Why is SAP NetWeaver BI Accelerator appliance only shipped on Linux?
The BI Accelerator runs under 64-bit SUSE Linux (SLES). 64-bit is necessary to use the bigger address space for large data volumes. SAP has chosen Linux because this is a vendor-independent operating system. There are no plans to port this solution on other operating systems because the reduced available combinations of hardware and software components allow for a much robuster environment by encouraging a specific, pre-defined setup. SAP and its partners can make sure that hardware components are appropriately configured to support the underlying software architecture. This translates into lower TCO and better performance.
