As a general rule of thumb: if your SAN box will hold strictly familial data ( don't use it for supporting commercial activities / generating financial profits) you should be entitled to freely use OSE 11.

The SAN box has 2 NICs which will be used as 2 different active interfaces with no fail-over/link aggregation configuration.

The whole process of setting up a Solaris operating system won't be explained because it far beyond the scope of this article but here is some pertinent information for SAN setup thematic.

A few points: You can, as an alternative, grab the Solaris Express 11 live CD image and install the system from there.

It is possible that your drives come with preconfigured values preventing them from being spun down before a factory-set delay or being spun at all (experiments with our WD Caviar Green drives are put in standby with a factory-set delay of ~8 minutes).

With the hardware used to build the SAN Box, nothing more than 27W is drained from the power plug when all of the drives are in standby and when the CPU is idle (32% more energy savings compared to the original 40W) :-).

RAID-Z pools can be created in two flavors: A good trade-off here between computational power/storage (main priority)/reliability is to use RAID-Z1.
