If you're running TSM 5.1.0 or greater, you can use the MOVE NODEDATA
command to move a particular client's data to a designated storage pool. If
you're running 4.2 or older, you're only going to be able to collocate all
new backups, not any of the existing data.

Incidentally, once collocation is in place, your restore speeds will be
somewhat faster if you regularly restore large numbers of files. However,
backups will be somewhat slower, because you will have to use tape volumes
dedicated to a particular OS's platforms.
