SAP Hana in memory strategy
SUSE Linux Server hosts a number of SAP HANA processes. The memory reservation for each process is managed by the SUSE Linux server.
The Linux operating system reserves memory for programme code, programme stack, and static data when SAP HANA starts. At the request of the SAP HANA server, additional data RAM can be dynamically reserved by the operating system.
To monitor and measure memory consumption, SAP HANA establishes a memory pool.

All memory data and system tables, threads, staging calculations, and all other data structures required to manage the database are stored in the memory pool.
SAP HANA memory acquires more memory from the pool when it’s needed for board growth or temporary computations.
