These aren't DLT, they are LTO (Linear Tape Open).  A new open standard 
developed by IBM, HP, and Seagate.  I don't think the medium is 
compatible.

We just got one (i'm not sure if it is a 215 or a 230 since it came 
packaged in a changer).   In our initial tests we are getting about 5MB 
(1/3 the advertised rate) writing to, and a dismal 200KB reading from, 
the drive on OpenBSD 2.8.  How common is it to have such a difference 
between read and write speeds?  We're still looking into this...
