Petabytes and hierarchical storage management

[Christian Iseli]

Hi folks,

Anybody here aware of open source tools to have a HSM solution in
Fedora ?

What I'm basically after is something that
 - mounts and behaves like a normal filesystem
 - can manage petabytes
 - automatically migrates files to tapes (or other fancy low cost per
megabytes storage device), based on some policy when they are unused
for some period of time, and loads them back the next time a process
attempts to open those files
 - can be exported through NFS and samba

Cheers,
					Christian
