Hi: I was just curious if anyone has ever seen this before, its baffling everyone else I talk to and I'm about at the bang head on desk point. We have a backup server, it was running Windows Server 2003, and had an HP SCSI card inside that is basically a rebranded LSI Ultra 320. We were getting really fast backups, Backup Exec reported the average speed of 2GB per minute, and while someone said we could have even gone faster, that was plenty for us so I never bothered. Anyway, right before Christmas, I wiped the drive, installed Windows Server 2008R2 and installed the latest Backup Exec 2010. Everything works fine accept that the drive now backs up at about 100MB per minute. HP's Library and Tape Tools indicate the SCSI bandwidth has gone down to 5MBPS and should be at least 20MBPS. I don't know a lot about SCSI, but its almost like the card has fallen back to an older form of SCSI in some kind of backwards compatibility mode. The WS2008R2 drivers are up to date, and cabling wise nothing has changed from when it was working. I've gone to Symantec, Quantum (the vendor of the tape library) and HP and they all blame someone else in the chain. So I'm just curious if anyone knows what could cause something like this to happen? Thanks. Ryan
Hi, Have you checked to see if there is a firmware or driver update for this particular card? Best Regards, Billy L. Irwin Irwin Solutions 207 Strange Ct.

Good question. The version number of the latest firmware and that that shows up on the system management homepage are not even the same format. We're going to try an upgrade and see. Good thing I have a usb floppy laying around as the upgrade needs 2 floppy disks to work.
