Ask Slashdot: Tiny PCs To Drive Dozens of NOC Monitors?

mushero writes: We are building out a new NOC with dozens of LCD monitors and need ideas for what PCs to use to drive all those monitors. What is small and easy to stack, rack, power, manage, replace, etc.?

The room is 8m x 8m. It has a central 3x3 LCD array, as well as mixed-size and -orientation LCD monitors on the front and side walls (plus scrolling LEDs, custom desks, team tables, etc) — it's designed as a small version of the famous AT&T Ops Center. We are an MSP and this is a tour showcase center, so more is better — most have real functions for our monitor teams, DBAs, SoC, alert teams, and so on, 7x24. We'll post pics when it's done.

But what's the best way to drive all this visual stuff? The simplest approach for basic/tiny PCs is to use 35-50 of these — how do we do that effectively? Almost all visuals are browser-only, so any PC can run them (a couple will use Apple TV or Cable feeds for news). The walls are modular and 50cm thick, and we'll have a 19" rack or two, so we have room, and all professional wiring/help as needed.

Raspberry Pis are powerful enough for this, but painful to mount and wire. Chromeboxes are great and the leading candidate, as the ASUS units can drive two monitors. The Intel NUC can also do this — those and the Chromeboxes are easily stackable. My dream would be a quad-HDMI device in Chromebox form factor. Or are there special high-density PCs for this with 4-8-16 HDMI outputs?

Each unit will be hard-wired to its monitor, and via ip-KVM (need recommendations on that, too, 32+ port) for controls. Any other ideas for a cool NOC are also appreciated, as we have money and motivation to do anything that helps the team and the tours.

      You say Raspberry pis are "a pain to mount and wire." Have you really thought about this?

      1 - Power (wire one)
      2 - HDMI (wire two)
      3 - wifi plugin. Can be set for static IP. Even a minimal router will allow you up to 50 clients on one WiFi subnet. Apple airport, for instance. And you can use more than one, so you can go up to 250 clients if you really need to. No wires. Unless we're talking about a really huge amount of bandwidth, wifi should do it. If not, ethernet cable, which would be wire three. Same issue with any client, though, so...

      My first question is, how are you going to get simpler than that? 2 or 3 connections. Seems like a doddle, frankly.

      So as to mounting:

      Is there some reason you can't use double sticky tape and just slap the thing on the back of the monitor? Or, if not that, which *is* a little hacky, use one of the ultra-inexpensive cases and put at the foot of the monitor like any other PC, only smaller, using less power, less obtrusive, etc?

      As to configuration, you can prepare the OS + software for these anywhere, walk up to the PI in question, insert the card, power it up, and you're done.

      None of these will need keyboards; any management you want can be done by SSH. Though why you'd have to manage an information repeater I don't know.

      As to reliability, it's pretty good, and hell, if one goes down, you unplug it, plug in a new one, and go on about your day.

      I really don't see the problem. Why would you do this particular task any *other* way?

  2. NVS by Anonymous Coward · · Score: 4, Interesting

    Take a look at the nVidia NVS line of GPUs, they're designed for digital signage but would probably work for you - the new ones support up to 32 displays driven from a single machine (4 cards).

    Asus and Intel are making these types of devices. There are probably other companies making them by now as well.

  4. Go for servers by v13235 · · Score: 4, Interesting

    Having done this twice in the past 4 years, my suggestion is to use rack mounted x86 PCs/servers with dual graphics cards. With ATI cards you can go to 8 or 16 monitors per server and as long as you keep a ratio of 1 screen / cpu, you should be fine (capacity wise). Using PCs (a) will allow for easy maintenance and (b) will be easy for others to work on them. PCs are also much easier to upgrade (hardware wise) as they keep the manual effort needed to a minimum. We've done this with PCs and PIs. PIs are a fun project and so far they work well, but you *will* be swearing in the process as you will have to figure out many things, including power, cabling, mounting, etc.

  5. A small PC, you say? by Anaerin · · Score: 3, Interesting

    How about something smaller than Intel's NUC, more powerful, fanless and reasonably cheap. Something like the fitlet for example. And VESA Mountable too.
