Disk Cache Settings
For applications with high I/O demands, such as Primavera, it is recommended to choose writeback mode.
- none: This option bypasses the host cache to offer an ideal mix of native-level performance and data protection, making it the default for production environments and live migrations.
- writeback: This mode prioritizes performance by using the host's RAM as a buffer, but if the host fails before data is written to disk, significant data loss can occur.
- writethrough: To ensure the highest data integrity, each write is only confirmed once it has reached the physical storage; however, this results in very slow write speeds.
You must reboot the system after applying this cache setting change.
