I'm installing proxmox ve 7.4 on dell r750xs server with two 960gb ssd disks. On the internet they talk about doing a raid 1 on the controller. What do you recommend to do?
 
Depends on what you want to do or will do in the future. Are you having a raid-controller or a hba? If raid-controller then you can use raid1 and go with ext4 and make lvm-thin pool in proxmox ui -> there you can put your vms.

if you have a hba then you might go for zfs, this is not allowed on raid-controller cards, only on hba or onboard-cabling. if you might add another server in the future, you could setup some ha-kinda like setup with zfs-async-replication between two hosts (+ a third quorum). As this is only possible with zfs, you should think about this even when only starting with a single host.
 
Thanks for your answer,
I'll explain what I have to do, I have a r750xs server with two 960gb ssd disks, and a server with proxmox backup server in which to backup virtual machines. In the worker node I did a hardware raid 1 with the H755 PERC controller. When I installed proxmox I formatted the file systems with xfs . In node I made a virtual machine with centos always with xfs file system. At this point the DELL server for the backup system I always do a raid 1 and format in xfs ?
 
I guess XFS is also ok :) What disks are you having in the pbs? Its always good to separate OS and data, so separate disks for the backup-store would be cool. I never tried using the boot disks of the pbs to also use them as a datastore. Might work
 
Hi, for pbs I'm using a dell PowerEdge R350 server with two 1.92TB SSD SATA Read Intensive 6Gbps 512e 2.5in drives. I would like to deactivate the controller and in this case format in RAID 1 zfs. Do you recommend doing it this way?
