Disk Cache Configuration

For I/O-intensive applications such as Primavera, the writeback option is recommended.

• none: Delivers an optimal mix of native performance and data protection by sidestepping the host cache, establishing it as the default setting for production environments and live migration.
• writeback: Achieves peak performance by leveraging the host's RAM to buffer data, though it carries a substantial risk of data loss if the host fails before completing the sync to disk.
• writethrough: Guarantees the highest level of data integrity by ensuring each write is confirmed only after it reaches the physical storage, but this comes at the cost of considerably slower write operations.

A system reboot is necessary after modifying this setting.
