I've got three answers from people using ADSM with DLT4000 drives in
ATL libraries, two with 4/52 and one with 6/176 (none with 2/52). All =

three are pleased and has no problems with it. I've got no answers =

from people having problems with it.

I hope they will. And while doing so, add support for DLT7000 drives
as well, since a 2/28 with DLT7000 drives has about the same capacity =

(and doubled transfer rate) as a 2/52 with DLT4000, the 2/28 with =

device module 2 and 28 DLT-IV cartridges and the 2/52 with device =

module 3 and 52 DLT-IV cartridges.

Anyone tried DLT7000 with ADSM yet? =
