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.

See also 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 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.


Accelerated Virtual Input/Output. An I/O protocol that improves virtual I/O performance for network and storage devices used within the Integrity VM environment. The protocol also enables support for a greater number of virtual I/O devices per guest. Special drivers are required on both the VM Host and guests. Participating guests must include a virtual I/O device configured to use the AVIO protocol.


backing store 

The physical device on the VM Host that is allocated to guests, such as a network adapter, disk, or file.

Base Operating Environment

A process implemented for data confidentiality that converts sensitive or otherwise private data to an unintelligible form called cipher-text. Decryption reverses the process, taking the unintelligible cipher-text and converting the data back into its original form, called plaintext. Encryption and decryption are also known as encipher and decipher. Encryption for OpenVMS software is based on the Advanced Encryption Standard (AES) alogrithm and is integrated with the operating system. This allows OpenVMS users, system managers, security managers, or programmers to secure their files, save sets, or application data with AES Encryption.

Instant Capacity. Supported on cell-based Integrity servers, the HP Utility Pricing Solutions product that allows you to purchase and install additional processing power through the use of a two-step purchase model. Initially, you purchase system components (cores, cell boards, memory) at a fraction of the regular price because the usage rights are not included. These Instant Capacity components are inactive but installed and ready for use. When extra capacity is needed, you pay the remainder of the regular price for the usage rights to activate the components. If the regular price for the component is reduced by the time the usage rights are purchased, the remainder price is proportionally reduced, providing additional savings. After obtaining usage rights, Instant Capacity cores can be turned on by the Instant Capacity software or during installation.

Earlier versions of iCAP were referred to as Instant Capacity on Demand, or iCOD.

See also TiCAP.


See MP.


A general-purpose disk storage server (virtual device server). It can make devices available to client systems on the LAN.

OpenVMS Version 8.4 adds support for the iLO Integrated Console capability provided by Integrity Servers and blades systems supporting iLO. The enabling functionality that provides this support is referred to as “virtual Keyboard, Video, and Mouse” or vKVM. The feature allows you to connect a virtual serial line from your PC to Integrity servers, enabling your PC, keyboard, and mouse to function as if directly connected to the server. Your window displays the contents of the Integrity server's VGA.


Virtual Media. A virtual-disk capability included with iLO MP 2 on Integrity servers. vMedia provides virtual devices that mimic physical hardware devices. For example, it can provide a virtual CD/DVD drive that connects over the network to your Integrity servers as if it were physically connected. You can use vMedia to install OpenVMS on Integrity servers that do not include a built-in DVD drive. vMedia can provide the network service for HP SIM provisioning, or it can be used independently of HP SIM.

See also HP SIM, provisioning.

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.

WBEM Providers for OpenVMS 

Available on OpenVMS Integrity server systems, a product that enables (along with WBEM Services for OpenVMS) HP Systems Insight Manager (HP SIM) management of the operating system. HP SIM uses WBEM providers to perform such functions as identifying the operating system on the managed system, associating the virtual or physical instances to their respective containers, providing inventory and reports on hardware and software configurations, and monitoring the system remotely for hardware faults.

See also provisioning, WBEM Services for OpenVMS, HP SIM.

WBEM Services for OpenVMS 

A product available on OpenVMS Integrity server systems that provides an industry-standard enterprise management framework and resource description. WBEM’s structured framework is capable of being extended and uses management and Internet standards. Developers of management applications can take advantage of previously done work that exposes resource information and operations; for example, developers can take code that was developed for a specific platform or application and use it with WBEM for the same purposes—WBEM is platform-neutral, enabling reuse of infrastructure, tools, and applications. WBEMCIM is the WBEM Services for OpenVMS file name used in the PCSI kit. CIM stands for the Common Information Model, which differentiates the current OpenVMS WBEM product from the original one that is based on the Simple Network Management Protocol (SNMP).
