Until recently, and for well over the past decade, my wife and I have been nomads. This has meant that for many of those years, my home office basically comprised of a few laptops and screens. These days, we are more settled; my wife has completed her studies, now works full time, and my full-time job remains remote, via a home office supporting Linux servers and hosting them.
Last week, after a short trip to Antigua, I had a brief meeting with a tech friend of mine, Yves Ephraim. We sat in his home office, where he open hardware lab kr me a bit about his current projects, as well as his dabbling with IPv6web hosting, mail, BGP4 open hardware lab kr, among other things.
Most of which he does via his very capable home lab. My current Home lab in a 12u rack as of May open hardware lab kr Think of a home lab as a place where you can fail in the privacy of your open hardware lab kr home. As Thomas A. But seriously, I would like to fail a lot more, and a home lab will create endless opportunities for me to fail.
Of course, all the while seeking success, but you got that already. In general, a lab is a place where you can safely open hardware lab kr experiments.
Most of you reading this article are techies and sysadmins. As you know, trying out new things on production equipment never ends well. This risk is the reason why we build ourselves a sandbox environment to dabble, open hardware lab kr, and fail in, all from the comfort of our own homes. To date, I host my test labs on servers in North America and Europe.
I will also be using my home lab for remote backups, network monitoring and alerting of remote serversand wired UAP APs, among other things. As I told Yves, our chat had me revisiting the idea. In light of this fact, I wanted to share this journey with you, starting with the hardware selection process for my home lab.
Well, sort of. Where do we begin? Location, Location, Location. Location is critical for several reasons. The choice between the home office, living room, closet, attic, basement, or garage depends on a range of important variables. These include room temperature and ventilation, workable space around your equipment, ease and distance of network cable runs, foot traffic, hour ease of access, power, noise levels from your home lab, and more.
Choose wisely:. I have laptops, a desktop, a server, and other devices in my office, so that this location will require shorter cable runs. Keep in mind your floor plan and how you will accomplish the cable runs. Think about these things before, not after. In other words, map everything out, make notes and create lists. Next, we need to decide how we will store the equipment modems, routers, switches, servers, patch panels, UPS systems, power strips, cooling fans, etc.
Network cabinets and racks are often confused with S erver cabinets and racks. R outersswitches, patch panels, and the like are usually much shallower than servers. Also, networking devices often produce open hardware lab kr heat open hardware lab kr servers.
You will open hardware lab kr some network cabinets will have glass doors that may not leave enough ventilation for servers. After deciding the depth and ventilation requirements for Open Hardware Lab Kit your home lab, there are a couple of other things to consider. To help you decide whether to use a cabinet or rack, consider the following:. Or not. However, most of the above advice applies even if you plan to set up your home lab in your existing living room cabineton a bookshelfopen hardware lab kr your deskor in a cardboard box.
No, seriously…. Image : Fancy cardboard box cabinet. As a reminder, you can get most of the equipment listed below via Craigslist, Universities, and other local second-hand options in some countries. If links to manufacturer pages become broken over time, please let me know, as it always seems to happen.
Before we delve a bit deeper into my open hardware lab kr lab recommendations, if you are a beginner to switching and routing, then a lot of the hardware below may seem to be a bit of an overkill. Yup, that one, the mini heater in your living room. Buying your own could make some financial sense. As well open hardware lab kr giving better performance, reliability, and security.
Bet you were already sold with the financial bit eh? But it gets better; most of these modems provided by ISPs are usually of poor quality, used, and lack features. This means you are at the mercy of your ISP to push new patched firmware. If you have a great ISP and this does not apply to you, stick with your modem. The only reason to replace it in such circumstances will be to have access open hardware lab kr additional network features and create a home lab where you can test away!
When deciding placement, I would suggest toward the top or leave space below and above. That said, I love this modem! A typical full-size rack is 42U high. Racks and cabinets are then listed as 1U, 2U, 3U, 4U, and so on. Update: This is a very solid wall mount rack. I can confirm that what you see is what you get. No issues to report.
At home, we have a backup generator that runs on propane. It can run for up to a week, which is open hardware lab kr in the tropics. Other than hurricane season, power cuts are extremely rare here. So far, forwe have had one outage that was due to a lightning strike on a nearby electrical post.
It takes a minute or so to failover to the backup generator. Long enough open hardware lab kr fail-over to the backup gen or to shut down all the equipment cleanly. Ultimately, you will have to decide whether you even require an uninterruptible power supply at home. From experience, UPS batteries are almost always a disappointment, and this open hardware lab kr largely because of the cost vs. If you really need to have a UPS, you could spend thousands just to have a long enough runtime.
My advice, get a UPS open hardware lab kr provides just enough runtime for everything to shutdown cleanly and only use the UPS for the most essential and efficient devices in your home lab. Update: Surprisingly, the battery performance of this UPS so far is above my expectation. As mentioned later in this article, pay attention to your power consumption.
The APs for example, max power consumption is just 6. Lastly, for this setup, it will look more professional if placed on a ventilated 1U rack shelf:. Update: Very sturdy, great for keeping equipment cool and cable management thanks to the vents and slots. Right above the UPS, I will be mounting the following:. Update: This is a very convenient piece of hardware. Maintaining an optimal temperature for open hardware lab kr equipment prevents overheating, ensures consistent performance, and extends their lifespan.
The plan is to mount an intake fan at the bottom rack unit position remember hot air rises. Update: At the lowest fan speed, this cools rack temps by about 2 to 3 degrees Fahrenheit.
Sorry TP, nothing personal you are just 3rd, but not open hardware lab kr, is that better? I plan to circle back to this section and post another article with my new network setup. The following were my selections, followed by the runner ups.
Of course, this means that you will still have to research the recommendations on your own, as not all of my picks may fit your requirements. Update : Just open hardware lab kr I needed. The router runs modified Debian. How cool! In hindsight, I should have gone with the 24 port patch panel. Instead, I went with this 16 port patch panel because, well, I liked how centered and less-busy it looked.
I know. But look at that thing! Thankfully, you do get what you pay for, and kudos to them! Yeah, I also like my coffee black. If you want smoother network open hardware lab kr, then, by all means, go for at least CAT6a.
However, make sure you go with a shielded patch panel. Update: High quality! Easy to punch down. All my patch connections worked on the first try. NAS storage, VMs, web servers, backup servers, mail servers, ad blockers, and all the rest. For home labs, these are often best purchased used from Craigslist or eBay.
