Not necessarily. Just start multiple restore sessions. Do a DSMC RESTORE command for each drive. You may run into tape contention if files from different filespaces are on the same tape. You could also co-locate based on filespace to reduce the tape contention. How often do you do these kinds of large restores? Is it worth the management of mutliple node-names and include-excludes for each server based on how often you restore? If there are requirements for this type of speed on restore, maybe directing those servers to a separate storage pool that is co-located?
I'm not trying to pick apart your backup strategy, just trying to understand it. There may come a time where I have a client with these same needs and the information in this thread would come in handy.
