3.6.4 Enter Performance Settings for SAP HANA
The system tuning application saptune allows you to tune your system automatically and comprehensively as
recommended by SAP. The following SAP Note contains a detailed description: SAP Note 1275776 - Linux:
Preparing SLES for SAP environments .
# saptune solution apply HANA
For more information, see Tweak the Default System Settings for SAP HANA [page 45].
3.6.5 Updates and Patches
If you have not used the update option during the deployment or your system was registered later on, make
sure to get the newest updates in order to have the latest versions of the resource agents and other packages.
A prerequisite is a valid subscription for SAP Applications. There are multiple ways to get updates like SUSE
Manager, SMT / RMT or directly connected to SAP DB Control Center (SUSE Costumer Center).
Depending on your company or customer rules, use zypper update or zypper patch.
A manual software update must be triggered from each node.
zypper patch installs all available needed patches.
# zypper patch
zypper update updates all or specified installed packages with newer versions, if possible.
# zypper update
3.7 Create the Partitions for SAP HANA
Look at the disks and partitions of SAP HANA itself. Where the size of the partitions depends on the amount of
main memory (SAP Sizing), the size can vary based on backup/snapshot configuration, and the desired SLAs.
In the SAP HANA TDI – Storage Requirements Guide
, you find the following statements:

The I/O performance requirements that have to be fulfilled by the storage subsystem mainly rely on the
scenario or the SAP HANA database.
The filesystem must be compliant with the SAP documentation (dominant are XFS, NFS4 and Spectrum
Scale/GPFS).
Storage systems used for SAP HANA must fulfill a certain set of KPIs for minimum data throughput and
maximum latency time. In the course of both the SAP HANA appliance and the SAP HANA Enterprise
Storage certification the fulfillment of those KPIs is checked using the SAP HANA Hardware Configuration
Check Tool (HWCCT). All KPIs must be met for each SAP HANA compute node connected to a given
storage system. Each individual deployment must be revalidated.
