Glossary  


This glossary defines key terms in the context of an OpenVMS computing environment.

Advanced Server for OpenVMS  Supported on OpenVMS Alpha systems only, an OpenVMS-based network operating system compatible with Microsoft networking technology. Allows OpenVMS systems to be file and print servers for Windows desktop users. These users can use Microsoft products and utilities such as Windows Explorer to access file and print resources. Also provides a flexible system for network administration and security. This product supports OpenVMS ODS-5 disk volumes and Extended File Specifications.PATHWORKS for Advanced Server (OpenVMS)

Availability Manager  A system management tool that enables the system manager to monitor one or more OpenVMS nodes on an extended local area network (LAN) from an OpenVMS, Windows 2000, or Windows XP system. Availability Manager helps system managers and analysts target a specific node for analysis. The tool collects system and process data from multiple nodes simultaneously; it analyzes the data and displays the output. The Availability Manager (base) software installed with OpenVMS provides the data collection components that allow the system to be monitored by the Availability Manager and by DECamds.

Baseboard Management Controller (BMC)  A utility provided with HP Integrity servers that allows you to control some management features built into the system board, such as diagnostics, configuration, and hardware management. It enables you to interact with the Extensible Firmware Interface (EFI) and to boot the OpenVMS operating system.Extensible Firmware Interface (EFI), Management Processor (MP)

BIB  Boot-is-blocked. The state of a cell (on a cell-based Integrity server) that is powered on but not allowed to boot. When all cells assigned to an nPartition are at the BIB state, the nPartition is inactive and no software can run on the nPartition until it is manually booted past BIB. cell, nPartition

boot, bootstrap  The process of loading system software into a processor's main memory. This guide uses the term boot to refer to this process.

boot server  A TCP boot server (TCP/IP Services for OpenVMS BOOTP server) is the host that centralizes configuration and management of an IP address database, such as is used for OpenVMS InfoServer clients.InfoServer

cell  Also known as a cell board: a circuit board that is the basic building block of an nPartition in a server complex (such as any HP midrange and high-end Integrity servers). A cell consists of a symmetric multiprocessor and memory. cell-based server, nPartition (node partition), server complex, virtual partition

cell-based server  A hardware complex that can run one or more operating systems and that supports dividing hardware resources into nPartitions. All processors and memory are contained in cells, each of which can be assigned for exclusive use by an nPartition.cell, nPartition (node partition), server complex, virtual partition

Common Data Security Architecture (CDSA)  A multiplatform, Open Source security infrastructure. CDSA provides a stable, standards-based programming interface that enables applications to access operating system security services. With CDSA, you can create cross-platform, security-enabled applications. CDSA is automatically installed with the operating system. For more information about CDSA, refer to the HP Open Source Security for OpenVMS, Volume 1: Common Data Security Architecture manual.

MP is available even when the server main power switch is in the off position. On entry-class Integrity servers, MP is known as the Integrated Lights-Out (iLO) Management Processor.Baseboard Management Controller (BMC), Extensible Firmware Interface (EFI)

media  Any packaging agents capable of storing computer software (for example, compact discs, magnetic tapes, floppy disks, disk packs, and tape cartridges).

migration support  In OpenVMS Clusters, migration support means that HP has qualified the versions for use together in configurations that are migrating in a staged fashion to a newer version of OpenVMS VAX, OpenVMS Alpha, or OpenVMS I64. Problem reports submitted against these configurations are answered by HP. However, in exceptional cases HP might request moving to a warranted configuration as part of the solution. Migration support helps customers move to warranted OpenVMS Cluster pairs.warranted support

MOP server  A computer system using either the LAN Auxiliary Control Process (LANACP) or DECnet software to downline-load systems using the Maintenance Operations Protocol (MOP). Systems loaded include OpenVMS systems, print servers, and LAT servers.Maintenance Operations Protocol (MOP)

nPartition (node partition)  A hard partition within a cell-based server that provides both hardware and software isolation among different instances of the operating system running on a single server. Cell-based servers can be configured either as a single, large, symmetric multiprocessor or as several independent systems.

virtual partition  A soft partition within a cell-based server that can provide software isolation among different instances of the operating system running on a single server or nPartition. Cell-based servers can be configured either as a single large symmetric multiprocessor or as several independent systems. A virtual partition uses a subset of the system processor, memory, and I/O resources, and includes operating system and application-related software. The HP-UX operating system is the only operating system that can run in a virtual partition.cell, partition, nPartition (node partition), server complex

volume shadowing  The software that performs disk mirroring operations using a redundant array of independent disks (RAID) 1 storage strategy. Provides high data availability for disk devices by ensuring against data loss that results from media deterioration or controller or device failure. This prevents storage subsystem component failures from interrupting system or application tasks. Volume Shadowing for OpenVMS is available as both a separately licensed product on Integrity server systems and a component of the Enterprise Operating Environment (EOE) on Integrity servers.
