RISC Core Symbios SCSI chips contain a RISC (Reduced Instruction Set
Computer) processor, programmed through microcode scripts.
RJ-45: The name for the connector type used with UTP cabling.
ROM (Read-Only Memory) Memory from which information can be read but
not changed. The contents of ROM are not erased when the computer is turned off.
SCAM (SCSI Configured AutoMatically) A method to automatically allocate
SCSI IDs via 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 now referred to as SCSI-1.
SCSI-2 The current SCSI specification that adds features to the original SCSI-1
standard.
SCSI-3 The next SCSI specification, that 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 conforming to the SCSI standard that attaches to the SCSI
bus by means of a SCSI cable. This includes SCSI host adapters and SCSI
peripherals.
SCSI ID A unique identification for each SCSI device on the SCSI bus. Each SCSI
bus has fifteen available SCSI IDs numbered 0 through 15 for Wide SCSI or 0-7 for
8-bit SCSI. The host adapter is assigned ID 7, which gives it priority to control the
bus.
SDMS (SCSI Device Management System) A Symbios software product
that manages SCSI system I/O.
Single-Ended SCSI A hardware specification for connecting SCSI devices. It
references each SCSI signal to a common ground, as opposed to differential SCSI
and low-voltage differential SCSI, which use a separate return for each signal.
Subnetwork: Small discrete physical networks connected via gateways
