SAP HANA installations require a file system to store the SAP HANA binary, trace, and configuration files. This file system is mounted under the /hana/shared mount point.
In SAP HANA scale-up (single-node) deployments, this mount point can reside on the local system device. SAP HANA requires approximately 1 x the RAM memory capacity for the /hana/shared file system.
Note: SAP HANA scale-out deployments are currently not supported on HCI using vSAN storage.
