Exam 6: Isilon Solutions and Design Specialist for Technology Architects

A new VPLEX system has been installed that uses ESRS. The firewall administrator has opened ports 25, 9010, and 5901 between VPLEX and ESRS. A support ticket is logged. While trying to troubleshoot, the technical support engineer cannot access the GUI of VPLEX. Which port needs to be opened on the firewall?

LUNs belonging to an ESXi cluster were encapsulated behind VPLEX. What information must be shared with the ESXi administrator so that they can re-discover the datastore and the RDM LUNs?

Which command collects the most recent performance statistics from all VPLEX directors?

When is expanding a virtual volume using the Storage Volume expansion method a valid option?

What happens to global cache size if a director fails and is removed from the cluster?

A storage administrator has been tasked with migrating a Microsoft SQL Server and its native EMC VNX LUNs behind a VPLEX Local cluster. However, in planning for future application growth, the database administrator wants to be able to expand the storage volumes. Based on this information, which geometry should be selected during encapsulation?

Which VPLEX component can determine the difference between a partition and a site failure of a VPLEX Metro configuration?

-- 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. Based on the meeting with the customer, which Isilon cluster configuration would you recommend?

How are physical ports numbered for each I/O module in VS6 VPLEX hardware?

Why is it EMC best practice that each back-end LUN has a connection to all the A-directors and to all the B-directors in the VPLEX cluster?

What is required to add a RecoverPoint cluster to VPLEX?

A storage administrator has created a VPLEX distributed device. The administrator is performing application tests on the host utilizing the distributed virtual volumes. During testing, some of the write response times appear to be elongated. What is a characteristic of distributed devices that explains this issue?

How can a VPLEX storage administrator manage array-based attributes?

Your customer is looking for a storage solution that will be able to store seven million 3 MB files which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1 Gbps. What would be the best solution for this network configuration?

At which layer of the director IO stack are local and distributed mirroring managed?

What is a consideration for using a VPLEX logging volume?

What is the purpose of issuing the batch-migrate check-plan command?

In a VPLEX Metro, what factor has a direct impact on VPLEX performance with respect to WAN bandwidth?

A storage administrator wants to view additional performance metrics for their VPLEX cluster. The administrator runs the report create-monitors command to help with this task.

You have 1000 users for an application that reads and writes files averaging between one and four MB in size. Each user requires 24 MB of RAM. You want to add another 1000 users for this application, and in preparation for them, you run the isi statistics command. You discover that the average CPU utilization is 20%; aggregate throughput averages 700 MB/s and the disk QueueD average is 1.5. Your cluster currently has five X200 (12 GB RAM, 1 TB drive) nodes, uses N+2:1 protection and 1 GigE networking. What should you do to accommodate the next 1000 users?
