PERC RAID init speed slowness

I recently bought two identical PowerEdge T640 with internal PERC H730P 
Adapter and eighteen 16TB disks.  I created a 17 disk RAID6 with 1 hot 
spare on both.

On the 1st server I created the RAID Sunday (May 16 16:20:13)
and on the 2nd server I creatd it Monday (May 17 11:23:45)

As of right now the 1st server RAID reports 9% complete while
the 2nd server RAID reports 50% complete.   Which is crazy since
the 1st has been running almost half a day longer!

I checked the BGI rate on both which are both the default 30%

There is no other activity on either server going on as I am
waiting for the init to finish.

I can find no errors or other clues in the logs I know to check.
All other aspects of the RAIDs are good (all disks report good)
A comparison of 'perccli64 /c0 show all' between the two shows
no differences in any settings.

Simple random-write 'fio' tests on both show slightly slower
on the first server compared to the second but only about 10-15%

Anyone have any clues as to why the huge slowness on the
initialization on the first server?
