Glossary

SCC Addressing

SCSI-3 Controller Commands (SCC) addressing is used to address SCSI devices attached to the PSFR-CP41 using the SCC logical unit addressing method. In SCC addressing mode, the PSFR-CP41 will respond to FCP commands as in a SCC controller device.

SCSI

Small Computer System Interface. An industry standard for connecting peripheral devices and their controllers to an initiator.

SCSI Adapter

A 16-bit fast/wide differential or 8-bit narrow single-ended physical connection between the PSFR-CP41 and the SCSI devices. Each SCSI adapter supports up to sixteen (for fast/wide) or eight (for narrow) SCSI devices, including itself.

SCSI Addressing

A fast/wide SCSI adapter supports up to 16 devices, including itself. Each device has its own unique SCSI address. The SCSI address of a device dictates the device’s priority when arbitrating for the SCSI bus. SCSI address ”7” has the highest priority. The next highest priority address is ”6” followed by 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, with ”8” being the lowest priority address.

The fast/wide SCSI adapter is factory set to address 7. A narrow SCSI adapter supports up to eight devices, including itself. SCSI address ”7” has the highest priority followed by 6, 5, 4, 3, 2, 1, and 0.

SCSI Bus

The means of transferring SCSI data between SCSI devices. It is an 8-bit or 16-bit bus that supports up to eight or sixteen devices (including itself), in any mix of initiators and targets, with the limitation that at least one initiator and one target must be present.

SCSI Device

A single unit on the SCSI bus, identifiable by a unique SCSI address. A SCSI device can act as an initiator or target. For SCSI-3, each SCSI device supports up to sixteen LUNs.

SCSI Port

An opening at the back of the PSFR-CP41 providing connection between the SCSI adapter and the SCSI bus.
