my hardware for the tape backup is
Server: PowerEdge R510 with one Emulex LPe12002-M8/2Port and Emulex LPe12002-e/2Port
Storage: Dell MD3600F
Library: Quantum Scalar i500 with one IBM Ultrium LTO5 tape drive
I have problems with the tape backup. It starts with 90 MB/s but after a short time the transferrate goes down to 2MB
. Our hardware vendor has no solution. So i plan to change the hardware from DELL to another one.
