Well the Solaris kernel is telling me that it doesn't understand zfs_nocacheflush, but the array sure is acting like it! I ran the dd example, but increased the count for a longer running time. 5-disk RAID5 with UFS: ~79 MB/s 5-disk RAID5 with ZFS: ~470 MB/s I'm assuming there's some caching going on with ZFS that's really helping out? Also, no Santricity, just Sun's Common Array Manager. Is it possible to use both without completely confusing the array?
