Homeproduction! + +If you're reading this and have no idea what a 'homelab' is, it's a hobby for system administrators whereby we set up our own "lab" environments at home, to play around with and generally learn on. Some are small, just a home server and a switch, and some are basically mini-datacenters. Mine's closer to the latter. + +In my case, I strongly value service independence and control of my own data. I put little trust in large corporate Internet companies, from privacy, security, and reliability perspectives, and would simply rather host my data myself. For this reason, I've spent the last 4 years building up my "homeproduction": a homelab used day-in day-out for my data needs, along with my family and friends. + +This is the first in a series of posts describing my lab as it exists today in April 2017. There will be three sections: Hardware, Storage, and Services. + +## From the bottom up: Power + +The homelab really begins with power - no electricity, no homelab! For optimal efficiency and to prevent overloading, my lab has a dedicated 20A 120V circuit run to it. The story of this circuit is a little funny: my box has a fixed number of fuses, and was full for as long as I could remember. But I never noticed one circuit was dedicated... to the doorbell! Goodbye fixed doorbell, hello homelab circuit! + +![Wall-mounted 20A outlet](/images/homelab/power-wall-plug.png) + +From the surface-mounted 20A plug, the single power input to the rack goes into an APC Smart-UPS 2200 RM XL, which provides 2200VA of protecting for approximately 10 minutes at 2/3 load. With my current contingent of gear this is the perfect size and has kept the system going through several small power outages. + +Power is distributed through the rack on two power bars, which provide A/B power feeds to dual-PSU gear. One of these distribution bars also connects to a second, smaller power bar for wallwarts. The goal with the dual distribution bars would be to eventually obtain a second UPS and provide truly redundant power (from the wall at least - it's a house!), but so far I haven't seen any need to (for the aforementioned reason!) + +![APC Smart-UPS](/images/homelab/power-ups-bars.png) + +All-told, the rack today uses at its peak about 1500W as reported by the UPS, averaging closer to 1300W. + +![Power usage graph, one week](/images/homelab/power-usage-graph.png) + +## The Rack + +The rack itself is an evolution from a few previous designs, including a large Lack-based setup and a smaller audio rack. In its current form, the rack is made primarily of 2x4s, pannelboard, and angle iron for rails, sitting atop six large castors to allow for easy movement. + + diff --git a/static/images/homelab/power-ups-bars.png b/static/images/homelab/power-ups-bars.png new file mode 100644 index 0000000..6274d75 Binary files /dev/null and b/static/images/homelab/power-ups-bars.png differ diff --git a/static/images/homelab/power-usage-graph.png b/static/images/homelab/power-usage-graph.png new file mode 100644 index 0000000..55b6be3 Binary files /dev/null and b/static/images/homelab/power-usage-graph.png differ diff --git a/static/images/homelab/power-wall-plug.png b/static/images/homelab/power-wall-plug.png new file mode 100644 index 0000000..d1948d0 Binary files /dev/null and b/static/images/homelab/power-wall-plug.png differ
