If it is HW RAID6 with 10 total drives, then the aggregrate write throughput to the HDDs is about 25% ( 10 / 8 - 1 ) higher than the write throughput that fio measures as going into the HW RAID device. So you'd be looking at about 266MB/s per drive. Which seems unlikely. I wonder if your HW RAID has a large cache. Did you let the fio job run for the full 10 minutes? Because I would expect the cache to fill well before 10 minutes, unless the cache is huge. -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
