Usually with NMS or monitoring systems in big support companies, you have one machine outiside of everything(different power,switch and 3g modem usually) so that when anything or everything dies you get notifications etc. If you are maintaining...
here is how i do it in ex2200:

I had similar problem with megaraid_sas, the zfs 1 boot disks couldnt write to it if the machine load was high. Once i've shutdown the Vms on it, the kernel upgrade or proxmox-boot-tool would run okay. this was supermicro.
What is the use-case for SaunaFS in Proxmox, for image storage like CephFS or do you run VM's on it? Since you are using sata drives, did you run some fio tests or similar to compare the perf to ceph?
If you are using hardware raid, then you format it as lvm-thin by default(i usually do). Then you create Splunk on top of that. But why raid5 instead of raid10, much more IOPS you get from that.
