protocol
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).
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.
ServerNet LAN Systems Access (SLSA) subsystem. The software that allows the
protocol I/O processes (IOPs) and drivers to access the ServerNet adapters.
ServerNet SAN. See ServerNet system area network (ServerNet SAN).
ServerNet system area network (ServerNet SAN). A wormhole-routed, full-duplex,
packet-switched, point-to-point network designed with special attention to reducing
latency and ensuring reliability. The ServerNet SAN provides the communication path
used for interprocessor messages and for communication between processors and I/O
devices.
ServerNet wide area network (SWAN) concentrator. (1) An HP data communications
peripheral that provides connectivity to an HP NonStop S-series system. The SWAN
concentrator supports both synchronous and asynchronous data over RS-232,
RS-449, X.21, and V.35 electrical and physical interfaces. (2) A collective term for
both SWAN concentrators and SWAN 2 concentrators when a distinction between the
two is not required.
ServerNet wide area network (SWAN 2) concentrator. An HP data communications
peripheral that provides connectivity to an HP NonStop S-series system. The SWAN 2
concentrator supports both synchronous and asynchronous data over RS-232,
RS-449, X.21, and V.35 electrical and physical interfaces. The SWAN 2 concentrator
is the next-generation SWAN concentrator and has 12 WAN ports.
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your HP NonStop S-series system. The Compaq
TSM package allows you to use the help of a service provider by configuring TSM to
support remote notification and remote access.
