About AS400IBMSystems.com
Why this site exists, how it fits the wider IBM Power ecosystem, and what you will find here.
The IBM i and AS400 Knowledge Base for the IBM Power Era
AS400IBMSystems.com exists to give IT professionals, executives, and anyone researching legacy IBM midrange systems clear, independent answers ... from basic AS400 terminology to current Power11 upgrade planning.
Many organizations still describe their environment as AS400 even when it has been running IBM i on modern Power hardware for years. This site preserves that terminology deliberately, because that is how people actually search and talk about these systems, while connecting it to current IBM i and IBM Power concepts.
Education First, Sales Second
This site is built as a knowledge base, not a sales page. Definitions, history, and foundational concepts come first. When a topic naturally leads toward an upgrade or modernization decision, we point toward more specific resources rather than trying to sell anything directly here.
- AS400IBMSystems.com answers what a term or concept means and how it fits the wider IBM Power picture
- AS400IBMSystem.com (singular) covers upgrade guides, pricing, and migration planning
- BigTech Reseller connects buyers to IBM Business Partners and reseller discovery once a direction is clear
