HANA Data Tiering

Business Value

  • Greatly increase HANA data volume while significantly lowering TCO.
  • Allow customers to do things they never thought possible before.
  • Allow customers to EASILY use HANA advance
platform on SAP and non-SAP datasets in real-time.
  • Easily analyze many datasets and very huge datasets faster and easier and less expensively than anyone ever thought possible.
  • Significantly lower time to develop and deliver solutions (TTD) due to supporting simpler columnar data models leveraging horizontal and vertical partitioning across data tiers delivering a much lower TCO solution.
  • HANA Data Tiering Whiteboard

    HANA Data Tiers

    Default: Columnar in-memory storage

    • Incredibly fast and easy
    • Very low TTD supports simpler easier data models

    HANA on-disk: Columnar on-disk tightly coupled storage

    • Very very fast and easy
    • Slower than in-memory but 10s-100s times faster than traditional databases
    • Very low TTD supports simpler easier data models
    • 5x HANA total storage
    • Tightly coupled with in-memory storage supporting hot/warm horizontal and vertical partitioning
    • Lower cost
    • Single security and governance model

    HANA Relational Data Lake: Columnar on-disk loosely coupled storage

    • Very very fast and easy
    • Slower than in-memory but 10s-100s times faster than traditional databases
    • Very low TTD supports simpler easier data models
    • Designed for 10TBs to 10PBs data
    • Extremely low cost
    • Single security and governance model
