Team; I recently replaced an HP G5 with a Dell R610. I am using a DELL LTO4 tape drive.
My HP server was running Backup Exec 2012 with my tape backup running at an average of 3500 to tape. WONDERFUL!
I moved the SAS 5/E card and the tape drive from the HP and installed them in the Dell R610 which is running Backup Exec 2012 (as I removed the HP) and now the performance is 1050 to tape. If I backup the server to DISK the performance is 3500
I checked the tape drive drivers and they are the Symantec drivers and unknown media changer. All the firmware appears up to date on the DELL as far as I can tell
How can I troubleshoot this issue?
