He's running a 20 data spindle RAID60, across two decent hardware RAID cards each with 512MB write cache, so of course it's going to be much faster than your 4 data spindle RAID6, even with slightly slower spindles. Note that 8x 15K drives in RAID10 on your P410i should slightly surpass Roger's RAID60 performance, ~70MB/s vs 66MB/s. 3x fewer drives for roughly equal performance, but obviously less capacity. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
