Refer to the HP TCP/IP Services for OpenVMS Software Product Description (SPD 46.46.xx) for further informa- tion.

HP DECnet-Plus and HP DECnet Software

HP DECnet for OpenVMS Alpha and Integrity server software is a System Integrated Product (SIP). DEC- net for OpenVMS Alpha is licensed separately from the OpenVMS operating system. DECnet for OpenVMS for Integrity servers is a component of the Foundation Op- erating Environment (FOE) on Integrity servers license bundle.

HP DECnet-Plus (formerly DECnet/OSI) for OpenVMS Alpha is licensed separately from the OpenVMS oper- ating system as well. DECnet-Plus for OpenVMS for In- tegrity servers is a component of the Foundation Operat- ing Environment (FOE) on Integrity servers license bun- dle. The license for DECnet for OpenVMS Alpha and OpenVMS for Integrity servers also grants the rights to use DECnet-Plus. Note that only one version of DECnet can be active on a single system at any one time. Both DECnet and DECnet-Plus allow OpenVMS systems to participate in network task-to-task communications for the purposes of transfer and copy of files, printing, the running of applications, etc.

DECnet-Plus offers task-to-task communications, file management, downline system and task loading, net- work command terminals, and network resource shar- ing capabilities as defined in the DIGITAL Network Ar- chitecture (DNA) Phase V protocols. DECnet-Plus pro- vides the newest DECnet features such as extended addressing and downline-load performance enhance- ments. DECnet-Plus integrates DECnet and OSI pro- tocols and now provides a linkage to TCP/IP using Request for Comments (RFC) 1006 and RFC 1859. DECnet and OSI applications can now be run over DEC- net (NSP), OSI (CLNS), and TCP/IP transports.

DECnet for OpenVMS Alpha offers the networking ca- pabilities as defined in the DIGITAL Network Architec- ture (DNA) Phase IV. For more information, refer to the Associated Products section of this SPD.

Refer to the DECnet-Plus for OpenVMS Software Prod- uct Description (SPD 50.45.xx), or the DECnet for Open- VMS Software Product Description (SPD 48.48.xx) for further information.

HP DECram for OpenVMS

HP DECram for OpenVMS is a disk device driver that improves I/O performance by allowing an OpenVMS system manager to create pseudo disks (RAMdisks) that reside in main memory. Frequently accessed data can be accessed much faster from a DECram device than from a physical disk device. These RAMdisks can be accessed through the file system just as physical disks are accessed, requiring no change to application or system software.

Because main memory is allocated for the DECram device, extra memory is generally required. The OpenVMS system manager can designate the amount of memory dedicated to the DECram devices and the files that will be stored on it.

Starting with HP OpenVMS Version 8.2, the binary kit for HP DECram ships with the HP OpenVMS Alpha and Integrity servers distribution kits. To run the DECram software, customers must first purchase a separate li- cense.

For HP OpenVMS Alpha customers, the software li- censes is: QL-MV3A*-**.

For HP OpenVMS for Integrity server customers, a soft- ware license for HP DECram may be purchased either as part of the OpenVMS Enterprise Operating Environ- ment (EOE) or as a separate per-processor core license (PCL): BA407AC

For more information, refer to the HP DECram for Open- VMS Software Product Description (SPD 34.26.xx).

OpenVMS I64 Operating Systems specifications

HP OpenVMS I64 is a robust operating system originally developed by Digital Equipment Corporation and later acquired by Hewlett-Packard. It stands for "Open Virtual Memory System" and is designed to run on Intel Itanium (I64) architecture, offering high reliability and performance for mission-critical applications.

One of the defining features of OpenVMS is its focus on availability and fault tolerance. It supports clustering, allowing multiple nodes to function together as a single system. This feature ensures that if one node fails, others can continue processing, minimizing downtime. Furthermore, OpenVMS employs a sophisticated method of process management, enabling the efficient handling of multiple tasks and processes simultaneously.

Security is a paramount characteristic of OpenVMS. The system implements a multi-layered security architecture, encompassing user authentication, access controls, and logging features that protect against unauthorized access. It also offers role-based access control, which streamlines permissions and bolsters overall system security.

OpenVMS is compatible with various programming languages and development tools, which makes it a versatile choice for developers. It supports languages like C, C++, COBOL, and Pascal, as well as development environments that facilitate the creation of sophisticated applications. Its comprehensive suite of development and debugging tools enhances productivity and ease of use for software engineers.

Another notable feature is its support for legacy applications. OpenVMS provides compatibility with older systems, allowing organizations to modernize their infrastructure without losing valuable investments in legacy code. This backward compatibility is vital for enterprises that require long-term system integrity and data consistency.

The operating system also features an advanced file system known as the Virtual Memory System (VMS) file system, which supports a variety of file types and efficient data management. The system is designed for high-performance I/O operations, which is crucial for applications that require quick data access and processing.

In terms of networking, OpenVMS supports a range of communication protocols, making it suitable for integration into complex networked environments. Its TCP/IP stack enables seamless connectivity with other platforms, facilitating collaboration in mixed environments.

Overall, HP OpenVMS I64 stands out for its reliability, security, and performance, making it an ideal choice for enterprises demanding a robust operating environment capable of handling their critical workloads. Its combination of advanced features and software support ensures that organizations can continue to innovate while relying on a stable foundation.
