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 customer provides the following environment summary from the engineering firm’s recently departed IT staff:
– 20 TB of Home Directory data
– 100 TB of active CAD projects
– 400 TB of archived data stored on tape at an offsite warehouse
What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?
- A . Set up Access Zones on the Isilon cluster using Active Directory (AD) and NIS authentication.
Create directories and apply user group permissions from AD and NIS for each collaboration team. - B . Repoint the engineering users to the Active Directory controller
Add the users to the appropriate Active Directory security group. - C . Upload a collaboration user csv file into the cluster with usernames and passwords for the collaboration directory.
- D . Create a new pool for use by the collaboration users.
Set up Access Zones on the Isilon cluster using AD and NIS authentication.
Which license is a prerequisite for enabling CloudPools?
- A . SmartPools
- B . FilePools
- C . DiskPools
- D . NodePools
What are two output options from the PowerScale cluster events log? (Select 2)
- A . Hardware Issues
- B . OneFS Issues
- C . SMTP Email
- D . Logs
What are three benefits of NDMP multistream backup and recovery? (Select 3)
- A . Backup context is retained
- B . Different backup context
- C . Backup concurrently
- D . Same backup context
- E . Backup sequentially
What happens to worker threads running on the same node when there is an excessive number of workers running at the same time?
- A . Workers are paused
- B . Workers are queued
- C . Impact level of workers is decreased
- D . Priority level of workers is decreased
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 IIlumina 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. The customer has a limited budget.
What would be the best price/performance solution for their active data?
- A . 14 X-Series nodes with no SSD drives and 96GB of RAM
- B . 17 X-Series nodes with SSD drives and 48GB of RAM
- C . 14 NL-Series nodes with 24GB of RAM
- D . 12 X-Series nodes with no SSD drives and 24GB of RAM
A customer has a cluster running with a single access zone and serves multiple internal departments. The clients access the cluster over both SMB and NFS protocols. A department user has been assigned the task of auditing SMB activity and enforcing appropriate quotas for certain users.
How should the cluster administrator grant this access?
- A . Create a secondary root account credential
- B . Create a custom RBAC role
- C . Provide the AuditAdmin RBAC role
- D . Provide the SecurityAdmin RBAC role
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?
- A . Consider migrating data from Isilon to one of their SAN platforms or proposing a new solution to handle the performance requirements of SQL.
- B . Merge the S-Series nodes and X-Series nodes into one cluster, upgrade the 1GbE to 10GbE, and leverage SmartPools to allow for the cluster to determine where data should reside.
- C . Suggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to boost the performance of each cluster.
- D . Recommend they increase the amount of DRAM in the cluster or consider an Accelerator node in order to increase the amount of cache in their cluster.
A new customer is interested in an Isilon Gen 6 solution to replace their sprawling and outdated Linux environment.
Which client tool should you use to establish an estimate of the workload and pattern as an input to the sizing process?
- A . tcpdump
- B . lometer
- C . File System Analytics
- D . iostat
