Merry Christmas to All and to all a Happy Holidays!
For us, we’re having 2 Cornish Game Hens with stuffing (currently thawing out for prep tomorrow as we get Christmas nearly last; only Hawaii is later, by 2 hours… then some spots in the Pacific…
I’ve taken the opportunity to re-do my lab / desk layout and FINALLY have the set up I’d originally envisioned a few years back.
I have the Ordoid C1 (it was supposed to be the C2 but it died…) driving the TV Set as “general monitoring and videos” station. So I can put up “htop” panels for every other system and have a full HD board of condition displays. As it is also able to drive video (only up to about 480p but that’s OK for Youtube general info and music) and makes nice stereo sound – so now I have my Media Center at the desktop too (the good one is in the bedroom ;-)
My DVI Adapter monitor is for “Work Du Jour” and is now completely free of monitoring other systems ;-) So I can bounce it up and down and not need to restore a bunch of long duration sessions or htop monitors. It is set up to use the System Du Jour (currently the Ordoid XU4 as it is just dandy for enteral Blog Stuff (minus sound as the DVI quashes it…)
The Dogbone Stack of Pi B+ (the v6 original single core 700 MHz) and a Pi M2 (original quad core v7 900 MHz) are in the bottom two slots both doing DNS / Squid Proxy and connected to UPS power and the “TV & DNS Network” aka the Telco Router. I’ve got one more Pi M2 in the stack that’s set up for distcc and general cluster playing (as is the other one) but at present powered down. Then the Odroid C1, so no more “junk on the desktop” to drive the TV as monitor. Finally, wire tied to the top is one of the Orange Pi One boards connected as my NFS File Server (with the 8 TB disk behind / under the TV – all out of the way at the back edge of the desk.
So most of the time at least 4 of the 5 things in the dogbone stack are powered on and working. The other one when I want to do distributed compilation of v7 arm code. Behind my DMI Monitor is the 2 x power strips ( File Server on a dedicated one so I can switch it all off together when not in use. Why have files on line and exposed if you are not actively using them?) and the Ethernet Switch for the private side LAN. It has an uplink to the Netgear that isolates from the TV / House / DMZ network.
On my desktop are two Ethernet ends to the two major networks so I can boot a system into either destination as desires happen. The front 1/2 of my desk is substanially clear other then KB & Mouse (mousepad and mice…)
Notice that missing in that list is any mention of my 2 x USB Powered Hubs!
The Orange Pi One is using a powered USB disk, so doesn’t need any extra power, and running headless has no need for KB or Mouse connections. The move to one big disk eliminated the need for the Hub.
The Ordroid XU4 has a big fat barrel connector to power the local 2 GB hard disk, and 2 ports for KB & Mouse. I’ll need to attache the hub if I want to play with multiple disks, but otherwise, it’s a “done deal” As primarily just a place for “daily stuff”, I think I’ll not need to attach a hub very often. Mostly I expect the hub will be attached to any “variety system of the day” when I swap the monitor, kb, & mouse onto that board for “whatever” project – like finishing the Pocket PiHole on a R.Pi M3.
Basically, with the “Monitoring Station” all set up and happy with a browser, the “Workstation” can be shut down any time for “play with something else” and minimal plugging of things – just move KB / Mouse / Monitor over as needed. (For things run as headless servers I can just power them up on a network spigot and use the Workstation as KB/Mouse/Display via remote connections.)
You may have noticed that other than the one ancient v6 system, this is all v7 32 bit stuff. I’m going to be assembling my v8 64 bit systems into their own cluster (though maybe not a dog bone case, not sure yet as they are all different sizes ;-) so I can do distcc on v8 codes and run very fast math problems (as the v8 codes know to use the GPU for math…). This will have some minor issues in that they are not all the same kind of system so we’ll see what surfaces as I assemble the cluster and make it go. The v7 32 bit stuff is fine for general desktop and dedicated server stuff and frees up the “hotter” 64 bit boards for heftier compute stuff. I expect that over a year or so the RockPro64 will become my major desktop replacing the XU4 (that becomes just a v7 cluster node then), but the software needs some maturation first.
With that, I’m on to sorting out the couple of dozen “System Images” I’ve accumulated over the years. Some times I’d just “move on” to a new chip / SBC / system as a general reset on “anything that’s accumulated”; and now there’s a few that are in the “not going to use that again” pile that really need a final “harvest anything you saved there and want” prior to a scrub.
Yes, I’m doing “Christmas Holiday Lab Cleaning” ;-0
Hey, after a few decades of working EVERY Christmas ’cause that’s when we could shut down the computer room (as all the staff were on holiday…) it’s a habit now ;-)
Well, time for tea and maybe a spot of lunch!
