Is your backup server running on Linux or Windows?Are you using the latest tape drivers from IBM?

Check to see if the drives are logged in as F or FL. I believe that you should with the proper driver be able to get them to log in as F-ports which would be preferred (less overhead).

Try using tar or dd to write data to the tape and see how it performs.

Also, what about compression? Are you sending compressed data to the drives that the drives are then trying to compress?

If anyone knows how to disable compression on IBM 3583/3582 LTO-2 drives that would be great!!

Re: Tape Optimization?

When you say "Arkeia supports the drive directly", does that mean you are not using IBM's tape driver? If not, I would try that. I might also let you disable compression on the drives.
