… continuing a story, that began on Facebook. But I mentioned in my last post, I dump Facebook. So we need a transistion of the information to tumblr…<\/p>\n
{TL;DR}<\/p>\n
I’m angry about my energy costs.<\/p>\n
I have 5200 kWh \/ year, which is here in Germany the amount of a 5 person household. I’m single, but IT-nerd.<\/p>\n
{end TL;DR}<\/p>\n
So I have some infrastructure in company design and size:<\/p>\n
Two internet connections (1 DSL 100Mb, 1 LTE 40MB) connected via 8 port 1000-base T switch to a gateway server (DMZ) with firewall and vpn to connect over internet, another vpn to my big servers in the data center, and some other services.<\/p>\n
This server is connected via a second network interface to a 50-port 1000-base T switch (internal zone), there attached a fileserver with NVMe SSD boot and storage RAID10 with 4 Terascale datacenter drives. Also attached two NAS (but 99% switched off) for a third backup level. Also attached a WiFi Accesspoint with (net) 800 Mb, bridging to two other WiFi Accesspoints in my appartment (for my ESP-32 devices WLAN).<\/p>\n
Also attached two other switches:<\/p>\n
One of them is an 8 port 1000-base T for my „free time PC“ (so I don’t need the big PC for fun after work), an IP phone and an („oversize“) ink printer with scanner. That was the first decision<\/strong> for energy saving. The additional PC saves a lot of energy costs instead of the big one. It is consuming with all its environment (two screens, external speakers, graphic tablet, pen tablet screen) 75% of the the big PC alone (see below). Second decision:<\/strong> All these devices are connected to a real power switch via radio, so everything is really switched off, if not in use. So no consuming energy in standby mode.<\/p>\n The other switch is a 16 port 1000-base T in my home office. The 16 port switch has connected my dev PC (2 Xeon CPUs, 96GB RAM, SSD, 6TB net via LSI SAS hardware RAID10 and a lot of USB 3 ports), the dev PC has 1 x 48″ UHD curved & 2 x 40″ UHD curved (all with network ports). I can connect another 5 screens… but mostly I work witt only two of the big screens… they are representing the usage of 8 normal HD screens… ). Ok. There is another smaller PC connected to the switch for administrative work (2 Xeion CPUs, 24GB Ram, SSD, some TB HDD. Then two network printers, a b\/w HP LaserJet and an HP PageWidth inkjet printer. Then two IP-phones. And an UHD bluray player with network connection. Third decision<\/strong>: All of this – except the network switch and the phones are connected to a radio controlled powerswitch as well.<\/p>\n Someone wondering about my energy costs?<\/p>\n But with these decisions above, I came from 14,5 kWh\/day to 13,4 kWh\/day.<\/p>\n You are up to date now.<\/p>\n Time to make more decisions… in part 1<\/p>\n","protected":false},"excerpt":{"rendered":" … continuing a story, that began on Facebook.
