A customer plans to deploy N+2d:1n protection on a 5-node Isilon cluster. How much capacity will be used to store a 320 KiB file?
A telecommunications company has a substantial amount of data. This data is being created by network elements within their environment.
The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records.
In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs.
After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment.
Considering the customer's requirements, which is the best node type for the Isilon cluster?
A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT you learn that the company is considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.
Which Isilon capabilities would show a better ROI for the customer?
An architect is designing a solution for a new customer. The customer is going to use the cluster to store a
large number of files that will be accessed by many users.
What IO optimization should be used and what kind of prefetching will take place?
A customer is having problems writing data to their Isilon cluster. You have checked all network settings and authentication sources. No errors are reported from the cluster. The customer runs tcpdump and sends the results to you.
Now that you have the output, which tool would you use to open the results file?
If a customer experiences a node failure while at 90% capacity, what is the fastest way of replacing the node in an Isilon cluster?
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?
A customer is trying to get Isilon SyncIQ to run on the two clusters they just purchased. However, they are experiencing some problems. They have asked you to explain how the SyncIQ licensing works.
What information can be provided to the customer?
An Isilon customer needs to grant a specific administrator on RBAC privilege. What does the customer need to do?
You are designing an Isilon 5-node cluster configuration for a customer who wants to store user home directories on the new cluster. Each user has 100 small files of 4KB each, 100 medium sized files of 80KB each, and 100 larger files of 512KB each. How much space is occupied by the medium sized files data blocks on an N+1n cluster?
