Re: FTTH Internet speed drop - started last month

said by doubleohwhat:

So I'm doing a complete overhaul this weekend to reduce the amount of hardware and overall power consumption (currently at 1,240 watts).

My rule of thumb is that AC power is about a dollar per watt per year.

Sounds about right. My power bill is by far my largest bill each month.

You've got somewhat expensive power rates. That would come out to around 10cents/kWH. I average around 7cents/kWH. A while back I pulled the specs on my equipment and added it up and I'm around $375/year on the nominal draw. Thankfully I'm not running servers at home anymore. I've contemplated building a rack mount host to run VMware ESX on for a decent FreeNAS box and to host a Linux box for some services. I will do it eventually, once I have enough of a need. Hopefully I can find or piece together a system that averages a low enough power draw to keep the cost reasonable but still has enough horsepower to perform reasonably well. I'd definitely include a RAID card and 3 of the largest 5400 RPM drives I could find, as well as a significant amount of memory.

I would love to have your power rates. The lowest tier of power is 13-14 cents/kWH with PG&E. The rates ramp up significantly as usage increases and subsequent placement into higher tiers.
