The deal was announced on 30 October at this year's Linux World conference in Frankfurt, and makes SuSE the chief European distributor for IBM's DB2, Websphere, Lotus and Tivoli product lines.
IBM will "actively support" sales of SuSE's products, including SuSE Linux Groupware Server with Lotus Domino R5, SuSE Linux Database Server with IBM's DB2 Universal Database, and IBM's Websphere Commerce Suite 5.1 for Linux. IBM will also deliver related contracts through SuSE.
IBM is firmly committed to Linux, said Erich Clementi, the company's vice-president for system sales in Europe, the Middle East and Africa.
"We believe there is a new generation of e-business underway. We think the new generation will be built on open source," he told Linux World delegates.
Open standards, rather than company-owned proprietary standards, will be the industry standards of the future, Clementi said.
"We think the time of proprietary standards is over, and that's a remarkable statement coming from a company that probably invented proprietary standards some time ago," he added.
IBM has made no secret of its support for Linux. So far, the company has announced plans to invest some $1.3bn (£890m) in development and support for the open source operating system.
