Glossary assignable resource Blade complex Current Partition Specification Deconfigured EFI fast_init I/O Bay ILM Indicted IOH or I/O Hub IOX nPartition NVRAM Partition Memory Partition Number SLM UEFI UEFI Front Page vPar The resources that a customer can designate to be assigned to a partition. 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. 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. 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. 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. Extensible Firmware Interface. 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. 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. Interleaved Memory. Is implemented as Partition Memory in HP Superdome 2, which includes Direct Access Partition Memory and Agent Access Partition Memory 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. The term specifies the PCIe I/O hub chip under the blade or iobay. 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. 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. 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. The memory that is interleaved across all the blades in an nPartition. A unique numeric value assigned to a partition. Socket Local Memory. Interleaved across the memory controllers of a single CPU socket. SLM replaces the concept of cell local memory on cellular servers. Unified Extensible Firmware Interface is an industry specification that defines the interface between an operating system and platform firmware. 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. 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. 108 Glossary
