Which data access pattern uses moderate prefetching?
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?
How does Isilon SnapshotIQ use storage for snapshots?
When a Gen 6 Isilon cluster receives a file to be stored, which node(s) performs the FEC calculation?
A customer is making a decision between Isilon and a competitor’s offering. They currently have 100TB of usable capacity and are forecasting 100% growth per year for the next three years, which will require them to lease additional space in their co-located data center. The CFO finds ROI and TCO to be important decision criteria.
Which statement best emphasizes the value of Isilon for this customer?
Your customer has an Isilon 4-node X400 cluster used for home directory use, and has since updated to OneFS 7.0. The HR and Legal departments have been very strict about using only dedicated file servers that are part of a single, isolated, untrusted Active Directory domain. Their filer has been out of maintenance, and fears are being raised that, due to the age, it may fail at some point.
What could the IT department do, to allow the HR and Legal groups to provide file share services, with minimal impact to their other application permissions?
A company wants to reduce the footprint in their data center. They recently completed a proof of concept with Hadoop using Direct Attached Storage (DAS) for their Big Data initiative. You have determined that incorporating an Isilon cluster into their Hadoop environment would help in reducing this footprint.
Which Hadoop components can be consolidated onto the Isilon cluster to reduce the footprint?
What is the smallest unit of data that Isilon OneFS will write to disk?
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?
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?
