SCAM

SCSI Configured AutoMatically. A method to automatically allocate SCSI

 

IDs using software when SCAM compliant SCSI devices are attached.

SCSI

Small Computer System Interface. A specification for a high-performance

 

peripheral bus and command set. The original standard is referred to as

 

SCSI-1.

SCSI-2

The SCSI specification which adds features to the original SCSI

 

standard.

SCSI-3

The current SCSI specification which adds features to the SCSI-2

 

standard.

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.

SCSI SCRIPTS

A SCSI programming language that works with the SCRIPTS processor

 

that is embedded on the LSI53C1010-33 device. These SCRIPTS reside

 

in the host computer system memory.

SCRIPTS Processor

The SCRIPTS processor allows users to fine tune SCSI operations with regard to unique vendor commands or new SCSI specifications. The SCRIPTS processor fetches SCRIPTS instructions from system memory to control operation of the LSI53C8XX device.

SDMS

Storage Device Management System. An LSI Logic software product that

 

manages SCSI system I/O.

Single-Ended

A hardware specification for connecting SCSI devices. It references each

(SE) 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).
