LUN Logical Unit Number. An identifier, zero to seven, for a logical unit.
LVDlink Low Voltage Differential Link. Allows greater Ultra3 SCSI device
connectability and longer SCSI cables. LVDlink technology lowers the
amplitude of noise reflections and allows higher transmission
frequencies. Detailed information may be found in
Section 1.4, “LVDlink™ Technology Benefits,” on page 1-5.
Mbyte Megabyte. A measure of computer storage equal to 1024 kilobytes.
NVRAM Nonvolatile Random Access Memory. Actually, an Electronically Erasable
Read Only Memory (EEPROM) chip that stores configuration
information. See EEPROM.
Operating
System A program that organizes the internal activities of the computer and its
peripheral devices. An operating system performs basic tasks such as
moving data to and from devices, managing information in memory, and
providing the user interface.
PCI Peripheral Component Interconnect. A local bus specification that allows
connection of peripherals directly to computer memory. It bypasses the
slower ISA and EISA buses.
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 Bus A host adapter and one or more SCSI devices 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.
SCSI Device Any device that conforms to the SCSI standard and is attached to a SCSI
bus by a SCSI cable. This includes SCSI host adapters, SCSI disk
drives, and other kinds of SCSI devices.
SCSI ID A unique identifier for 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 is normally assigned 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.
