Saturn X Freeze
The X on Saturn froze unexpectedly (as opposed to those occasions when the display was
expected to freeze, natch). The computer itself was still running, albeit with an elevated load (pushing 4). X permitted itself to be killed, and then I rebooted Saturn just to be safe.
First suspicious behaviour since the memory change.
- buy 80Gb disk
- see if said 80Gb disk works properly in PII/350 shell
- if so, buy second 80Gb disk, mirror them, and use it as the server.
- if not, see if we can squeeze $1000 out of the budget for a new workstation for me, and Saturn gets the 80Gb disk (plus whatever comes in the new workstation), mirrored, to act as a server.
Longer term problem: running all mail and NIS etc on a single box, meaning that the Sun can be turned off most of the time. This is because some estimates of the operating costs of these computers runs to a dollar a day.
I don't believe that.
Power supply peak: 300W == 0.3kW
0.3kW * 24hr/day == 8kWh/day
8kWh/day * 0.05 $/(kWh) == 0.40 $/day
30 day/month * 0.40 $/day == 12 $/month
Well, the units are all inconsistant, but you follow me.
assumes that the thing runs at it's power supply peak constantly,
which we know is a lie. So probably about $10 per month is a reasonable estimate, even adding in the extras for running the switch, firewall, and cable modem. Perhaps there is some kind of gew-gaw I can buy which would tell me how much load is on a single line… since this all goes through a single power cord, it should be easy to measure. You'd think.
Still, I'd like to reduce operating requirements to a single system… that would theoreticaly free up equiptment for Kickstart experimentation.
Somewhere in the budget we need to get another 10/100 switch to replace the one which died… and finding a network wiring rack wouldn't be a bad thing either. Network Supply advertises them, maybe I should see how much they would cost.
