There is a proven way to avoid both cost and complexity….
For very large, highly volatile data sets being processed in real time, there are much more cost effective Flash optimized, ACID compliant solutions out there (for example Helium from Levyx using off the shelf SSD and multi-core processor based servers) that are definitely worth exploring and integrating for SAP and other real time applications. They deliver in-memory like performance via a simpler and denser (scaled-in) infrastructure, and are 5 to 10x more affordable to implement delivering both data persistency and 100’s of millions of transactions per second. Not sure why one would want to use either expensive system memory (in-memory) spread across 10s and 100s of servers or high end enterprise flash based storage systems for that when a simpler and much more cost effective approach exists - why go complicated-expensive when you can go simple-smart?
