Study Notes
Linux Operating System Requirements for SAP HANA
- SAP HANA runs on SUSE Linux and Red Hat Linux, depending on the CPU architecture.
- Before installing SAP HANA, ensure you follow recommendations in the relevant SUSE (SLES) and Red Hat (RHEL) SAP Notes.
- The operating system must fulfill all SAP HANA requirements to allow installation and operation.
- The correct operating system settings are critical to optimize performance.
Supported Operating Systems
- SAP provides specific SAP Notes with recommended OS settings for SUSE Linux Enterprise Server (SLES) and Red Hat Enterprise Linux (RHEL) versions.
- Recommended OS settings are available for different versions of SUSE and Red Hat Linux, including SLES 15/SLES for SAP Applications 15, SLES 12/SLES for SAP Applications 12, RHEL 9, RHEL 8, and RHEL 7.
- Specific SAP Notes address HANA on IBM Power systems with varying hardware configurations (including LPARs).
Supported File Systems
- SAP HANA supports various file systems, but only tested ones are guaranteed.
- Specific SAP Notes (e.g., SAP Note 2622671) list supported file systems.
- The recommended file systems are for the database data volume, log volume, and backup volume.
- Using suitable file systems is critical for performance stability and preventing issues.
File System Layouts
- Single-host: A unified shared storage holds data, log, and installation paths.
- Multi-host: Multiple hosts connect to shared storage containing installation, data, and log folder paths on separate partitions. This accommodates high availability, where a standby host can take over the failing host's partitions.
- A separate SAP Note (2622671) details SAP HANA Certified and Supported Hardware's supported file systems.
Disk Space Requirements
- Recommendations for disk space vary, depending on the specific SAP HANA configuration.
- SAP recommends keeping the data and log volumes on different disks.
- Installation paths and system instances require at least a minimum allocated space.
SAP Notes
- SAP Notes provide critical information regarding recommended OS settings, supported file systems, and installation guidelines.
- Consult relevant SAP Notes for specific versions and configurations for accurate, updated details.
