Lenovo and IBM have reached a US$2.3 billion deal in which Lenovo will acquire IBM's x86 server business, including IBM’s System x, iDataPlex servers, and other server maintenance operations, according to Lenovo's press release on January 23. IBM will retain the System z mainframes, Power-based Flex servers, and storage systems while continuing to develop its Windows and Linux software for the x86 platform. And as part of the agreement, Lenovo will become a reseller of IBM storage systems and software. In the interim, IBM will continue to provide maintenance and customer support on behalf of Lenovo. The transaction is still subjected to the approval of regulatory authorities. IBM sold its ThinkPad line of PCs to Lenovo in 2005.
