<br>><br>> -Jeff<br><br></blockquote></div>I'd like an estimate of what your power bill is every month with that many computers in your house.<br>By your network topology I count at least 8 always on computers - but from reading your blog it sounds like more. I'm all for recycling older hardware, but new hardware is a one time cost as opposed to handing the utility company your bank account every month.
<br><br>I feel I could get the same or better performance and only use 3 24/7 boxes.<br>I'd consolidate my nas boxes into one large system. I'd use
dual bonded gigabit for it especially since it already appears you have
a nice gigabit switch that probably has the option to do link
aggregation. With port multipliers you can put in up to 20 sata drives in a cooler master stacker case (or add some externals for more if you need it). The sata port multiplier code will even be native in the linux kernel starting in
2.6.24. You would also save more money by being able to invest in a really effiecient power supply (750 watts or so should do it with an efficiency rating over 80%). Throw a q6600 in that new nas box, and a 2.5" low power
usage notebook drive as the main drive and it could also be your main
myth backend that does all your transcoding/commercial detection. It would also have no problem
handling your dns/dhcp/mail/http/asterix(not sure you have asterix) server duties. That would allow you to
drop 4 constant use, power sucking computers
and would probably pay for itself in a year due to lower power bills.<br>
I also feel looking at your network map that you could drop a few slave
backends and not lose any performance. I don't see the need for an
entire slave backend for just 4 cameras. If you don't want to use the
cheap 8 input pci/pci-x camera recording cards, you could throw in 4
pvr-500s and accomplish the same thing you have now with one box. Add in one
other slave backend to do all your satellite receiver recording with either 4 pvr 150s or again some pvr-500s.<br><br><br>
