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

A customer's storage administration team wants to receive e-mail notifications when the XtremIO cluster detects an issue of major seventy. The customer has successfully configured and tested the e-mail server in the XtremIO GUI. However, the e-mail server is not receiving the expected notifications when major severity issues appear. What is the cause of this issue?

How many impact policy levels are available when configuring Isilon jobs?

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 100 TB of RAW capacity. They want to consolidate their PACS, file shares and home directories onto one cluster and require very fast enumeration of the directories. The following are the notes from meetings with the department heads. Which is the best cluster configuration that meets the customer's requirements?

Which Isilon feature increases available space by consolidating copies of identical blocks of data?

Three jobs are running, all with a priority of 5. A new job with a priority of 6 needs to be run. What happens?

What is the relative latency of a cache hit to L1 cache compared to a hit to L2 cache in an Isilon cluster?

Which node type provides CPU, memory, and Fibre Channel connectivity?

Your customer uses an existing Isilon cluster consisting of five NL-Series nodes to source broadcast media files for playback and streaming.The customer reports that the playback pauses and stutters regularly. It has been confirmed that there are no network or playback system issues. Which of the choices listed is the appropriate choice to address the playback issues?

A four node F800 Isilon cluster running OneFS 8.2.1 has a dedicated subnet and IP pool for SMB data traffic. SmartConnect Advanced license is applied. The SMB IP pool consists of LACP aggregated. 10GigE interfaces from all the nodes. What is the maximum number of SmartConnect Service IPs recommended for the SMB subnet?

A customer wants to add Unix users to their cluster, and requires that NFS access be fault-tolerant. What would you recommend?

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?

Which level of granularity does XtremIO deduplication run?

Which block size is used by Isilon SyncIQ to transfer data?

An Isilon has 6 X410 nodes and 4 NL410 nodes. How many job engine directors does the cluster have?

A potential customer has about 540TB of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. They have LDAP and Active Directory authentication and primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing. Which tools would you use to gather information to do your Isilon sizing?

An Isilon customer wants a job to periodically validates the checksum of every block in the file system. What should be recommended to the customer?

When using a 10 TB single X-Brick, what is the minimum amount of data that should be written during the Fill phase of the PoC Toolkit?

The security team at a customer site has created a new requirement that in-flight replication traffic must be encrypted end-to-end. The customer is running OneFS 8.2.1 on their cluster. What encryption protocol versions does SyncIQ support?

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?

-- 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?
