LUN
LUN. See logical unit number (LUN).
NonStop S-series servers. The set of servers in the NonStop range of servers having
product numbers beginning with the letter “S.” These servers implement the ServerNet
architecture and run the HP NonStop Kernel operating system.
operator message. A message, intended for an operator, that describes a significant event
on a NonStop S-series system. An operator message is the displayed-text form of an
Event Management Service (EMS) event message. See also event message.
OSM. Stands for HP NonStop Open System Management (OSM) Interface. Replaces TSM
as the system management tool of choice for NonStop S-Series servers. Provides the
same functionality as TSM while overcoming limitations of TSM. OSM is required for
support of new functionality released with the G06.21 RVU and later.
port. (1) A data channel that connects to other devices or computers. (2) A connector to
which a cable can be attached. A port is also called a connector. (3) The entrance or
physical access point (such as a connector) to a computer, multiplexer, device, or
network where signals are supplied, extracted, or observed.
primary processor. The processor that is designated as “owning” the ServerNet
addressable controller (SAC) connected to separate processors running the HP
NonStop Kernel operating system. The primary processor is the processor that has
direct control over the SAC. Contrast with backup processor.
processor. (1) The central processing unit (CPU). The processor reads program
instructions, moves data between processor memory and the ServerNet addressable
controllers (SACs), and performs arithmetic operations. (2) One or more computer
chips, typically mounted on a logic board, that are designed to perform data processing
or to manage a particular aspect of computer operations.
protocol. A set of rules used by processes or devices for exchanging data.
SAC. See ServerNet addressable controller (SAC)
.
SAN. See storage area network (SAN)
.
SC. See Subscriber Channel (SC).
SCF. See Subsystem Control Facility (SCF).
server. (1) An implementation of a system used as a stand-alone system or as a node in an
Expand network. (2) A combination of hardware and software designed to provide
services in response to requests received from clients across a network. For example,
the NonStop range of servers provides transaction processing, database access, and
other services. (3) A process or program that provides services to a client or a
requester. Servers are designed to receive request messages from clients or
requesters; perform the desired operations, such as database inquiries or updates,
security verifications, numerical calculations, or data routing to other computer
