In an SAP HANA scale-out implementation, install the SAP HANA database binary files under the /hana/shared mount point on a shared file system that is exposed to all hosts of a system. If a host must write a memory dump that can read up to 90 percent of the RAM size, the memory dump is stored in that file system. Based on your infrastructure and requirements, the following options are available:
NAS systems can provide an NFS share for the SAP HANA shared file system.
Block storage can create a shared file system using a cluster file system such as the General Parallel File System (GPFS) or the Oracle Cluster File System 2 (OCFS2) on top of the block LUNs. SUSE provides OCFS2 capabilities with the high availability (HA) package. The HA package is also part of the SUSE Linux Enterprise Server (SLES) for SAP applications distribution from SAP that most SAP HANA appliance vendors use.
Note: A SuSE license is required for HA.
