Software Product Description and Quickspecs
VSI OpenVMS Alpha Version 8.4-2L2 Operating System DO-DVASPQ-01A Software Product Description and QuickSpecs PRODUCT NAME: VSI OpenVMS Alpha Version 8.4-2L2 DO-DVASPQ-01A This SPD and QuickSpecs describes the VSI OpenVMS Alpha Performance Release Operating System software, Version 8.4-2L2 (hereafter referred to as VSI OpenVMS Alpha V8.4-2L2). DESCRIPTION OpenVMS is a general purpose, multiuser operating system that runs in both production and development environments. VSI OpenVMS Alpha Version 8.4-2L2 is the latest release of the OpenVMS Alpha computing environment by VMS Software, Inc (VSI). VSI OpenVMS Alpha V8.4-2L2 is compiled to take advantage of architectural features such as byte and word memory reference instructions, and floating-point improvements, which are available only in HPE AlphaServer EV6 or later processors. This optimized release improves performance by taking advantage of faster hardware-based instructions that were previously emulated in software. NOTE: VSI OpenVMS Alpha V8.4-2L2 does not work on, and is not supported on, HPE AlphaServer pre-EV6 systems. OpenVMS Alpha supports HPE’s AlphaServer series computers. OpenVMS software supports industry standards, facilitating application portability and interoperability. OpenVMS provides symmetric multiprocessing (SMP) support for multiprocessing systems. The OpenVMS operating system can be tuned to perform well in a wide variety of environments. This includes combinations of compute-intensive, I/O-intensive, client/server, real-time, and other environments. Actual system performance depends on the type of computer, available physical memory, and the number and type of active disk and tape drives. The OpenVMS operating system has well-integrated networking, distributed computing, client/server, windowing, multi-processing, and authentication capabilities.

Networking Standards Mark Davies, Digital Equipment Corporation
N92-12499 Networking Standards Mark Davies, Digital Equipment Corporation ABSTRACT The enterprise network is currently a multivendor environment consisting of many defacto and proprietary standards. During the 1990s, these networks will evolve towards networks which are based on international standards in both the LAN and WAN space. Also, you can expect to see the higher level functions and applications begin the same transition. The Open Network Advantage Market Requirements OPEN NETWORKS!!! Multi-protocol, multi-platform, multi-vendor networks working together International AND defacto standards Effortless communications within and between enter- prises Ability to move to standards at own pace What is an Open System? Defined as: A vendor-neutral computing environment: - compliant with International and defacto standards - permits system and network interoperability or software applications portability - includes consistency of data and human access - satisfies one or more of a business's functional requirements Standards Benefits from networks based on international and defacto standards o Vendor independence o Applications portability o Investment protection o Improved communications leading to increased productivity o Network flexibility 13DSDDED Network Architectures: DECnet, OSI, TCP/IP DECnet OS) IP Application Application Internet Applications Protocols Presentation DMA Session Control Session Transport Transport Transport (NSP) (TP 0,2,4) (TCP / UDP) Network Network Network (CLNS) (CLNS/CONS) (IP) Data Link Data Link Data Link
