SAP HANA installations on VMware vSphere require the following storage devices:
The disk is created when the virtual machine is deployed. The virtual disk file (VMDK) can reside on any datastore that meets the installation requirements, that is, has vMotion support.
The /usr/sap directory can be a mount point under the OS root directory. Adjust the size of the root device correspondingly. Alternatively, you can use and mount a separate virtual disk under /usr/sap/<SID>. Dell EMC recommends this method for storage-based cloning and when using SAP instance cloning tools such as SAP Landscape Management (LaMa).
The /hana/shared file system stores the SAP HANA installation binary files, configuration files, and trace files. The size of the file system depends on the size of the SAP HANA installation (database size and number of nodes). For capacity sizing guidelines, see the SAP HANA Storage Requirements white paper. The white paper is provided as an attachment to SAP note 1900823: SAP HANA Storage Connector API. For configuration details, see SAP HANA shared file system in this guide.
Each active SAP HANA node (scale-up node or worker node in scale-out deployments) requires two devices to persist the in-memory database to disk and to write the transaction log. Because the SAP performance requirements for the storage devices apply only to these two file systems, it is important to consider storage-configuration best practices when you set up an SAP HANA production environment. The size of the data and log devices depends on the actual database size. For more information, see the SAP HANA Storage Requirements white paper in SAP note 1900823: SAP HANA Storage Connector API.
