processor
processor. (1) A functional unit of a computer that reads program instructions, moves data
between processor memory and the input/output controllers, and performs arithmetic
operations. Processors are sometimes referred to as central processing units (CPUs),
but a HP NonStop system has multiple cooperating processors rather than a single
CPU. (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 enclosure. A HP NonStop S-series system enclosure containing exactly 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) A 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. A 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.
PROFILE object type. The Subsystem Control Facility (SCF) object type for the storage
subsystem configuration profile.
PUP. See Peripheral Utility Program (PUP).
RESTORE. A utility for the HP NonStop range of servers that copies files from a backup
tape to disk. See also BACKUP.
robot. A media-changer device that transfers an tape cartridge from a storage cell to a drive
for use, then returns the cartridge to the storage cell.
SAC. See ServerNet addressable controller (SAC).
SAN. System area network. The preferred term is fabrics (see fabric).
SCF. See Subsystem Control Facility (SCF).
SCSI. See small computer system interface (SCSI).
SCSI object type. The Subsystem Control Facility (SCF) object type for the Open SCSI
object.
