Validation Guide
We recommend running regular SAP HANA health checks to verify the performance of
the underlying storage environment. The following documents describe SAP HANA
configuration mini-checks:

SAP Note 1969700:

SAP Note 1999930:
Access to these documents requires an SAP username and password.
Every SAP HANA node requires storage devices and capacity for the following:

Operating system boot image

SAP HANA installation (/hana/shared)

SAP HANA persistence (data and log)

Backup
Note: The formulas for capacity sizing in
by SAP. Always check the latest version of the white paper for updates before you determine
capacity requirements.
Operating system boot image
The overall capacity calculation for the SAP HANA installation must include the required
capacity for the operating system when the SAP HANA nodes boot from a volume on an
SC Series model, that is, when they boot from the SAN.
Every SAP HANA node requires approximately 100 GB capacity for the operating system,
including space for the /usr/sap/ directory. When booting from a SAN, follow the best
practices in the Dell Compellent Storage Center and Boot from SAN with FCoE Best
Practices Guide.
SAP HANA installation (/hana/shared)
For installation of the SAP HANA binaries, as well as the configuration files, traces, and
logs, every SAP HANA node requires access to a file system that is mounted under the
local mount point, /hana/shared. An SAP HANA scale-out cluster requires a single
shared file system, which must be mounted on every node. Most SAP HANA installations
use an NFS file system for the single shared file system. The file system you choose
depends on your infrastructure and requirements. The options are:

NFS-server-based shared file system

NAS system, such as the Dell EMC Unity system, Dell EMC VMAX embedded
NAS (eNAS), or Dell EMC Isilon system, which can be used to provide an NFS
share for the SAP HANA shared file system
The SC Series array uses block storage, which can be used to create a shared file system
using a cluster file system such as General Parallel File System (GPFS) or Oracle Cluster
File System 2 (OCFS2) on top of the block LUNs. SUSE provides OCFS2 capabilities with
the HA package (a SUSE license is required). The HA package is also part of the SUSE
Linux Enterprise Server (SLES) for SAP applications distribution that is used by most of
the SAP HANA appliance vendors.
