Hi. If I am using slightly more reliable SAS drives versus SATA, SSDs
for both L2Arc and ZIL and lots of RAM, will a mirrored pool of say 24
disks hold any significant advantages over a RAIDZ pool?

Hi. As the subject indicates, I'm trying to understand the impact of
the ZFS prefetch issues and if they only impact a local zfs

Fibrechannel.
Can anyone comment on this?

Hi;
You may be hitting a bottleneck at your HBA. Try using multiple HBA's or

I'm pretty sure it's not a HBA issue. As I commented, my per-disk
write throughput stayed pretty consistent for 4, 8 and 12 disk pools
