1. Purpose
The contents of this document describe the initial physical configuration required to support WELLCO ERP suite for development, test, and production.
 
2. Scope
This configuration will support the WELLCO ERP suite system requirements.
 
3. Technical Description of the Technological Infrastructure

This configuration needs to support the WELLCO ERP suite system requirements for all environments, development through production. The following environments will need to be supported for the WELLCO ERP suite development and implementation:

  • Design Systems

  • Test Systems

  • Product Data Management

  • Quality Systems

The application components to be supported for the delivery systems are as follows:

  • Oracle Database Instances to support above environments.

  • Tuxedo Application Server Domains for specific Environment.

  • UNIX and NT Process Schedulers for specific environment

  • Web Server(s) for specific environment.

  • Vista Plus for specific environments.
4. Data and Processes to be Distributed
For WELLCO ERP the expected number of concurrent users is around 400-500. The transaction volumes in the development and test regions will be considerably less and based upon the size of the development and testing teams.
 
5. Description of the System Physical Configurations
5.1 Physical Server Requirements

The following describes the number and types of servers required:

 

UNIX Servers:  (Database Servers, Application Servers, Web Servers, and Process Scheduler

  • 4 Development/Test Servers

  • 3 Production Servers (Service Guarded)

Windows 2000/NT Servers:

  • 1 Development/Test Server (Partitioned into multiple virtual machines)

  • 4 Production Servers

5.2 Physical Server Diagram

5.3 Availability Requirements Implementation

The production web, application and database server environment should be configured as part of a high availability cluster but would not be failed over to the production HRMS server except for testing.

 

The W2K NT Availability configuration will be represented in the section 5.5 NT Process Scheduler Processing/ Memory Requirements diagram..
