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
Where does Endurant Cache stage its write cache?
- A . SSD
- B . DISK
- C . NVRAM
- D . DRAM
What is an accurate statement concerning shared journals on node pairs?
- A . Requires a minimum of 4 nodes
- B . Directly linked through mid-plane of the chassis
- C . When a node boots, it first checks its paired node’s resources
- D . Nodes 1 and 3 and nodes 2 and 4 form node pairs
What must be configured on a PowerScale in order to store only the customer presentation PPT and PDF files on the cluster and the external repository?
- A . Enable file filtering on the share repository, denying access to PDF and PPT file extensions.
- B . Enable file filtering on the share repository, allowing only write PDF and PPT file extensions.
- C . Enable file filtering only on the share repository, allowing only read-only PDF and PPT file extensions.
- D . Enable file filtering only on the share repository, denying access to PDF and PPT file extensions.
What is the behavior of the Isilon time and date settings and what is the best practice?
- A . SMB time sync takes precedence over the NTP service SMB time is enabled by default on the cluster Best Practice: do not use SMB time, use NTP for cluster and Domain Controller
- B . NTP service takes precedence over SMB time sync SMB time is enabled by default on the cluster Best Practice: do not use NTP time, use SMB for cluster and Domain Controller
- C . NTP service takes precedence over SMB time sync SMB time is enabled by default on the cluster Best Practice: do not use SMB time, use NTP for cluster and Domain Controller
- D . SMB time sync takes precedence over the NTP service SMB time is not enabled by default on the cluster Best Practice: do not use NTP time, use SMB for cluster and Domain Controller
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.
In an 18 node Isilon cluster with the default protection setting, what is the layout of a 128 KB file?
- A . N+3d:1n
- B . 3x mirrored
- C . N+2d:1n
- D . 2x mirrored
