Dell r720xd 2u 72tb raid5 storage help

[rayhan17c]

Hi guys, I have installed Proxmox on my dell 720xd and used an ssd drive for installation. Now I have 12*6tb drive on my server and already setup hardware raid5 now how do I use the HDD on Proxmox? I want to create a KVM VM which will be used to host big files such as videos. I tried making the HDD ext4 and then mounting but this way I can't assign more than 16tb on guest os. What would be a good solution in my case considering the files that I am going to host on the guest VM will be accessed using 10g Lan. So the read/write speed is very important here.
Thank you

Attached. vgs and pvs showing 40tb because I just now configured the 60tb raid as lvm and assigned a 20tb hdd on guest VM. is it good enough to use lvm in my case? what would be the performance? Or should I look for an alternative option? what are the best practices in this type of scenario? Thank you so much for your help.

You have 60TB second drive (/dev/sdb), you can mount that drive as local storage (in /etc/fstab), make sure to create a file system using command mkfs.ext4 /dev/sdb
or you can configure LVM on top of second storage
and then configure /etc/pve/storage.cfg to use the storage
