Meanwhile, I've found a customer's system, where we have a MegaRAID SAS 1078 with a 6-disk RAID 6 volume, and this one delivers 54MB/sec, which really puts the SmartArray controller to shame at its measly 4MB/sec. I just want to stress that our machine with the SmartArray controller is not a cheap old dusty leftover, but a recently-bought (December 2011) not exactly cheap Blade server, and that’s all you get from HP. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
