Armonk, New York-based IBM claims to have over 4,600 customers using Linux on its various hardware platforms, including the 10 new customers announced on Thursday. They include Air New Zealand, which has signed a strategic outsourcing agreement with IBM Global Services to replace 150 Compaq servers with a single IBM eServer zSeries mainframe running Linux, as well as IBM’s WebSphere, DB2 database and Tivoli systems management software. The Linux-based mainframe will replace 4,000 Microsoft Corp Exchange email and file and print clients with the Bynari open source email application.
