Recommendations for physical and logical storage for /hana/log/ (e.g., SSD/NVMe).

The `/hana/log/` file system stands as the bedrock of transactional durability and recovery within any SAP HANA landscape. Its integrity directly impacts system uptime and data consistency. Consequently, the underlying physical and logical storage infrastructure for this critical component demands meticulous design and implementation, far beyond standard enterprise storage considerations.

A fundamental principle for `/hana/log/` is strict separation from other volumes, particularly data volumes. Co-locating the log with other high-I/O or general-purpose storage introduces contention and unpredictable performance, severely hindering the self-healing system's ability to react swiftly to log-related issues. Dedicated resources ensure consistent, low-latency write operations essential for transaction commits.
