File Systems

This section describes the file system planning of the SAP ASE database. For details, see Table 1. For SAP applications powered on the ASE database, the file system planning is the same as that of the applications using the HANA database. For details about the file system planning for SAP applications, see the SAP NetWeaver User Guide.

For the single-node ASE system, each file system needs an EVS disk.
