I have test-Server with DataProtector 10.40 (as Cell-Manager with Disk-Agent and Media-Agent).
I have Tape Library HPE msl6480 (few LTO-7 drivers).
The tape library is connected via fiber channel to the DP-test server with a cell manager.
I tried to backup the entire hard drive to tape. The recording speed is just awful!
Only 3.5MBytes/s and 6.99MBytes/s to write files from this Server to the Tape LTO-7.
The HDD on Server has a SAS-Interface. There is no more Activity on the Server. The Processor is almost never used. FC-Card is HP NC533i DualPort 10Gb. Why such a low write Speed?
