4.9. File systems and storage
Support for Data Integrity Field/Data Integrity Extension (DIF/DIX)
DIF/DIX is supported on configurations where the hardware vendor has qualified it and provides full support for the particular host bus adapter (HBA) and storage array configuration on RHEL.
DIF/DIX is not supported on the following configurations:
- It is not supported for use on the boot device.
- It is not supported on virtualized guests.
- Red Hat does not support using the Automatic Storage Management library (ASMLib) when DIF/DIX is enabled.
DIF/DIX is enabled or disabled at the storage device, which involves various layers up to (and including) the application. The method for activating the DIF on storage devices is device-dependent.
