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? --------------------------------------------------------------- Paul Raines http://help.nmr.mgh.harvard.edu MGH/MIT/HMS Athinoula A.
