Proxmox in production questions

Do Proxmox have a CLI specifically or can do you use regular KVM for automation tasks?

By default, the enterprise repo is used that requires an subscription to get Proxmox updates but you can the no-subscription repo instead.
OK, so if you don't pay for support, you will not get any proxmox updates? Or at least not proven stable updates.

Correct, you won’t have access to there enterprise repo.

I should imagine/hope if there was a serious breach that needed an update, they would push this to the non enterprise repo as well.

I am using a promox server with the following raid-RAIDZ-3. A variation on RAID-5, triple parity. Requires at least 5 disks. It works awesome for my VMs. It protects me fully if one disk goes down.
Raid 5 does this natively, how is this some amazing feature?

This is ZFS RAIDZ3, probably the only implementation of RAID7. It protects not from just one disk failure, but from 3, at the cost of rather severe performance penalty. Not something one would put production loads on, even with all flash array. Probably better used for storing backups.

@marcinozga better used for nothing.

I have two ProxMox servers headed over your way tomorrow! I was getting them ready today. But we are doing EXT4 on hardware RAID on these.

Really hits the CPU hard. It was intended for giant storage situations like BackBlaze.

RAID 5 is single parity.
RAID 6 is double parity.
RAID 7 is triple parity.This is RAID 7.

You get the updates from Debian.

You get the updates from Debian.
I checked and Proxmox doesn't use the Debian kernel. They use the Ubuntu kernel and then add zfs on linux and other things to it.
So through Debian you'll get updates to userland. But the kernel, drivers and anything proxmox related has to come from the proxmox repositories.

Sorry, I could've swore this said protects from 1 drive failure....
