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:
the processor and memory board (PMB), the multifunction I/O board (MFIOB), and the
power supply subassembly.
protocol. A set of rules used by processes or devices for exchanging data.
SAC. See ServerNet addressable controller (SAC).
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
systems; and return reply messages to the clients or requesters. A server process is a
running instance of a server program.
ServerNet adapter. A customer-replaceable unit (CRU) that connects peripheral devices to
the rest of the system though a ServerNet bus interface (SBI). A ServerNet adapter is
similar in function to an I/O controller logic board (LB) and backplane interconnect card
(BIC) in other HP NonStop systems. A GESA is a ServerNet adapter.
ServerNet addressable controller (SAC). An I/O controller that is uniquely addressable by
a ServerNet ID in a ServerNet system area network (ServerNet SAN). A SAC is
typically implemented on some portion of a processor multifunction (PMF)
customer-replaceable unit (CRU), an I/O multifunction (IOMF) CRU, or a ServerNet
adapter.
