Volume Mounts vs Directory Junction

Hi there, I am bulding a 2008 R8 Fiel server as a VMware VM. the aggregate data being managed by this FS is failry large - about 5.5TB. It is a mix of Video, Photo, Music and other file data.
I need to break up the volumes in order to keep the VMDKs at a manageable size (< 1TB, so the DSs can stay at 4MB blocksize), yet i need to presetn the data - ideally - as a single share to the outside world - at least to the users, backup is a different story. All DSs will be iSCSI conected to an openfiler box.
I was wondering if there are opinions out there how to solve this best - with mounted volumes or directory junction points, or some other way, and what the pros and cons are......

Thanks for any input !

I suggest breaking it up into separate drives and assign them each a different drive letter. Use a domain based DFS namespace to tie everything together.  This has the advantages of allowing you to move things around on the server, or even to different servers without changing the UNC path to the files. Is should also make it easier to transition to cloud storage.

If you did mount points you tie everything to that server name. It can also make backups a little bit harder.  I would even choose a standalone DFS namespace on the file server over mount points, but a standalone DFS namespace still ties you to that server name.

Have you considered putting this into the cloud? Thare are cloud gateways that have a local appliance that cache files locally for speedy access, but sut everything in the cloud for long term storage and inactive files.

Great points - thanks kevinhsieh. I thought DFS could only tie in shares from other servers, but I guess you can just map the UNC path to a local drive ? Does that work. If that is the case I agree that domain DFS would be the way.....
DFS just ties together UNC paths. In this case the DFS root would be on domain controllers, and everything would point to different shares on your single server, though you can also tie together your other file servers as well.
