Thanks a lot, Paul, for that feedback. Seems that you will be the first
to really test it, my box will arrive next week, I assume. This will be
an installation from scratch so no SAS-related stuff there already.

I wonder if it makes sense to attach the disks to that adapter as well?
This box will do amanda backups ... so there will be the amanda holding
disk and it is important to have maximum speed between that holding area
and the tape drive. I plan RAID1 on 2x2TB disks at least or maybe even
RAID0 (it's a rather temporary storage area so the redundancy isn't that
important). Testing will show!

Greets, Stefan
