O
OpenBoot PROM A layer of software that takes control of the configured server from
Power-On Self-Test (POST), builds some data structures in memory, and
boots the operating system. OpenBoot PROM is compliant with IEEE 1275.
Operator Panel (OPNL) A panel containing the LEDs that indicate the condition of the server and the
settings of the POWER and mode switches.
Oracle Solaris OS The Oracle Solaris operating system, which controls and manages the
domains.
P
password policy A set of rules for the creation and maintenance of passwords.
PCI carrier A component used to mount PCI cards in the external I/O expansion unit. The
PCI carrier has a similar function to the PCI cassette used for the SPARC
Enterprise M4000/M5000/M8000/M9000 servers. The PCI carrier, however,
is not compatible with the PCI cassette. See also carrier.
PCI cassette A component used to mount PCI Express (PCIe) cards in an I/O Unit (IOU) of
a SPARC Enterprise M4000/M5000/M8000/M9000 server.
PCI Express (PCIe) A high-speed serial transfer interface. The minimum configuration of the
PCIe transmission line is called a lane. The ports of SPARC Enterprise
M4000/M5000/M8000/M9000 servers consist of eight lanes (x8). PCIe
supports hot plugging.
PCI Hot Plug (PHP) Active addition or removal of a PCI card executed during Oracle Solaris OS
operation.
PCIe See PCI Express (PCIe).
PCIe slot A high-speed serial point-to-point interconnect. The minimum configuration
of the PCIe transmission line is called a lane. A PCIe slot of the SPARC
Enterprise M3000 server consists of eight lanes (x8) of PCI Express bus.
Compared with PCI-X, the PCIe data transfer rates are doubled.
PCI-X A faster version of the parallel bus PCI standard. The PCI-X bus has
improved protocols and a faster clock rate.
