Is there a way to see where the osd is physically stored in a node?

Yes, issue this command in a shell window:
ceph osd tree
and you will see the list of all OSD in the cluster grouped per host.

lets just say if a osd fails. How would someone know which physical osd failed so he can replace it. Like he knows which OSD failed thanks to the ceph osd tree but how would he know that OSD.1 is the top left HDD

To get the node of failed disk quickly, you can click inside the red failed osds in the dashboard. if you registered the user to receive email alarms, it will also be there.
To identify where the disk is physically, you could keep track of the drive serial numbers locations, the serial should be printed on the drive, you could read the serial number of OSD/drive from the PetaSAN ui.
you can also install ledctl/ledmon package, it can blink drive leds on/off by device name if this will help.

i would recommend you install PetaSAN in a vm setup on your desktop to get a feel of it and use the getting started guide. Good luck.
