It depends on your company's backup strategy can you afford to lose even a
single backup session data. Many of us cannot (and of course there are
many who can).
Note also archives. They can be for fixed date and if lose them it might
be a problem (for example Financial Department will need Q3 data and not
Q3+Oct 1 data). TSM supports archive with deletion and in such case you
can lose *the only* copy.
Again, it depends. But think it thoroughly.

We then gave TSM the raw slices /dev/rdsk/c1t0d0s0 so he saw 6x36.
This
was the fastest by far. We were able to max the bandwidth (100M) for
over an hour (38G in one hour).
We lose the fault tolerance of mirrored disks, but we figure since
it is
only a staging area who cares? If a disk goes bad, we will lose the
data backed up to it, but we can always back it up again. We felt the
performance gains are well worth the redundancy hit. Though we have not
tested pulling a disk from the staging pool and seeing what happens.
