processor and memory board (PMB)
processor and memory board (PMB). A logic board that has lockstepped
microprocessors, the main memory system, and the ServerNet memory interface (SMI)
application-specific integrated circuits (ASICs) to act as an interface between the
microprocessors and memory and the ServerNet fabrics. This board is part of the
processor multifunction (PMF) customer-replaceable unit (CRU).
processor cache. Small, fast memory holding recently accessed data in order to speed up
subsequent access to the same data. Cache memory is built from faster memory chips
than main memory. It is most often used with process or main memory but is also used
in network data transfer (to maintain a local copy of data) and so forth.
processor dump. A copy of the memory of a processor. A dump can be to disk or to tape.
See also ServerNet dump and tape dump.
processor enclosure. An HP NonStop™ S-series system enclosure containing one group,
which includes processors, ServerNet adapters, disk drives, components related to the
ServerNet fabrics, and components related to electrical power and cooling for the
enclosure.
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:
the processor and memory board (PMB), the multifunction I/O board (MFIOB), and the
power supply subassembly.
product module (PM). The part of the Subsystem Control Facility (SCF) subsystem that is
responsible for subsystem-specific command processing.
profile. Default values used by the Distributed Systems Management/Software
Configuration Manager (DSM/SCM) when processing requests. The three types of
profiles are the Configuration Manager profile, the system profile, and the target profile.
PROFILE object type. The Subsystem Control Facility (SCF) object type for the storage
subsystem configuration profile.
program. See program file.
program file. An executable object code file containing a program’s main routine plus
related routines statically linked together and combined into the same object file. Other
