How does Isilon SnapshotIQ use storage for snapshots?

What is appropriate for capturing packets for later analysis of I/O request sizes and randomness on Isilon clusters?

A customer has 10 files that are each 10 MB in size. They created two clones of each file on their source cluster. They now want to use SyncIQ to replicate the original files and the cloned files to a target cluster.
Excluding protection overhead, how much disk space will the files use on the target cluster?

Which impact policies are available on an Isilon cluster?

A potential customer uses a solution from an EMC competitor for NFS storage in their main data center. The existing arrays are five years old, and the customer would like to consolidate them into a single new system.
The entire workload is generated by eight Linux hosts connected to the arrays that process video files. The customer informs you they are not able to collect performance information from the existing arrays.
Which tools can capture the workload requirements?
