6.6.2 External SCSI Expansion
External SCSI devices, such as tabletop or rackmounted storage devices, can be
connected to the system using EISA- or PCI-based SCSI adapters. Use the following
rules to determine if a particular device can be used:
• The device must be supported by the operating system. Consult the software
product description for the device or contact the hardware vendor.
• A maximum of seven devices can be attached on any one SCSI controller.
• Each device on the bus must have a unique SCSI ID. You may need to change a
device's default SCSI ID in order to make it unique. For information about
setting a device's ID, refer to the guide for that device.
• The entire SCSI bus length, from terminator to terminator, must not exceed 6
meters for fast double-ended SCSI, or 3 meters for fast single-ended SCSI.
• Ensure that the SCSI bus is properly terminated and that no devices in the
middle of the bus are terminated.
• For best performance, wide devices should be operated in wide SCSI mode.
