Networking Concepts

Network Design Questions

To connect two networks that run on different protocol stacks, a gateway is needed. A gateway does conversion between the two protocols at every layer until the application layer.

6.Is the set of nodes you wish to connect composed of some nodes that are in close proximity to one another (for example, in the same building) and other nodes that are geographically distanced (for example, in different buildings or different cities)?

If so, you may wish to use ThinLAN 3000/iX, Token Ring 3000/iX, FDDI, 100VG-AnyLAN, or 100Base-T networks for nodes that are located near one another and Point-to-Point or X.25 links for nodes in different buildings or cities.

7.Will HP 9000s or other minicomputers need to be part of the network?

If so, consider ThinLAN 3000/iX (or its ThickLAN option), Token Ring 3000/iX, FDDI/iX, 100VG-AnyLAN, 100Base-T, or X.25/iX System Access.

8.Do you need access to nodes on public or private X.25 networks? If so, consider using DTC/X.25 iX Network Links.

9.Is a subset of nodes either geographically or organizationally distanced from another subset of nodes?

If so, you may wish to establish a network boundary between them in order to make them two separate networks joined by a full gateway or router. Alternatively, you may want to use subnets to divide one network into two or more physically distinct subnetworks.

10.If you must use a gateway half, is the partner-gateway half in the same building or further away?

If the two gateway halves are in the same building, you can use a direct connect link between them. If the two gateway halves are further away, you will need to use a dial link.

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.
