Proxmox and Hardware RAID, which storage type must use? I have been building a "Production environment" for apps 24x7, 3 IBM server (x3650 m3) (for now, but we have 8 x3650 m4), LSI raid card for RAID 5 on each one (for fault tolerance on each node); On top, Proxmox 6.3 with cluster and HA function on VMs and containers, and fencing to move machines on trouble. Now ZFS apparently it's not an option for storage because i use hardware raid, which can be the better config?

In forums only home labs available.

Thanks for your advice, we want to work with proxmox and i sure we can move all our machines from oracle VM manager
 
If you want to use ZFS you can try to set the raid-controller into jbod mode. A lot of LSI cards do support this.
JBOD mode disables the raid engine completely.

Otherwise obviously you will need to stick to LVM.

I was able to flash my LSI raid card to IT-mode. In that case the LSI raid card works without raid and is just a dumb HBA fine for using with ZFS.
Not sure how that voids warranty if your raid cards are rebranded. I just used the official LSI firmware tools to flash another official LSI IT-mode firmware.

Looks plausible.
I know different screens but in the end it varies by vendor and model.
Once configured you should just see the disks as they are (Seagate, Hitachi, Whatever) instead of a "megaraid LSI SAS device"
