Though, you're already doing most of their recommended practices. They claim that "Lab testing had shown that Solaris and AIX may perform slower than other operating systems", which is amusing / irritating. How many striped lvs did you end up with? I have hesitated about making big striped LVs out of fear that I'll bottleneck my clients because I'll only have "a few" threads free to process data. Consequently, my striping has been in terms of defining N DISK volumes per stgpool, where N is the number of underlying RAIDs. But that is a pain in the patoot in many ways, especially for reorganization. I've considered making a bunch of striped LVs (as in, a hundred or so) and doing it that way, but I figured that would add up to thrashing the heads. - Allen S. Rout
