Which level of control does RBAC provide for cluster administration roles?

Your customer has an existing Isilon cluster comprised of five NL-Series nodes. They have a new project that will quadruple their current throughput requirements. Upon reviewing reports in InsightIQ, you see that the aggregate external network throughput is peaking at 600MB/s. The customer states that data is only active for the first 7 days, but they keep it indefinitely.

Which recommendation best supports their growth requirements?

Three jobs are running, all with a priority of 5. A new job with a priority of 6 needs to be run. What happens?

Refer to the exhibit.

Which tool was used to create this output and which line item counts the metadata read operations occurring in the file service?

An Isilon customer experienced a node failure. The failure requires that the affected node be permanently removed from the cluster. What will occur in the cluster upon failure of the node?

Which block size does Isilon SyncIQ use to transfer data?

For concurrent I/O, how do SmartCache and Endurant Cache differ?

A customer has a cluster running with a single access zone and serves multiple internal departments. The

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?

-- Exhibit --

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 Illumina 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.

Before making any changes, the customer would like a graphical presentation of their existing array performance to present to management.
