Which Linux file system does SAP recommend for HANA data and log volumes on AWS?
Show answer and explanation
Answer: D
SAP supports XFS for HANA data and log volumes on Linux. XFS handles large files and parallel I/O well, scales to the volume sizes used for HANA, and is the default in the major SAP-certified Linux distributions. ext3 is an older file system with weaker scalability, NTFS is a Windows file system, and FAT32 has file size and robustness limits that make it unsuitable for a database.
Why the other options are wrong
- A. ext3 is an older ext file system with limited scalability and is not the SAP-recommended choice for HANA.
- B. NTFS is used by Windows and is not the file system for Linux-based HANA.
- C. FAT32 has a 4 GB file size limit and lacks the journaling and performance characteristics needed for HANA.
Exam tip. SAP HANA on Linux uses XFS for data and log volumes.
