Proxmox Disk Installation Requirements

[jsala]

"We are currently migrating all our clients from ESXi to Proxmox. I have been looking for installation recommendations for Proxmox regarding disks. We are currently using 16 GB USB sticks; is this considered bad practice? What is the minimum size Proxmox requires?"

Please note that this is for production installations.

Thank you in advance for your help

PVE makes heavy use of the boot disk. It is not recommended to use USB sticks of any size with PVE.
The better practice is to use enterprise grade SSD/NVMe. The best practices is to use 2 in a mirror config.

If you implement aggressive log rotation and are diligent in treating PVE as am appliance and not a general Linux server (i.e. dont store random files in your home directory) you should be ok with 32GB. Considering disk prices today, I'd go for 128GB.
