n is 0 through 20.
The data structure contains the descriptor of the Self-test that the device has performed.
Each descriptor is 24 bytes long and the self-test data structure is capable to contain up to
21 descriptors. After 21 descriptors has been recorded, the oldest descriptor will be
overwritten with the new descriptor. The self-test log pointer points to the most recent
descriptor. When there is no descriptor, the value is 0. When there are descriptor(s), the
value is 1 through 21.

Cactus Technologies
®
-910S-P1 series SSDs support the following additional features:
•
jumper triggered full disk erase
•
AES256 hardware encryption
7.1. Jumper Triggered Full Disk Erase
A hardware jumper is located at the back of the drive chassis. When the two pins are
shorted together for a duration of 60ms or more, it will trigger an internal full disk erase
operation. This erase operation will erase all user accessible blocks and any re-
assigned/spare blocks that may have contained user data. The drive's firmware is not
erased and the drive will remain usable after the erase operation.
