  4. Platform Overview • Most platforms plan a transition to 64 bit technology • R/3 on DIGITAL UNIX on 64 bit since 1992: • 64 bit Operating System • 64 bit Database • 64 bit R/3 Kernel and application server • R/3 on AS/400 on 64 bit since 1995: • DB2/400 full integrated in OS/400 • 64 bit Operating System and Database • 64 bit R/3 Kernel and application server

  5. Platform Overview • Most UNIX Platforms are on 64 bit technology today • Databases complete their 64 bit transition soon • R/3 is ready for the transition to 64 bit

  6. Memory Based Computing Platform Overview Technical Aspects New Technologies

  7. Technical Aspects • 64 bit Memory Management: • No more 4 GB address space limitations • 4 BILLION TIMES MORE ADDRESS SPACE ! • Applications can access terabytes of disk and memory • Higher profitability of memory resources • System management becomes easier • Bigger database tables and index data: • Less archiving • Less reorganization • Design simplification of large applications

  8. Technical Aspects • 64 bit Performance : • Faster low level operations • Faster memory mapped file access, caching and swapping • Faster analysis of bigger amounts of data

  9. Technical Aspects • Advantages for R/3 on 64 bit: • Unlimited R/3 user context • Unlimited addressing capabilities for R/3 memory objects • + 40 % overall performance win for R/3 • SAP is always ready for new technologies • SAP is flexible

  11. Usercontext Usercontext Usercontext Application data Application data Application data Shared database New Technologies • No memory based computing: • Typical C/S implementation • Extensive resource requirements

  12. Usercontext Usercontext Usercontext Buffered, sharedapplication data Shared database New Technologies • First step to memory based computing: • Buffering with R/3 2.0 to reduce disk I/O • First level memory based computing

  13. Usercontext Usercontext Buffered usercontext Buffered, sharedapplication data Shared database New Technologies • Second step to memory based computing: • Buffering with R/3 3.0 to reduce disk I/O • Faster user context switch • Advanced memory based computing

  14. Shared database New Technologies • The latest in Memory Based Computing: • Buffering with liveCache • Optimized and Synchronized data structures allow for a new type of business functionality Usercontext Usercontext Buffered usercontext Buffered,shared application- specific data Buffered, sharedapplication indep.data liveCache

  15. New Technologies • What is liveCache ? • A memory resident object management technology which allows new business processes through real time processing of vast amounts of data using very large memory and parallel processing • Application data in memory: • Optimized for use of large memory • Ready to exploit 64 bit computing ! • Enables business processes not possible before due to performance and memory limitations

  16. New Technologies • Example: • 80-95% of product planning run is database I/O • liveCache holds large amounts of data in main memory • Supply chain planning in minutes rather than hours ! • Lots of other possible 64 bit based new technologies
