Before you install the SAP HANA binary, configuration, trace, and log files, ensure that every SAP HANA node has access to a file system that is mounted under the local /hana/shared/ mount point. In an SAP HANA scale-out cluster, a single shared file system is required and must be mounted on every node. Most SAP HANA installations use a Network File System (NFS) for this purpose. PowerStore unified storage systems can provide this file system with the NAS option. If a NAS or NFS option is available to provide the /hana/shared mount point, you can configure PowerStore as block-only.
Calculate the size of the /hana/shared/ file system by using the formula in the SAP HANA Storage Requirements white paper. This paper is included as an attachment in SAP Note 1900823: SAP HANA Storage Connector API (access to the note requires SAP login credentials). Version 2.10 of the white paper provides the following formulas.
Sizeinstallation(single-node) = 1 x RAM but max 1 TB
Sizeinstallation(scale-out) = 1 x RAM_of_worker per four worker nodes
