serial control bus
A two-conductor serial interconnect that is independent of the system bus. This
bus links the processor modules, the I/O, the memory, the power subsystem, and
the operator control panel.
serial ROM
In the context of the CPU module, ROM read by the DECchip microprocessor
after reset that contains low-level diagnostic and initialization routines.
SIMM
Single in-line memory module.
SRM
User interface to console firmware for operating systems that expect firmware
compliance with the Alpha System Reference Manual (SRM).
storage array
A group of mass storage devices, frequently configured as one logical disk.
StorageWorks
Digital’s modular storage subsystem (MSS), which is the core technology of the
Alpha SCSI-2 mass storage solution. Consists of a family of low-cost mass storage
products that can be configured to meet current and future storage needs.
superscalar
Describes a processor that issues multiple independent instructions per clock
cycle.
symmetric multiprocessing (SMP)
A processing configuration in which multiple processors in a system operate as
equals, dividing and sharing the workload.
symptom-directed diagnostics (SDDs)
An approach to diagnosing computer system problems whereby error data logged
by the operating system is analyzed to capture information about the problem.
system bus
The hardware structure that interconnects the CPU and memory modules. Data
processed by the CPU is transferred throughout the system through the system
bus.
