The space currently uses a lot of old, power hungry hardware and could be optimised by the addition of a small amount of money to refresh the infrastructure. This page stands to collect the ideas on how and what to do with performing this task.
Todo
Auto poweroff when space is closed
Lights
Sonoffs for TL lights Zaal 1, zaal 2, toilets, gamerhok, aanrecht.
Heating
Pipe isolation.
Other
Shutdown script for Arcade and Studio.
Add body movement sensors for various Jarvis switches.
Solar power
Done or almost done
OpenTherm Gateway with automations on Jarvis.
A whole bunch of switches for Jarvis.
Shutdown script for zaal 2 computer.
Fans for radiators to move heat around.
Monitoring on Grafana with Power meter.
Proxmox Servers
These systems take a lot of power (3 pieces of about 200-400W a piece) (confusion , precious , anotheroneikeepforgetting )
Usage
We run a copious amount of virtual machines on our Proxmox cluster
Replacement
Slab has been replaced by SlabPi
All TL lights have been replaced with LED.
Wasteful ancient coffee machine to be replaced with thermos coffee machine soon.
Not sure if this is totally viable, but :
This quadcore CPU has full VT extensions, but is just 10W TDP! For 99% of our VMs, this is probably already a sufficient host. Motherboard has a max of 16GB (in 2x SODIMM DDR3 1866mhz)
Questions
- How is the reallife performance?
Netapp
The Netapp storage has been identified as a power consuming piece of hardware. It is also FAILING STEADILY so this is important to upgrade!
Usage
This machine is primarily used for NFS mounts across the infrastructure.
Replacement
- The0 has a 3u case/machine
with 12 disk hardware RAID controller(controller has broken ports) with brackets but without disks in it that might make a good replacement. - We could construct a JBOD and do software RAID - using the an ASROCK c2750d4i is a good starting point but it is kind of expensive.
- Maybe 3 old atom boxen with each 4 disks and something like ceph might also work?
- Or buy a new motherboard and use zaryas 4 port Areca controller
Printer-desktop
Could be replaced with something like Octopi
Update; this is mostly done atm, thanks to Pokon
Questions
- Are we going to keep the touch screen?
- How much power does the touch screen take? And in stand-by?
Migrating VMs
As many VMs currently running at the space infrastructure do not really need to be hosted at the space, we could migrate many of them away.
Zarya offered to host them in his broomclosetserver (actually not at his home, but at a soccerclub) , we could also ask site4u/bit if we could get some Units 19" space in Ede.
We started making a list of the currently running VMs and noting if they are needed and for what ;
