Upgraded server RAM, what changes do I need to make

[mew1033]

I have a pretty simple home server Proxmox installation. I'm mostly just trying it out and learning. I had 4GB of RAM in the server, and I just added 16 more. Do I need to make any changes on the server side to optimize Proxmox for this new amount of RAM? I'm running ZFS (not on boot drive).

Thanks!

Hey!

You don't need to do anything. The default settings should work well. What i suggest doing in your particular case is:

1. make sure you limit the amount of ARC cache. The ZFS can quickly fill a huge chunk of RAM and even though it is limited to 50% by default, it can still be way too much for your setup. 4GB of ARC should suffice. Link: https://pve.proxmox.com/wiki/ZFS_on_Linux#_limit_zfs_memory_usage
2. you can expand RAM per VMs/CTs if needed.

Other than these, i see no need in other adjustments.
