Glossary

assignable The resources that a customer can designate to be assigned to a partition.
resource
Blade A board that contains CPUs, memory, slots for C-class mezzanine cards, and onboard NICs. A
blade is the equivalent of a cell in terms of being the unit of assignment for defining nPartitions.
complex A collection of blade enclosures and IOXs cabled together and under the control of a single
active, monarch OA (ignoring OA failures). For example, the smallest possible HP Superdome
2 complex is a single enclosure with no external IOX; the largest possible HP Superdome 2
complex is four enclosures with the maximum number of external IOXs.
Current Partition The parspec that is currently associated with the instance of the nPartition defined by the parspec.
Specification Changes to the parspec are also reflected as changes to the nPartition, and vice versa.
Deconfigured The term used to describe the health of a resource that has been marked as unusable by the
Health Repository. Such a resource will be excluded from partition activity.
EFI Extensible Firmware Interface.
fast_init A configurable setting from UEFI to control I/O driver connection during partition boot. The UEFI
Shell ioconfig command can be used to view and change the fast_init setting, however turning
fast_init OFF is not recommended.
I/O Bay An I/O bay consists of an IOH and the associated set of root complexes and corresponding root
ports. Each I/O bay in a BIOX can be assigned to a different nPartition.
ILM Interleaved Memory. Is implemented as Partition Memory in HP Superdome 2, which includes
Direct Access Partition Memory and Agent Access Partition Memory
Indicted The term used to describe the health of a resource that might be exhibiting symptoms of a problem
that can be corrected. Such a resource is marked for indictement by the Health Repository on the
OA, and parcon reports the health of such resources as Indicted.
IOH or I/O Hub The term specifies the PCIe I/O hub chip under the blade or iobay.
IOX I/O eXpansion chassis. A unit that can be added to a HP Superdome 2 complex (via connections
to the XBAR backplane and CAMNET) to add I/O slots to the complex.
nPartition A partition that is assigned one or more blades and optionally zero or more I/O bays. An
nPartition can run a single OS (either a standalone OS or an HPVM host), or an nPar can be
sub-divided into customer-defined vPars. An HP Superdome 2 nPar works like an nPar on cellular
servers.
NVRAM Non-volatile random-access memory is RAM that retains its information when power is turned off,
and is used to store settings that must remain available on the next boot.
Partition Memory The memory that is interleaved across all the blades in an nPartition.
Partition Number A unique numeric value assigned to a partition.
SLM Socket Local Memory. Interleaved across the memory controllers of a single CPU socket. SLM
replaces the concept of cell local memory on cellular servers.
UEFI Unified Extensible Firmware Interface is an industry specification that defines the interface between
an operating system and platform firmware.
UEFI Front Page The first user interface provided during partition boot to UEFI. It allows users to stop automatic
boot entry execution, and interact with UEFI. For example, launch the UEFI Shell command line
interface.
vPar Virtual Partition. A partition that exists within an nPar. A vPar is assigned CPU cores, ranges of
ILM and SLM, and root ports from the containing nPar. An HP Superdome 2 vPar works like a
vPar on cellular servers, except that there is no vPars monitor on HP Superdome 2.
