I have a “rack” that pulls between 350-400W average 24/7. I’m looking for suggestions to bring the energy consumption down by doing some consolidation. I’m not against putting all my eggs in one server if it saves me on the electricity bill. A lot of what I’m using are old components I grabbed from work over the years, so I didn’t go for efficiency when putting it all together. The switches and APs I’m not too interested in changing but I’d expect I can probably do better with the PFSense box and the 2x Z-Books. Currently I have the following,
- ISP Modem - Bell Gigahub
- PFSense Router (i5-4570S, 16GB RAM, 2-Port 2.5G QNAP NIC) ~40-50W Average. Configured as PPPoE with a 3Gig connection so it does need a bit of CPU to get the full speed.
- Home Assistant - Raspberry Pi 4
- PiHole DNS - Raspberry Pi Zero
- HP Z-Book G2 (i7-4910MQ/32GB RAM/Quadro K2100M) - Plex Server/VPN/Torrent Box (w/ 5x External 3.5" Drives in enclosures - Up to 7 or 8 1080p Plex Streams (worst case). Usually 5 or 6 of them are Direct Play with 1-2 being Transcodes.
- HP Z-Book G2 (i7-4810MQ/32GB RAM/Quadro K2100M) - Blue Iris Surveillance Software (w/ 2x External 1TB Drives) - About 20%-35% CPU usage.
- 1x Mokerlink 5-port 2.5Gig Switch
- 2x TP-Link TL-SG105 Managed Switches
- 1x TP-Link TL-1005P 5-Port PoE Switch (Running 4x Reolink RLC520A cameras) ~40W
- 1x Asus RT-AX88U as Access Point
- 1x Linksys WRT1900ACS as AP for IoT Devices
- NAS - Synology DS920+ w/ 4x 4TB Internal Drives and 1x WD External for Backup (Running the following docker containers, PiHole, Bitwarden, Calibre, Calibre-Web, iPerf3, Grafana, Portainer, Prometheus).
Thoughts?
