« Part 3: Sanding and finishing the parts. Part 4 of DIY 20u + Server rack. series no next part

As my regulars know, my forum time, and my vlogging is as real as it gets. I make mistakes, and I recover.

What is not shown in my video is that I had to take the spreaders front and back off, and cut 5/8” off, and redrill the holes, which I left natural because, well I wanted to be done with the project. I thought the 19” was hole center to hole center. I was wrong. It is outer edge of the mount ear to outer edge of mount ear. So now it fits!

I have the rails to install the servers installed, I have 3 desktop servers that I am going t flip sideways on these rails. Above that are the iSCSI switches, the 1u KVM mounts above that, and the top U will have a shelf to hold the SFF PC that is being used as a head node / eSATA storage controller, and eSATA RAID enclosure…

FOrgive the nasty carpet. I am ripping every single fiber of carpet out of this house slowly but surely.

I assume you could have purchased some kind of metal rack that would do this job. However, just like I would probably do, you picked a method that was undoubtedly cheaper, and was made for your equipment in particular. I don’t have anything that complex to house, although my office desk houses three computers underneath, and three screens on top (corporate U shaped thing, with the screens on the bottom of the U). I have switches that allow the screens to be run by individual computers, or they can all be run by the main computer.

My desk also houses the cable modem, the Wi-Fi router, and a switch. There are Cat-5 connections to various places in the house, including the dining room/kitchen that has three, and the rec room where my wife has her computer, and a surround audio system with a Cat-5 connection for streaming. The printer, scanner, fax machine also sits on that desk, as well as the main two line phone with 6 wireless connected phones throughout much of the house.

So, as you might guess, there is a lot of wiring underneath my desk, and did I mention a flightsim yoke and pedals, as well as a driving wheel? Wires run in some repurposed aluminum channel, and there are permanent work lights underneath it as well… (-:

The three keyboard trays I made from wood that slide in and out on drawer slides. The main one is built to a more robust standard to hold my flightsim yoke, or driving wheel…

...and some people just run a laptop or two on Wi-Fi, like my La Conner setup. Except, I run the computer there on Cat-5 since its Wi-Fi modem is not updateable anymore due to the age of the computer. Works good, though. There the electronics hub is in a closet in a central location. Along with a number of Cat-5 connections, Wi-Fi, a security system, and security cameras. So a pile of wires coming into that closet.

Amazing how electronics and computers are taking over our lives…

Later…

Well, remember what I do for a living. Yes I could have a metal rack, but I needed a custom size. None of my equipment aside from the switches are really rack mountable , so I improvised.

I have a total of 5 ethernet switches, 2 16 port in this rack for an iSCSI SAN for the computers in the rack, a 24 port that is wired through a patch panel and then distributes category 6 cable through the house. Each bedroom gets 2, the master and living rooms get a LOT more for consoles etc… the garage and kitchen get 2 etc…. The cable modem, and router are going to be stashed above the kitchen cabinets to centralize the WiFi signal as the kitchen is pretty much the middle of the house.

Because of what I do for a living, and where I work, budget for keeping up on tech is almost non existent, so I have to build my own training lab network to stay on top of what I can.

The computers in this rack will be 3 @ oVirt compute nodes, based on 8 core AMD based clone boxes, one oVirt head node / iSCSI / eSATA controller. This is basically a private virtualization infrastructure. Not quite cloud, but the biggest pieces are there. I have Windows 10 and SErver 2016 VMs as well as CentOS 7 and Ubuntu Linux VMs running in here. All of this will be attached to an 8 port KVM switch which will be run to a 32” monitor, keyboard, and nice mouse in a computer armoire just outside of this closet There will be an additional KVM cable run to that to connect my laptop to this to act as a docking station.

Hard to explain, but I have it set up such as when I move, I will be able to tuck the cables behind the wall into a structured wiring cabinet and call it a smart home feature. I will have to leave one of the 16 port switches. The 24 is too big…

I have at present 6TB or 8TB RAID 5 storage so not huge on space, but not tiny. Most of my non virtualized stuff is off on external HDDs anyway…

I think I have said before, that I nibble around the edges of the computer/tech world, but I am still just a savvy consumer. I think most of the heavy stuff is for your music and recording, right? My needs for storage are not extremely high, since I don’t take a lot of pictures and I don’t collect music, either. A little of both. My flightsim hobby puts the most demands on my computer, and takes up a lot of space on the drives. I recently upgraded my C: drive to a terabyte Samsung Evo SSD. The previous one was just 256 gig, and was a bottleneck.

My side computers are both HP desktops purchased for less than $400. I already had the monitors. Those computers mostly support my flightsim hobby. They have moving maps that actively track where I am flying in real time. The flightsim program has multiple methods of communicating over the LAN, so add on programs that use that feature are commonplace. But those computers really don’t do much in the way of processing data, and the basic video is adequate as well. I used to use outmoded computers in those positions, but my current main computer just keeps chugging on, while the old ones died. Hence I just bought cheap new computers for the side computers.

You are in the right business, because the tech world will just keep expanding in an explosive manner. I assume most of your expenditures could be considered business expenses. At one point, a lot of my computer equipment was partly business oriented. In the latter years of my practice, early in the morning, I would review patient progress, and manage medical records at both hospitals from home at the computer. Then I would review my clinic online schedule and patient records for the day, since we went to EMR a few years before I retired. Then when I made rounds at the hospitals and saw patients in the clinic I was much better informed and much more efficient, a benefit to me and the patients.

My main computer is about to be 8 years old, but has the 6 core Extreme processor from Intel, 24 gig of memory, a couple of video cards, etc. Falcon Northwest built it, and it refuses to die.

Video or photo the setup when you are done installing everything, should be interesting…

On a related tech note. I picked up and installed an item that is related to this rack. An Obihai Obi202 2 line VoIP adapter.

Translated to english right?

I picked up a piece of hardware that allows me to connect a regular analog telephone, and / or fax machine to my internet service, that allows me to have a dedicated telephone line, and a dedicated fax line for my home / home office…

Most of the videos out there don’t tell you anything beyond setting up the first line. I went into detail on configuring it for the 2 lines. There is some prep work that needs to happen on the Google Voice accounts but those are very well documented elsewhere…

Anyway, here’s the vid…

My next videos are going to be either about dust collection, or more work on the bathroom wainscotting. or refinishing the cheap wooden medicine cabinets… Choices, choices…

Out of curiosity, is a Google account like a Microsoft account, meaning, it doesn’t cost you anything just for the account? Do you incur any charges with either the account or Google Voice?

I don’t have any need for another phone here, but it might be nice to have one at our vacation home, if the hardware is the only expense…

Currently, we just use our iPhones when we are in La Conner…
