[mythtv-users] Proposed future power saving networked configuration (0.22 in mind)

[Brian Edmonds]

There's always the issue of stability. Drivers for tuner cards are more
likely to have bugs, in my experience, that hang or crash your system, or
just need upgrading more often. Being able to put the master together with
the database on a stable fileserver, and farm recordings out to lightweight,
easily rebootable slaves could be an advantage.

Why wouldn't you want your master to be on your fileserver? That seemed like
the logical setup to me, and I've only had to add 1 sata controller since I
built the thing (well, and the 3 IDE controllers that *used* to be in there,
but I replaced ALL those drives with just 4 sata drives).

I guess my question is simply, why would you want a tunerless master if you
plan on running multiple slave systems, and your master is connected to an
HDHR that it isn't powering anyway? Of course, I'm not against this, there
seems no logical reason not to be able to run a backend without a tuner for
scheduling, transcoding and comm flagging and such, I just don't see a need
for a tunerless master backend myself.

Though I think your numbers were pretty arbitrary, I definately see merit to
WOL Slaves. I don't see the power savings that removing a couple tuners in
your masterbackend being nearly as high as the return on having 2 or 3 extra
tuners in your slave backends turned off when you're not using them (as well
as the system).

See, again, why does the vm on the fileserver have to be the slave?

This sounds really cool, perhaps you can reply to me off list and describe
more how you've got it set up?

But it's worth it... them greedy utilities!  ... Well, actually, I believe
that as a people, globally, we need to stop depending so much on utilities
and corporate conglomerates and produce more of our own energy. Electricity
is so easy to make, and there's so many ways to make it... it's just a shame
that the inverters to take it from batteries and make it a nice pretty 60hz
(or 50hz) sine wave are so darn expensive. But now I've gone on a tangent.
