filesystems

I read the manual page of the "mount" command, at it reads as below:

All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree.

My questions are:

Where is this "big tree" located?
Suppose I have 2 disks, if I mount them onto some point in the "big tree", does linux place some "special marks" in the mount point to indicate that these 2 "mount directories" are indeed seperate disks?

Half of my ZFS filesystems are hidden in ZFS-fuse. Here's my story: So, I love ZFS.
