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?

A customer created one month of snapshots; one snapshot every 8 hours for 30 days on an Isilon cluster using SnapshotIQ. They are now deleting the snapshots randomly and experiencing overhead to the cluster.

How can the snapshots be removed while avoiding the overhead caused by this process?

On an 18-node Isilon cluster with the default protection setting, what is the actual layout of a 128 KB file?

In an Isilon environment, how is InsightIQ installed?

You are helping a customer create a cost-effective Isilon solution. The customer environment includes high IOPS-intensive, random access file-based applications.

Which Isilon storage node type will meet the customer's needs?

What is the recommended namespace path for the access zone on a new Isilon cluster with SyncIQ license?

Which feature of OneFS is used in the Home Directory and File Share vertical to monitor storage and media

clients for optimal performance?

A customer has two data centers (Site A and Site B). There is an Isilon cluster in each data center and they use SyncIQ to replicate data between the two data centers.

You have been reviewing their disaster recovery plan and found the following:

The policies specify that SyncIQ runs a replication job every 2 hours and that the job finishes within 1 hour.

Three additional hours will be needed to get servers and the network redirected to work from Site

What is the Recovery Point Objective in this plan?

When designing an Isilon cluster for content creation workflows in the Media and Entertainment (M&E) vertical,

what type of workflows must 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?
