What is iSeries?
iSeries, formerly known as AS/400, is IBM’s midrange server platform designed for small to medium-sized enterprises that require robust performance, reliability, and scalability. Officially rebranded as IBM eServer iSeries in 2000, it combines hardware, operating system (OS/400), and database management into an integrated system. The iSeries is widely used for enterprise resource planning (ERP), customer relationship management (CRM), and other business-critical applications. Its strong backward compatibility allows organizations to run both legacy and modern applications, making it a cost-effective solution for businesses looking to modernize their IT infrastructure without sacrificing existing investments.
