I agree with Greg - For ZFS, I'd recommend a larger number of raidz
luns, with a smaller number
of disks per LUN, up to 6 disks per raidz lun.
For 6 disks, 3x2-way RAID-1+0 offers better resiliency than RAID-Z
or RAID-Z2. For 3-5 disks, RAID-Z2 offers better resiliency, even
over split-disk RAID-1+0.
This will more closely align with performance best practices, so it
would be cool to find
common ground in terms of a sweet-spot for performance and RAS.
It is clear that a single 46-way RAID-Z or RAID-Z2 zpool won't be
popular :-)
