Time for some hardware changes --- part 1
As I mentioned in part 0, the story will now continue with updates here on tumblr. Decision 4: Today I ordered two 8 port 1000-base T switches with PoE. One of them will replace the big 50-port switch in my 19" rack to save energy. I suppose, it will cut the energy to 1/5. The other will go parallel to the the 16 port switch in the home office, so I can switch off the big switch too, if the office is not active and the small switch can serve the primary IP phone with power, so I can remove the power supply from the phone itself (it is a small saving, but I take every milliwatt). Decision 5: Addtionally I transferred all SIP-accounts from the secondary IP phone to this one, so I could remove this phone. I can only talk on one phone, so away with this! Decision 6: Exchange the fridge. I was thinking about this earlier, but now its decided. My fridge consumes (I have measured) about 700 kWh per year... new ones promise with the same volume below 170 kWh/year. But I'm not sure, when to order... I wait for a bargain. Decision 7: I will remove the gateway server and transfer this services to the fileserver. The fileserver was build last year with focus on energy saving and the gateway server is very old and ineffective. Why running both? But I have to consider security reasons a little bit more to have DMZ and VPN network services and internal services (e.g. file service) on the same physical device. But even when I migrate the services, my personall infrastructure is a far lot more secure as in the most companies I know... so maybe not worth getting headache. Read the full article
