Direct attach is supported for STK 97xx libraries.  Direct attach
appears to
have a few other differences than just non-support of multiple ADSM
servers.
Direct attach will not support mixed media, also loading and labeling
volumes
with direct attach is a bit more painful, IMHO.  The licensing structure
is
different as well.  ACSLS-attached 97XXs fall under Module 3 support;
direct-attached 97XXs fall under Module 4 support.
