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.
SAP HANA scale-out deployments require a shared file system that is mounted on every SAP HANA node in the cluster.
In physical environments, this file system is provided as a network file system (NFS) that is shared by storage systems with network-attached storage (NAS) capabilities. Examples include Dell Unity XT, PowerStore, and PowerScale systems. If a NAS array is not available, vSphere with native Linux functionality offers an alternative. A Linux VM (non-SAP HANA node) running an NFS server process provides the NFS share. The NFS server process exports a file system that is mounted on all the SAP HANA cluster nodes, and vSphere Fault Tolerance provides reliability.
For information about setting up an NFS server on a Linux VM, see the VMware Virtualized SAP HANA with Dell EMC Storage Deployment Guide.
