Time to run DPACK-F @ Isilon

I know this is a open ended question with lots of variables, but does we have any time estimates to run a DPACK-F against Qty 7 Isilon X410 nodes ~ 700TB of space?  We do not have file count or avg size.  Partner is pushing client for a DPACK-F scan and pressuring us for times.  Even some general estimates would be helpful.

Thanks,
