NFS client
In a NFS client configuration, the host system provides UNIX file systems for the client
system. A client system operates as a diskless NFS client of a host system.
NIS
Network Information Service (formerly called yellow pages or yp). NIS is an administrative system. It provides central control and automatic dissemination of important administrative files.
NVRAM
Non-Volatile Random Access Memory. This type of memory retains its state even after
power is removed.
P0*PCI (P0Bus)
The PCI-to-PCI (P0) hardware bus interface that provides improved SBC board-to-board
performance. The P0Bus is 64 bits wide and operates at 33 MHz, for a theoretical
maximum of 264 MB/sec. This is more than three times the theoretical maximum of the
standard VME64 bus of 80 MB/sec. The Power Hawk Series 700 P0Bus interface is based
on the Intel 21554 64-bit PCI-to-PCI bridge chip.
The P0Bus hardware is required for Power Hawk Series 720/740 Closely Coupled
configurations, where the P0Bus is used for Closely Coupled inter-SBC communications.
P0*PCI (P0Bus) Overlay
A P0*PCI connector board, which is used to connect multiple SBCs in the same cardcage
(cluster) to a common P0Bus.
panic
The state where an unrecoverable error has occurred. Usually, when a panic occurs, a message is displayed on the console to indicate the cause of the problem.
PDU
Protocol Data Unit
PowerPC G4
The PowerPC G4 (7400) microprocessor. Part of the PowerPC family of microprocessors;
an architecture based on Motorola/IBM's 32-bit RISC design CPU core.
PPP
Point-to-Point protocol is a method for transmitting datagrams over point-to-point serial
links
