Glossary
Assignable
Resource
Refers to the resources that a customer can designate to be assigned to a partition.
Blade
A board that contains CPUs and memory and 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
Specification
Is the parspec that is currently associated with the instance of the nPartition defined by the
parspec. 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.
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.
I/O eXpansion
chassis (IOX)
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.
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
correctable problem. Such a resource is marked for indictement by the Health Repository on
the OA, and parcon reports the health of such resources as Indicted.
nPartition
Is 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. A HP Superdome 2 nPar is very much like an nPar
on cellular servers.
Partition Memory
The memory that is interleaved across all of the blades in an nPartition.
Partition Number
A unique numeric value assigned to a partition.
Socket Local
Memory (SLM)
Is memory that is interleaved across the memory controllers of a single CPU socket. SLM replaces
the concept of cell local memory on cellular servers.
Virtual Partition
(vPar)
Is 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. A HP Superdome 2 vPar is very much like a vPar on
cellular servers, though on HP Superdome 2 there is no vPars monitor.
