What is difference between HANA appliance and TDI?
TDI differs from the initial appliance delivery model, a pre-configured hardware setup with pre-installed software packages implemented by a SAP HANA hardware partner. Instead of an appliance, TDI provides several options for the hardware components required to run a SAP HANA environment.
How is SAP HANA different from other databases?
Unlike any other databases which use to store data on the hard drive, SAP HANA stores it in-memory. That means when you need the data; the system can access it directly from the in-memory storage rather than calling it up from the hard drive.
