution. They will continue to use the DNxHD 220 codec. Assuming everything else stays the same, how will this change affect storage?

Which type of infrastructure does the Isilon scalable appliance connect to on the front-end?

An Isilon customer has two 5-node clusters; one for production and one for disaster recovery (DR). The customer's workflows are replicated to the DR cluster through SyncIQ on individual schedules. They have shut down their production cluster for scheduled maintenance, failed over to the DR cluster, and are currently operating from the DR site. Assume both clusters have identical shares, exports, user authentication. In addition, assume the client applications have been stopped and the DNS re-pointed. What is the easiest SyncIQ Policy method to continue operations on production?

A customer wants to use the Cinder driver to manage XtremIO storage in an OpenStack environment. What is a potential concern?

Refer to the Exhibit. A customer has the following XtremIO environment: Read/write ratio is 3:1 I/O size is 8K Write pattern is random Data is compressible If an application generates 100,000 IOPS of traffic, how many RPAs are needed to replicate the traffic from one XtremIO array to another XtremIO array over IP?

A customer has a supported cluster with the maximum protection level. How many simultaneous node component failures can Isilon OneFS sustain while still allowing full access to the entire file system and dataset?
