2.4 Configure external peripherals (UPS, external drive subsystems, etc.)
Configure an external disk subsystem
Configure an external CD-ROM system
Configure an Uninterruptible Power Supply (UPS)
This section discusses the configuration of external disk subsystems, external CD-ROM systems, and uninterruptible power supplies. External disk subsystems are necessary when the amount of disk storage cannot be accommodated by the disk drive bays internal to the network server chassis. These external disk subsystems can be either SCSI or Fibre Channel. Generally, Fibre Channel–based systems can support many more disk drives than a SCSI-based external system.
External CD-ROM systems are generally used to implement CD-ROM ...
