The log files are then accessed by an analytics application for reporting. What should be done to increase write performance of the cluster?

A) Change the protection scheme to a mirroring policy.
B) Add A-Series performance accelerator nodes to the cluster.
C) Add S-Series storage nodes to the cluster.
D) Add SSDs to the X-Series nodes in the cluster.

Question 70

-- 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. The CIO approaches you with a new requirement. They would like to reuse the tape library that was previously used for archiving to now be used to back up some of their data. What do you recommend to the Director of IT as the best architecture to achieve this goal?

A) Connect the Tape Library via Fibre Channel to the Isilon cluster and use a third party backup software to initiate an NDMP backup to an accelerator.
B) Implement a Backup Accelerator and use the internal backup software within the Isilon cluster to move data to the tape library.
C) Use a Backup Accelerator with SyncIQ to push the data to the tape library via the Fibre Channel ports on the accelerator.
D) Use a third party backup software and have the Isilon cluster convert the data to LTFS so it can be stored to the tape library.

Question 71

-- 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. 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) InsightIQ
B) isi_netlogger
C) tcpdump
D) netstat

Question 72

A customer plans to consolidate 200 TB of digital images and video content. Performance is important for recently created files.

Question 77

A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets. There is very little space available in the customer's datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives. What Isilon capabilities can address the customer's concerns?

A) Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID rebuilds. N+3 and N+4 Protection Levels exceed traditional RAID6 availability. Data redistribution runs faster with more nodes in the cluster.
B) Proactive hot sparing eliminates most drive rebuilds. Endurant Cache reduces the overhead for write operations.
C) Data recovery is consistent, taking the same amount of time regardless of cluster size. Isilon 'short strokes' 4TB drives to reduce rebuild time.
D) Isilon nodes have more drives per rack unit so fewer shelves are required.

Question 78

Your customer has several departments that want separate access to the cluster so they can use their individual authentication methods. Two of the departments will use NFS and two will use SMB to access the cluster. What would you recommend?

A) Create two separate access zones for the SMB clients, and use the System zone for the NFS clients.
B) Create separate access zones for both the SMB and NFS clients.
C) Create two separate access zones for the NFS clients, and use the System zone for the SMB clients.
