Hello list;  is it possible with OmniOS to have a multi-way mirror with
one disk being an SSD and the rest magnetic;  then to tune ZFS to
perform all reads from the SSD?  for the sake of performance.  The
default case is round-robin reading, which is the best if all disks are
of approximately equal performance, especially if they're on separate
controllers.  But SSD changes that.
