【Mitsubishi Electric】Entrance Series

Mitsubishi Electric announced the new Entrance series of servers in September 2000. These server models gave seamless coverage of e-business and mission-critical applications in one unit.

The Entrance Series implemented an application integration hub (AIH), which connected mission-critical applications, e-business applications, and data-warehouse applications by means of an XML-based request broker, known as an Internet integration broker (IIB). Making use of AIH, Entrance models offered a rich repertoire of solutions, which utilized open database systems such as Oracle 8i and SQL Server, from Web front-end systems to back-end data warehouses, such as Internet information delivery systems, Internet order-taking systems, and Web application development and execution environments.

Entrance servers achieved a dramatic increase in performance by running e-business and mission-critical applications on four function-specific processors, as follows:

  • Integrated Windows processor (IP): An Intel processor for high-speed execution of mission-critical and information-retrieval/analysis applications in Windows NT
  • Extended Windows processor (XP): An Intel processor that runs Internet applications; for security reasons, this processor is separate from the processor running mission-critical applications
  • DP-XP processor (DP): A processor running the DP-UX core business operating system Mitsubishi Electric had developed for office computers
  • Relational database processor GREO: A Mitsubishi Electric-developed relational database processor for sorting, generating index keys, and running database searches; can improve sorting speeds by 100 to 1,000 times compared to a system without GREO

The Entrance series consisted of the model 700, which boasted the top performance, reliability, and scalability of the series, the model 500, a compact model that rivaled the model 700 in performance, the model 300, which delivered excellent cost effectiveness, and the model200, a model that prioritized affordability.
