| SCSI Bus | A host adapter and one or more SCSI peripherals connected by cables |
| in a linear chain configuration. The host adapter may exist anywhere on |
| the chain, allowing connection of both internal and external SCSI |
| devices. A system may have more than one SCSI bus by using multiple |
| host adapters. |
| SCSI Device | Any device that conforms to the SCSI standard and is attached to the |
| SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI |
| peripherals. |
| SCSI ID | A way to uniquely identify each SCSI device on the SCSI bus. Each |
| SCSI bus has eight available SCSI IDs numbered 0 through 7 (or 0 |
| through 15 for Wide SCSI). The host adapter usually gets the highest ID, |
| (7 or 15) giving it priority to control the bus. |
| SDMS | Storage Device Management System. An LSI Logic software product that |
| manages SCSI system I/O. |
A hardware specification for connecting SCSI devices. It references each | |
SCSI | SCSI signal to a common ground. This is the most common method (as |
| opposed to differential SCSI which uses a separate ground for each |
| signal). |
| STA | SCSI Trade Association. A group of companies that cooperate to |
| promote SCSI parallel interface technology as a viable mainstream I/O |
| interconnect for commercial computing. |
