Interestingly, the P400’s successor, the P410 does recognize a setting that the P400 lacks, which is called elevatorsort. It sounds like this could make all the difference. Unfortunately, the P400 doesn’t have it. I don’t have a P410 with more than 2 drives to test this, but some effect should definitely be measurable. Since this finding has piqued my interest again, I’m willing to invest a little more time, but I’m completely occupied for the next few days, so it will have to wait a while. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
