📜General recommendations

Sys requir. and recom. HW

System Requirements and recommended Hardware
Always useful, the official website recomendations.

Use Enterprise ssds

I can't say it enough:
Proxmox uses ZFS so make sure you use good SSDs.
Preferably business models.
Examples: Samsung PM893/897, Intel D3-S4520/4620, Micron 5300 PRO/MAX.

Dont use hw RAID card

Proxmox is not compatible with hardware proprietary RAID controllers. Use only motherboard-integrated controllers and/or LSI HBO card in IT Mode

📜Proxmox best practices

Update/Upgrade now!

Update your PVE now!

Time

Make sure the time is correct. This is very important when we look at the logs.
You can find it in PVE>System>Time

VLANs

Think Security by design, so think about creating VLANs from the GUI now and associate the respective VMs/LXCs to the target VLANs.

Start to think about a SMART mode to name the VMs/LXCs

For example, you can name VMs/LXCs (ID) with the last octet of the IP address. This will make identification easier in certain cases.

Set backup strategy

Personally I have a backup strategy both locally and to external storage (NAS, backup server and others). Local backups can be useful for example to restore a snapshot quickly, without being limited by the speed of your network ports (usually 1gbps)
