AAA-130U2 Series Installation and Hardware Guide External SCSI Array Enclosures (Storage Subsystems) To help you conveniently manage your SCSI storage subsystems, a variety of external array enclosures are available from different manufacturers. Figure 2-16 shows a typical setup between the array enclosure and the system. To install your SCSI devices in these enclosures, refer to the enclosure's documentation. The following information is provided to help you properly connect your enclosure to the system: (See the Adaptec Web site at http://www.adaptec.com/raid for a list of popular array storage enclosures and disk drive manufacturers.) s All rules for SCSI ID and termination must be followed when installing SCSI device in an array enclosure. s Ideally, the array enclosure itself should provide termination capability, either on the SCSI backplane or with an attachable active terminator, as shown in Figure 2-16, and you should disable termination on all the drives in the enclosure. If you terminate the SCSI bus by enabling termination on a drive, you may run into problems if you have to replace that drive and you then forget to terminate the replacement drive. s If the enclosure you are using for the array drives is not specifically designed as a array enclosure (such as a standard tower unit), be sure it has adequate cooling and ventilation.
