Yes.
You're on the right idea, you need multple storage units defined for each
media server. Each storage unit has a different media type.
The choice of client to drive is done by assigning the LTO-2 STU to the
policy that services your slow clients and the LTO-3 STU to the policy that
services your fast clients (in other words, break your clients into multiple
policies).

Subject: [Veritas-bu] multiple tape format in one library??????
Is anyone using multiple tape/tape drive formats in one library with a
single media server?
for example:
one server, one library
some LTO2 drives, some LTO3 drives.
how do you manage it? can't (from what I can tell) assign each type of drive
to a different storage unit (without a second media server).
Do you have both types of tapes, and let NBU assign jobs and tapes to drives
as it pleases?
I want to avoid my LTO2 tapes being loaded into LTO3 drives and being
written so that they can no longer be used in an LTO2 drive.
Also, I'd like to send slower (100mb/s) clients to LTO2 drives, and GigE
clients to LTO3, etc.
best way I can see to do that is to add another library for the LTO3 drives,
so that there's a separate storage units with just those drives, OR add a
second media server, and configure zones to allow each media server to only
see one type of drive.
