Drobo NAS mounting

I have Home Assistant running on a Dell Server connected to my home network via LAN. I also have a Drobo NAS connected to the same LAN.
I use Proxmox on my server, and am running Home Assistant on a virtual machine.

I created a directory on my Drobo NAS for Home assistant and my intent is to mount the directory to my Home Assistant. I am able to access the directory from my PC, so that all is working. But how can I get to associating it with Home Assistant so I can save files to it. Right now, I am only able to save files on the same drive where HA is installed, under the shared directory.

Any pointers?
