[PVE-User] Disk layout question

Hello all,
We have historically purchased servers with 6 SAS drives, set them up in 
a 3 x RAID1 configuration, and then placed LVM on top of the entire 6 
drives.  This has worked out well so far as it allows us to maximize our 
drive space.

However I need to build a few new Proxmox servers with I/O performance 
specificity in mind.  I started to think that for these servers I would 
still create the 3 X RAID1 configuration, however I would not use LVM 
across all 6 drives, I would instead just create 3 separate LVM 
partitions, so I can have a little more control over VM's use which drives.

One downside to this type of configuration is it might limit the maximum 
size of the VM's we could deploy here (however I don't think this will 
be an huge issue for us really).

I was wondering if anyone else has used this type of setup, and if there 
are any other things I should be aware of,  if I am going to setup the 
drives on a Proxmox server in this fashion.

Thanks in advance,
