Hi, don't know if this belongs to -scsi or -hardware or elswhere... I'm running 2.2-BETA on a P166 with two Adaptec 2940. I plan to use amanda to do backups on a DEC DLT which is connected to one of the two 2940s. Since a lot of files to be backed up come via a 10 MBps network, I want to use a holding disk where the data is being collcted first and then written to the DLT (which is significantly faster than the network). To optimize performance, I would like to know if I should connect the holding disk to the same 2940 as the DLT is attached to or to the other one. My thoughts are, that if I had both devices on different controllers, the throughput could be faster since the data is read from one controller and pushed directly to the other one. Maybe someone has already experience with this, or some of the SCSI experts can give me a small hint... Thanks in advance, Andre
