Max No. of Disks Per SCSI Card for Optimum Performance
SCSI Tapes
Up to seven magnetic tape units may be configured on a single SCSI interface card. However, no high
volume I/O devices, such as disks, should be configured on the same SCSI interface card.
SCSI Printers
For medium to heavy printing on a SCSI printer, it is recommended that only one printer be configured to
a single SCSI interface card. Further, it is recommended that a SCSI printer not share the same SCSI
interface card with any other peripherals.
