How long are the SCSI Cables, are you sure the termination is ok. Might be a bad cable. Differential SCSI is really picky.

We're using this library with a IBM P-Series 610 with one FC adapter. The problem is that the performance of the 2 SCSI drives attached to the SDG is very poor. The FC drive has a good performance and can reach speeds up to 27MB/s, but the SDG will only reach about 4-5MB/s, which shoulod mean 2-2.5MB/s per drive. The 3584 drives(both SCSI and FC) are upgraded to the last level of firmware(was done a week ago), and the library is at level 2250. Is this a know problem with the San Data Gateway? We should at least be able to reach about 10-15MB/s thought the SAN Data Gateway. Appreciates any help I can get. Best Regards Daniel Sparrman
