I've not used a 6000, but I remember the term from older units.  I
believe it is supposed to improve performance by directly acknowledging
tape writes into a buffer on the bridge and then pushing them to the
tape later.

If true, it could also lose data if it were to crash after it had
acknowleged data from the backup server, but before it sent it to the
tape.  That's something for you to figure out if it's worth it.
