Thanks Mark and Joe.Mark, I think I agree with your assessment of
multiple layers being an overkill. It's up to individual judgment but
for our needs I think IPMI will suffice. Besides the servers I'm
tending to buy do come with IPMI support so that's lucky for. The
chore is just getting it all configured correctly now!
Thanks for all the leads guys!
