Parallel Library TCP/IP
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.
Parallel Library TCP/IP. An HP product that provides increased performance and scalability
over conventional Transmission Control Protocol/Internet Protocol (TCP/IP). Parallel
Library TCP/IP coexists with conventional TCP/IP on HP NonStop S-series systems
and supports Ethernet 4 ServerNet adapters (E4SAs), Fast Ethernet ServerNet
adapters (FESAs), and ServerNet wide area network (SWAN) concentrators. See also
HP NonStop TCP/IP.
persistence. The capability of a generic process to restart automatically if it was stopped
abnormally.
PMF CRU. See processor multifunction (PMF) CRU.
PMF 2 CRU. See processor multifunction (PMF) 2 CRU.
port. (1) A data channel that connects to other devices or computers. (2) A connector to
which a cable can be attached. The system transmits and receives data or requests
through ports on ServerNet adapters and processor multifunction
customer-replaceable units (PMF CRUs). 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.
processor multifunction (PMF) CRU. (1) An HP NonStop S-series customer-replaceable
unit (CRU) that contains a power supply, service processor (SP), ServerNet router 1,
Ethernet controller, three ServerNet addressable controllers (SACs), and a processor
and memory system in a single unit. The PMF CRU consists of three subassemblies:
the processor and memory board (PMB), the multifunction I/O board (MFIOB), and the
power supply subassembly. (2) A collective term for both PMF CRUs and PMF 2
CRUs when a distinction between the two types of CRUs is not required.
processor multifunction (PMF) 2 CRU. An HP NonStop S-series customer-replaceable
unit (CRU) that contains a power supply, service processor (SP), ServerNet router 2,
Ethernet controller, three ServerNet addressable controllers (SACs), and a processor
and memory system in a single unit. The PMF 2 CRU consists of three subassemblies:
