SCSI Termination
All SCSI buses require termination on both ends of the bus to prevent signal degradation. The Smart Array 3200 Controller supplies the termination on the origination end of the SCSI bus. All internal SCSI cabling recommended for Compaq servers provides the necessary termination for the opposite end of the bus. Therefore, individual SCSI drives in Compaq servers should not contain bus termination.
External SCSI devices must also provide termination for the SCSI bus. This is supplied in Compaq external storage systems such as the ProLiant Storage System or SCSI Storage Expander. Therefore, individual SCSI drives in Compaq storage systems should not contain bus termination.
SCSI IDs
The Smart Array 3200 Controller contains two SCSI buses (ports), each of which supports up to 15 drives. The internal and external connectors reside on separate SCSI buses; peripherals attached to either connector must have a unique SCSI ID in the ranges of 0 to 6 and 8 to 15. SCSI IDs on all peripherals are either set manually, with switches or jumpers on the device itself, or set automatically on Compaq products that support
