A customer needs to consolidate 300 TB of home directory servers and shared file systems used by development and test groups. A key requirement is to prevent the systems from consuming all free capacity and impacting home directory content.
Which Isilon node configuration should be proposed?
On an Isilon cluster, how much space should be reserved for snapshots by default?
Which tool is used to perform a cluster-wide kernel configuration change on an Isilon Gen 6 cluster?
What is the minimum number of nodes in an Isilon cluster for N+2 protection?
-- 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.
-- Exhibit --
What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?
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?
You are sizing an Isilon Cluster for a new customer. Analyzing their workflow, you determine that they have a small block random read workload.
What is the most important factor to consider when sizing this solution?
When conducting high-level interviews with stakeholders of a project, what are the key questions that should be asked?
If a customer experiences a node failure while at 90% capacity, what is the fastest way of replacing the node in an Isilon cluster?
Given a 5-node Isilon cluster configured with an N+2 protection level, how many nodes can be offline with the data accessible and fully writeable?
You are designing a new Isilon system to store mobile device video clips. The files average 800MB in size and the application team tells you to plan for up to 15,000 new files per day. The product manager for this new service wants enough capacity for the first year and reminds you that response time for storing and retrieving the files is important for customer satisfaction.
The files will be accessed frequently for the first 48 hours after creation, and then very infrequently after seven days. You plan to use N+2:1 protection, and will configure a SmartPools policy to move inactive files to an archive tier within the cluster.
Which configuration best fits the project requirements?
You are sizing an Isilon cluster for a new customer. Analyzing their workflow you determine that they have a large block random read workload.
What is the most important factor to consider when sizing this solution?
Your customer has an Isilon cluster with five X400 nodes and four 72NL nodes. A SmartPools policy moves data to the NL nodes after 60 days of inactivity. The customer wants to expand the archive tier by at least 150 TB and would like to manage a single archive pool.
Which nodes should be added to the cluster?
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?
In what order does an Isilon Gen 6 cluster respond to a client file read request?
Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this.
What are two design impacts this change will have?
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 customer requires a backup to tape of their Isilon cluster. They want advice on whether to implement a two-way NDMP solution or a three-way solution. The front-end network must be used to stream data to the backup solution. Which cost-effective solution will meet their needs?
If an Isilon customer has an environment that requires usage data for chargeback, for analyzing usage trends and for capacity planning, which type of quota enforcing option should be used?
You will be meeting with the Corporate Security Team as part of the implementation planning for a new Isilon cluster deployment. The Lead Security Analyst has asked you to discuss the Authentication Sources on your Isilon Cluster.
What customer questions regarding Isilon-supported Authentication Sources do you need to be prepared to answer?
You meet with the IT Director of a large single site campus. The IT department has recently taken over Physical Security from the facilities department and plans a complete overhaul of the surveillance solution. They are looking to you as a storage architecture expert to provide the correct amount of storage needed. The IT Director asks you what items they need to provide in order to size this solution.
What data do you require from the customer?
A media and entertainment company has asked for help in creating a new Video On Demand (VOD) storage system. The storage would be delivered to 5000 subscribers simultaneously. They would like to store 5000 hours of full length, High Definition (HD) movies.
What would be the best price-to-performance nodes for this solution?
