NS X.25 Migration: NS 3000/V to NS 3000/iX

Differences Between NS 3000/V and NS 3000/iX

Differences Between NS 3000/V and NS 3000/iX

The following paragraphs summarize differences between NS 3000/V and NS 3000/iX. Make sure that you account for these differences that could affect your network when migrating to NS 3000/iX. For information on operating system migration, refer to the MPE/iX Migration series.

Hardware

Some NS 3000/V hardware components are not part of an NS 3000/iX network, such as the ATP for terminal connections, and the INP for network links.

On an NS 3000/iX network, the DTC provides connections for local or remote terminals and serial printers. The DTC also provides MPE/iX access to X.25 through a DTC/X.25 Network Access card. The Datacommunications and Terminal Subsystem (DTS) LANIC on the MPE/iX host is used for system-to-system X.25 connectivity.

Unsupported Network Connections

Before migrating your network, identify any unsupported network connections. The network connections that are not supported on NS 3000/iX networks are as follows:

•Manual-dial modems.

•Asynchronous SERIAL Network Link and bisynchronous link-level protocol. To ease migration, you can convert Asynchronous SERIAL network links to the NS 3000/V Point-to-Point links which can be converted to NS 3000/iX. Point-to-Point links use the LAP-B protocol.

•Connections to DS/3000 nodes. DS network services are not supported on NS 3000/iX. If DS/3000 nodes are part of an existing network, either migrate them to NS 3000/V or maintain NS 3000/V connections to the DS/3000 nodes.

Configuration of Terminals and Printers

On NS 3000/V networks, the SYSDUMP program is used to perform I/O configuration which includes configuring terminals, printers, and other I/O devices and drivers. On NS 3000/iX, terminals and serial printers are configured on the host (using NMMGR) and on the OpenView Windows Workstation (using the OpenView DTC Manager software). For more information on configuration using your OpenView Windows Workstation, read Using the OpenView DTC Manager.

E3000 MPE/IX, E3000/IX specifications

The HP E3000 series, particularly the E3000/IX and E3000 MPE/IX, represents a significant milestone in the evolution of business computing, developed by Hewlett-Packard (HP) during the late 1970s and early 1980s. These systems were designed to provide robust, reliable, and efficient operation for mid-sized businesses, leveraging the power of the MPE (Multi-Programming Executive) operating system.

One of the main features of the HP E3000 series is its multitasking capability. MPE/IX allows for multiple applications to run concurrently, maximizing the utilization of system resources. This is particularly beneficial for organizations that require simultaneous access to various business applications, ensuring enhanced productivity and efficiency.

The HP E3000/IX architecture is built on a powerful 16-bit or 32-bit microprocessor, enabling it to handle substantial workloads. The system architecture is known for its modular design, which allows for easy upgrades and customization. This flexibility is essential for businesses that need to adapt to changing demands without overhauling their entire computing infrastructure.

Another notable technology incorporated into the HP E3000 series is its support for a range of storage solutions. The E3000 systems were compatible with various disk drives, providing organizations with options for data storage that matched their performance and capacity requirements. Additionally, they featured advanced data management capabilities, such as built-in backup and recovery systems, ensuring that critical business information remained secure and accessible.

Beyond hardware capabilities, HP E3000/IX and MPE/IX systems provide extensive programming support. They included tools for developing custom applications, with support for languages such as COBOL, BASIC, and FORTRAN. This versatility made it easier for businesses to tailor their software solutions to their specific needs, enhancing operational effectiveness.

Networking capabilities were also a significant innovation of the E3000 series. The systems offered robust support for various networking protocols, allowing for seamless integration with other computing environments. This facilitated communication and collaboration within an organization, as well as with external partners and clients.

In summary, the HP E3000/IX and E3000 MPE/IX systems were pivotal in delivering reliable computing power to mid-sized enterprises. With their multitasking operating system, modular architecture, advanced data management, and programming support, these systems provided an adaptable and comprehensive solution for evolving business needs. The legacy of the E3000 series is evident in how it paved the way for modern enterprise computing, focusing on flexibility, scalability, and efficiency.
