Why does SAP de-support 32-bit server operating systems for new releases from 2007 onwards?
SAP software can easily serve several hundred users on a single SAP application server. SAP software also handles jobs working on huge data sets (easily several GB). SAP introduced 64-bit capabilities into its architecture as early as 1998 in order to be able to serve both needs with optimal performance and greatest ease of use. Experiences gained in development and service and support clearly prove the benefits of 64-bit environments for SAP software. On 64-capable Unix and OS/400 platforms , de-support for 32-bit already happened with SAP release 6.20 and was very well received by our customers.
