Out of Band Sanitize Disk Erase Support
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
With Gen10 HPE Proliant servers and later the ``ilo5`` hardware type supports
firmware based sanitize disk erase as a clean step. This feature requires the
node to be configured to ``ilo5`` hardware type and its management interface
to be ``ilo5``.
The possible erase pattern its supports are:
* For HDD - 'overwrite', 'zero', 'crypto'
* For SSD - 'block', 'zero', 'crypto'
The default erase pattern are, for HDD, 'overwrite' and for SSD, 'block'.
.. note::
In average 300GB HDD with default pattern "overwrite" would take approx.
9 hours and 300GB SSD with default pattern "block" would take approx. 30
seconds to complete the erase.
