We have a 4/260 with SCSI. This is essentally a 3/160 or 3/260 with a SPARC processor board. It uses a SCSI-3 interface board which connects to a Emulex SCSI->EDSI adaptor which connects to a single EDSI disk, currently a 327MB Micropolis 5 1/4" (380MB 1558). There seems to be an extra connectors in the pedestal unit, where the single drive currently resides. There is a wide connector daisy chained with the current drive, and extra power connectors for an additional drive in the pedestal. But there is a small connector and ribbon connector to the current EDSI disk, but no extra for an additional disk. I take it that the wide connector is a daisy chained data/address bus, while the small connector is a control cable. Can the Emulex handle two EDSI disks, and translate them into two SCSI devices so that I can mount another EDSI disk as /dev/sd1? Or do I need to by another Emulex, and find space for it in the cabinet. Also can the second EDSI disk be a different size/type from the other, or do both have to be identical. Where can I get info on pinouts, jumpers, dip switches, cabling etc for this all?
