Changing self hosted hardware

[AartJansen]

I recently had an issue which looked like an SSD was failing, the server would stop accepting credentials for login (effectively locked up) with lots of i/o errors.
One of my troubleshooting steps was to move the SSD to a known good older generic PC.
While ubuntu booted ok in that box there was no network. it might have been an oddball LAN chipset, although it normally runs a manjaro install and that never had any issue detecting and using the LAN.
Another time I was using a cheap 2.5Gb PCIe LAN, which was nothing but problems when updates would "lose" it, I tried several fixes but it was easier and more reliable to revert to the onboard 1Gb

So my questions are

1. How do I determine ahead of time which LAN chipsets are going to work well on my cloudron should I need to change hardware? So I can have spare non-identical hardware as spares.
2. Is there a binding process to be aware of, for all the virtual eth that cloudron uses for Apps? I have them impression its very robust, and provided the underlying ubuntu loads up an ethernet interface all else will just work.
3. What if there are multiple ethernet adapters present ? Can they be bound together for higher thoughput, or redunancy ?

@AartJansen wrt hardware, as long as your server works with Ubuntu, it should all work with Cloudron. The filesystem has to be ext4/xfs .

Currently, there is no mechanism to bind apps to specific eth cards. There is also no mechanism to make specific apps use specific outbound IPs.
