This is what I was trying to find out. I guess I just have to 
test it empirically.

My application is to stick 2x SSDs into a SunFire X2100 M2,
without resorting to splicing into power cables and mounting
SSD in random location with double-side sticky tape. Depending
on hardware support I'll either run OpenIndiana or Linux
with a zfs hybrid pool (2x SATA drives as mirrored pool).

Eiter way I'll know the hardware support situation soon
