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

Differences Between NS 3000/V and NS 3000/iX

PAD devices on NS 3000/V are configured (using NMMGR) as part of the X.25 network configuration. On NS 3000/iX when PC-based network management is used, PAD devices are configured both on the host (using NMMGR) and on the OpenView Windows Workstation (using the OpenView DTC Manager software).

Configuration Files

NS 3000/V network configuration files are separated into two files, the NMCONFIG file, which contains link information, and the NSCONF file, which contains the transport configuration and other subsystems you have purchased such as SNA.

NS 3000/iX systems have a single NMCONFIG.PUB.SYS file that contains information for the network transport, for NetIPC and link-level logging, and also for the Datacommunications and Terminal Subsystem (DTS). NMCONFIG.PUB.SYS also contains information for any other subsystems you have purchased such as SNA.

Network Services

Differences in the support of network services between NS 3000/V and NS 3000/iX can affect applications that users may currently be running on the NS 3000/V network. These differences are:

•NS 3000/iX supports PTOP for HPDESK only. Network users who are running PTOP programs will need to convert them to NetIPC/RPM programs before running them on an NS 3000/iX network. Refer to the NetIPC 3000/XL Programmer’s Reference Manual and the Using NS 3000/iX Network Services for more information.

•Nowait I/O RFA is not available with NS 3000/iX. Privileged mode programs that use nowait I/O Remote File Access over an NS 3000/V network will need to be modified before they can be run on an

NS 3000/iX network. Refer to Using NS 3000/iX Network Services for more information.

Obtaining Device Status Information

On MPE V systems, the SHOWCOM command returns status information about communication devices such as Local Area Network Interface Controllers (LANICs). On NS 3000/iX systems, this information is available with the LINKCONTROL...;STATUS command.

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.
