Hi Allan!
You're probably using compression at the client side.
The capacity for MP tapes is 5000 Mb, uncompressed. IBM assumes a 3:1
hardware compression ration which is fairly accurate when you store
uncompressed data on the tape. However, if you store data on the tapes
which was already compressed by the client,  the hardware cannot make it
much smaller, so you will see the real tape capacity: 5000 Mb.
Kindest regards,
Eric van Loon
