SAP's BW is a data warehouse providing analytical tools against multi-dimensional business data. BWA is an optional in-memory accelerator for BW. Both BW and BWA can run on a certified subset of Dell's standard range of servers and storage. BWA holds the BW data in memory across a set of blade servers. Dell doesn't sell SAP's BWA software but the hardware along with system integrator's services on the installation. The blades used are PowerEdge M610 in a dedicated M1000e chassis. In order to get a qualified BWA configuration, please contact sap_sizing@dell.com
Having the data in memory greatly accelerates the queries run against it. It’s sized and licensed by the total amount of memory required. The user count of BWA is not a significant sizing factor. Determining the needed memory is a joint activity between the customer, SAP and Dell. Once determined, BWA is licensed for that amount of memory in 4GB increments. Licensing 4GB of physical RAM costs 12,500 USD, but there are limitations. Typical amounts are between 32GB and 256GB of RAM, though can be much higher. The BWA memory is distributed over a number of blades, each blade can have up to half of its physical memory assigned to BWA. In addition to these production blades there would typically be two cold spare blades and some test blades.
