Which file systems are supported for the data and log volumes of the SAP HANA...

In the SAP HANA 2.0 database system, the supported file systems for data and log volumes are crucial for ensuring optimal performance and reliability. The correct answers are:

XFS (A): XFS is widely recommended for use with SAP HANA due to its high performance, scalability, and reliability with large data volumes, which are typical in an in-memory database such as SAP HANA.

GPFS (C): Also known as IBM Spectrum Scale, GPFS is a high-performance shared-disk file system that can be used with SAP HANA for scenarios requiring distributed file systems with high availability and large-scale data capacity. EXT4 (D) and Btrfs (B) are not recommended or supported for SAP HANA installations, especially for production environments, due to their limitations in handling large files and high I/O operations effectively, which are critical for the performance demands of SAP HANA.
