A customer currently has 10 HPC nodes. They plan to purchase a 5-node Isilon X400 cluster for an HPC application running on Linux. They will persistent mount the Isilon cluster through NFSv3.
Which recommended configuration addresses the customer's requirements for high availability and throughput?

An Isilon customer created a SyncIQ policy to replicate data from a primary cluster to an offsite secondary cluster. The primary cluster becomes unavailable, and the customer has completed a failover onto the secondary cluster.
The primary cluster becomes available again, so the customer would like to fail back data to the primary cluster. The failback process does not replicate data.
What is the most likely reason the failback policy does not replicate data to the primary cluster?

Your customer is looking for a storage solution that will be able to store seven million 3 MB files which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1 Gbps.
What would be the best solution for this network configuration?

A customer has an SMB file directory with 375 TB of data on the primary cluster with a protection level of N+ 3:1. They want to replicate this directory to the secondary cluster.
The customer would like information about the possibility of setting protection levels on the target cluster.
What information can be provided to the customer about the protection level for the target directory?

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?
