SAP HANA has completely transformed the database industry by combining database, data processing, and application platform capabilities in a single in-memory platform. The platform also provides libraries for predictive, planning, text processing, spatial, and business analytics -- all on the same architecture.
However, despite all these wonderful attributes, there is still the small detail of TCO. HANA appliance costs are coming down, but it is still expensive, yet still there is the ideology that you simply take all data on your migration journey, why not, HANA can handle it? Yes, it can, easily, and yes there is compression to consider, however, why would you take data that is of no benefit to your business onto such advanced technology? Moving business complete and obsolete data onto lower tier storage will significantly reduce your HANA Migration TCO.
A RightSizing SAP for HANA strategy, will keep a migration project under control, and reduce costs, simply by managing data prior to migration and ongoing throughout the systems lifecycle, reducing TCO & HANA appliance size, controlling data growth so appliance refresh time is extended, along with all the usual attributes data management brings to an SAP landscape
