1. The answer to my first question about mirroring swap was uniform by
everyone. Mirror swap so in case that I loose one hard drive the machine
will keep on running. Also its easier to maintain the raid and faster.

2. The issue of booting a damaged raid is still somewhat unclear but as
soon as I set it up I'll test it and have the right idea.  According to
some it will boot fine and run (which I doubt). And according to others a
failed raid will not be a functional boot device. Henrik mentioned that I
should be able to boot into a single user mode with failed raid and fix
the raid or diassembel it and then continiue into multi user mode.

Also couple of people sugested using the newest Solaris distribution and
patches for Netra network cards.

thanks
